TinyChats Privacy Policies and IP Exposure

TinyChat is a service that provides users with a web based chat room and the ability to stream multiple live webcams in their rooms.  Their service is very simplistic and uses an IRC like interface, similar to, which the exception of the ability to have more than one cam streams going at a single time.  Like most cam sites, they have terms of services and privacy policies that disallow certain behaviors, such as vulgarity or nudity on cam.  But, TinyChat goes a step further with their polices when they feel that users have misbehaved and punishes them by not only closing the room, but publishing a list of all the users who were present when the room was running along with their full IP addresses.

Tinychat may terminate any user's access to the network, Web site and service and remove any content posted, for any reason. Tinychat reserves the right to modify or discontinue and portion or component of the service at any time and with or without notice. Tinychat shall not be liable to any user or any third-party for any termination or modification of service. By using the tinychat service you agree, that should any room be closed for any reason that all users data who may be in the room may be disclosed publicly.
 TinyChat Privacy Policy and Terms of Service

This is an abhorrent practice on TinyChat's part to expose any members IP address publicly without any way for the user to request it be removed.  This information can give away a users location and allow individuals with malicious intent to potentially attack the IP address using denial of service attacks or port scans to look for vulnerabilities or holes in the users system.

The Misc Incident

Last night on's Misc section a user started a thread that linked to a Tinychat room with him and a female companion.  According to the user, franchise16, no nudity was recorded on cam during the chat session, but in the end, the Tinychat staff felt it necessary to close down the room and then proceeded to display the IP addresses of all the users who were currently in that room at the time.

As of the time of this posting, Tinychat still has left this information up.  As a further example of the abuse potential this opens up, a number of users took the entire list of IP addresses and claimed to post them on 4chan, to allow the members their to potentially exploit the list for nefarious purposes.  I cannot verify this claim however.

I spoke to the user who started the Tinychat room, franchise16, and asked him for an overview of the events. Here is a summary of what he said happened:

Made thread bout POF [Plenty of Fish] girl comin over
[She] Came over, had webcam open and screen off on macbook, told them mac was for music
Carried it around with me
Brought on to porch where we fooled around, was too dark to see
Had about 500 users viewing it in the room
Brought it inside and into the room
We made out for a big on bed
Took titties out, no nudity was recorded I dont believe
[The feed] Was cut about 2 min after mac was brought into room
Rest happened off cam
All IPs were posted in tinychat room but for some reason not me or any other canadian brahs
I asked him if there was any nudity shown on cam and he responded that there was not.  He also confirmed that the girl was of legal age (18) and was therefore not any sort of situation of child pornography.  franchise16 said that no Tinychat staff warned him in advance that he was violating in terms of that he should stop the cam feed before the room was closed and all the users IPs were posted.  Regardless if there even was nudity displayed on cam in the Tinychat room, Tinychat should not endanger it's users security by publicly "outting" them by posting their IP addresses when a room is terminated.

Because of this incident, I would recommend that no one use Tinychat.  The risk of having your IP posted without any warning or notification is not one that you should be willing to risk.  When using IRC servers that do not obfuscate IP addresses, users are aware that their IPs are being displayed publicly, but Tinychat doesn't do this openly or have any sort of whois command so that users IPs can be displayed to other users, outside of Tinychat staff.

I will contact Tinychat's support and report back with their response.

UPDATE: Tinychat has responded to my inquiry.  See the post TinyChat Responds to Inquiry Regarding Public IP Disclosure  for the follow up.

Homemade NO2 Preworkout Stack

NO2 blend products like SuperPump and NO-Xplode are all the rage nowadays.  These type of pre/during/post workout supplements don't fit into a particular category, but are generally meant to be used to give you a boost of strength, energy and a massive muscular pump during your workout that can be very motivating to help you out in the gym.  But, they sort of take a "kitchen sink" approach when it comes to what's in them.  Generally, they have a variety of different amino acids, including creatine and arginine especially.  They also have a blend of some type of carbohydrates and a delivery system to try and get them into your bloodstream as fast as possible. Some have BCAAs and others don't.  They often times use a lot of fancy proprietary ingredients and you can never tell how much exactly of anything you're getting.  And, a lot of times, they have different stimulants, such as caffeine and exotic herbal blends to give you an extra boost to lift harder and heavier.

Although these products provide a lot of good motivation from the extra energy and the visual pump you get during and after the workout the real question is whether they actually increase strength and body composition beyond that of the supplements that we know do, like creatine and whey protein.  Originally, an NO2 product was just made up of the amino acid arginine or an a derivative of it, such as arginine bound to malic acid or ketoglutarate (AAKG) in a certain delivery system like a powder or pill.  The intended purpose was to increase levels of nitric oxide in the blood and the theory was that this would increase blood flow to the muscles, delivering all the rich nutrients from food/vitamins and amino acids to help build muscle, but there is no scientific data that shows this to be true.  Mostly what supplementing with arginine did was just give users a very noticeable pump in their muscles, but not much else. This is probably due to the cellular volumizing effects of just allowing more water and glycol into the muscle during the workout.  Some studies done with arginine showed no benefit on body composition, strength, 1 rep max (1RM) or any other positive factors. But, arginine has always been one of those bastardized amino acids.  It always looks good on paper, but no one can really say it has positive effects for body composition or strength. [4] Some studies show it increases growth hormone levels when taken at certain times in certain dosages, and others show nothing. [5,6] But one thing the supplement companies have learned is that arginine absolutely provides a visual effect in the form of what bodybuilders and weight lifters refer to as the "pump".  This is when you are lifting and the muscle becomes fuller and harder and this effect typically lasts several hours after the workout, but it is only temporary.

A more recent trend, NO2 supplements can be placed in just about any category of ergogenic (muscle building) and contain any range of ingredients.  The trouble is that a lot of these products are very expensive for the amount of servings they provide.  In this article I'll go over some ways you can make your own NO2/preworkout supplement yourself with bulk powder ingredients blended together in portions that work.  You can add in other ingredients based on your budget and your goals.  Then, you can simply flavor the formula yourself with whatever you like and drink it before and/or during your workout to get that same effect of cellular volumization, strength, energy and hopefully even some real body composition and ergogenic benefits too!


We'll start with creatine since we know that creatine has real life muscle building and strength effects. [1]  There are a lot of fancy creatines out there, such as creatine ethyl ester (CEE), Kre-Alkalyn, di-creatine malate, and so forth.  But, the only creatine that has been conclusively shown in studies to be effective is good ole' plain jane creatine monohydrate. [2]  That's not to say that the other creatines don't work -- they might even be better.  But no one has ever tested them side by side to determine that.  There was only one study comparing creatine monohydrate to CEE side by side and creatine monohydrate was shown to be superior in every way. [3] So, I'll show you a few examples of what creatine powder you might want to choose for your own blend and get that one based on your budget or if you're just feeling experimental and want to try one of the other more exotic creatines out there.  Ideally you want to be getting at least 5g of creatine per serving or per day, but you can go up to 10g if you wish.  Some creatines like CEE only require a dosage of 3g per serving however.
I recommend the Higher Power brand creatine monohydrate for our NO2 mix.  It is the same price per gram as the Cheap Supplements brand, but it is also micronized for superior digestibility and absorption.


Just like creatine, there are a lot of different forms of arginine you can pick from based on your budget and what you want to go with.  I wasn't able to find arginine ethyl ester in pure powder form though, so we'll just be looking at plain free form arginine, di-arginine-malate, and arginine-alpha-ketoglutarate (AAKG).  Any one of them would be fine, but I would probably pick AAKG, although regular arginine would be just fine.  As a commenter below pointed out, plain arginine has an unpleasant taste, giving AAKG a leg up over its amino acid cousin.  One study using AAKG showed an increase in 1RM, but no effects on body composition or overall strength.  [6] However, arginine does also have other positive effects such as vasodilation and the potential to increase growth hormone (GH) and insulin like growth factor (IGF) levels. [4,6] But, the main reason we add it is to get that great pump effect we desire from our NO2 mix.  The problem with high dosing arginine is that it can cause upset stomach and so we want to keep it within the low range, giving us the benefits, without the negative side effects, so we will try and keep it within the 5-10g range.
I recommend the Higher Power AAKG arginine powder.  AAKG is what was used in one of the main studies looking at arginine for strength and body composition, but either of the two options would be also good.  The Higher Power brand is cheaper per gram than NOW.


I picked dextrose as the main carbohydrate for the NO2 mix for a couple reasons.  Firstly, it's dirt cheap.  Dextrose is the same thing as glucose, which is sugar in its simplest form. Ideally, you want a fast absorbing carbohydrate around the workout window (before/during/after) to replenish the ones that are being used during the exercise routine. Dextrose goes right into the blood stream to give you the insulin spike you want, and doesn't have any fructose in it to go through conversion in the liver. [7]  Sports drinks like Gatorade are good, but the fact that they have high fructose corn syrup is what takes away their advantage. [9] Other products have maltodextrin in them which is also not ideally suited for our purposes.  Dextrose is going to give you quick energy and get the ingredients in the blood stream faster.  As we know, creatine works best with a high GI (glycemic index) carb as it's delivery system, and so it's perfect for this.  Fructose is an extremely poor choice for this purpose and so I had to discount any product that had it or maltodextrin in it as I looked for suitable products for our blend.  Fructose is processed by the liver before it is released into the blood stream creating insulin resistance.  It also starts to create triglycerides from fat after consumption, leading to the potential to increase adipose (fat) tissue from repeated usage.  So, it's best to just stick with the basics and use dextrose. [8]  There are many special carbohydrate mixtures out there that have timed released formulas and other things like added amino acids and vitamins, but you shouldn't need those provided you already take a multivitamin daily and get plenty of protein from whole foods and/or protein supplements (like whey).

But, for low GI purists out there, you could also substitute dextrose for ground oatmeal powder, which is available premade by Protein Factory or you can blend it yourself.  In the past, I've found trying to blend oats into a powder to be a real chore, so I would just opt to buy the powder.  It should work just as well as dextrose, although possibly not quite as quickly and not as dramatic of an insulin spike will happen when you use it.  This is essentially a toss up between people who may be trying to follow a ketogenic diet routine (who would be going for the oats) or anyone else (who would choose dextrose).
I would recommend the NOW Dextrose powder.

Beta Alanine

Beta Alanine increases skeletal muscle concentrations of an amino acid dipeptide, carnosine.  Carnosine acts as a pH buffer in the muscle, helping to reduce lactic acid build up.  Lactic acid causes the fatigue and the burning in the muscle after long periods of high intensity training, so supplementing with beta alanine can help reduce this.  It also appears to increase strength in some, making it a great combination to take with creatine.  There are speculations that anabolic steroid usage leads to increases in skeletal muscle carnosine levels, similar to how they also increase creatine production (another reason why steroids are so effective at muscle building).  The dosing for beta alanine can be in the range of 4-6g daily, but it should be consumed throughout the day as taking one large dose causes an unpleasant tingling and stinging sensation in the skin, possibly caused by histamine release. [12,13]  The recipe I have at the bottom of the page lists 1g of beta alanine for our blend, but you will need to consume around 6g daily from other sources outside our blend.  Because users cannot tolerate more than 1g of beta alanine per dosage, it must be spread out.  This can be a bit tedious, but there are products, like Molecular Nutrition's PeakBeta, which comes as a time released beta alanine capsule that can be swallowed and delivered into the body throughout the day.  Although its more expensive than the powder, it is more convenient to use, so it's a trade off that will have to be made if you decide to use beta alanine.  You may consume teaspoons of beta alanine powder at multiple intervals during the day, or use a time released capsule product.  You should base this decision on both convenience and your supplement budget.

Carnosine’s role as an intracellular buffer is undisputed given its location within the skeletal muscle of humans and its chemical structure (Harris et al. 1990). Consequently, there is potential for supplementation with b-alanine to result in improved exercise performance, especially during high-intensity exercise. [13]
The NOW Beta Alanine appears to be the better deal at 5¢ per gram, so I would recommend that.  Alternately, you can use a time released beta alanine product.


Citrulline and citrulline malate (citrulline bound to malic acid) is a non essential amino acid that makes the conversion to arginine and arginine derivatives via enzyme pathways.  It was originally touted as being beneficial for aerobic exercise, but recent studies have shown that it has positive effects during anaerobic exercise.  For one, citrulline itself, when ingested, creates and causes the body to make and utilize some amino acids more efficiently. [10]

Citrulline-malate ingestion significantly increased the plasma concentration of citrulline, arginine, ornithine, urea, creatinine and nitrite (p < 0.05) and significantly decreased the isoleucine concentration from basal measures to after exercise (p < 0.05). Insulin levels significantly increased after exercise in both groups (p < 0.05) returning to basal values at recovery. [11]
Citrulline malate has also been shown to reduce post workout muscle soreness, also known as DOMS (delayed onset muscle soreness).  Although you can opt for the more expensive citrulline malate formula, l-citrulline alone would probably work just as well for your NO2 mix. I could not find it sold in bulk powder, only prepacked in capsules.  The dose for citrulline should be in the 1-5g per serving range.

Taurine is another amino acid that plays a key role in many exercise mediated actions.  It can increase endurance, strength and energy, as well as cause a great deal of cellular volumization and hydration to the muscles.  It's one of the main ingredients in Red Bull (along with sugar and caffeine) to give its users a positive feeling of well being and alertness.  It's also one of the cheapest ingredients here on our list, so that is another plus in adding it to our cocktail.  The dosage range can be anywhere from 1-6g per serving. [14]

The Nimbus Nutrition brand appears to be the cheapest at 2¢ per gram.

Caffeine (Optional)

Since many NO2 products use a variety of different stimulants I thought I would include the option of adding caffeine in here.  Obviously we don't want to use caffeine in powder form since it would be hard to measure out and scoop, so the best idea is to buy it in tablet form and split it.  A 200mg caffeine pill split into 4ths would give you 50mg of caffeine, which should be sufficient for a good amount of energy.  If you feel like you need more, you could always take half the pill.  Pills can be split using a cheap pill splitter found at a pharmacy or just using a butter knife (press into the tablet, don't saw at it) and obviously scored tablets are best for this, but normally more expensive.  The other issue with adding too much caffeine is that it acts as a vasoconstrictor (restricting blood flow) while the other ingredients, arginine especially, are trying to act as vasodialators (expanding blood flow).  So you don't want too much caffeine with your NO2 blend or it will negate the effects.


You can flavor your blend in whatever way you choose.  I would recommend buying unsweetened Koolaid packets and then adding the sweetener of your choice, such as Splenda (sucralose) which can be bought in large bags and is now sold as a generic product at most grocery stores or you could use Stevia powder.  Aspartame, saccharine, or sugar alcohols such as maltitol or xylitol would also be suitable alternatives, but obviously it is a personal choice.  You could use some table sugar (sucrose), but you wouldn't want to use much since you already have a high GI carb source from the dextrose, so an artificial sweetener would be preferred here.  Mix the Koolaid flavor of your choice and then sweeten to desired results per serving.  If you are blending it up all at once for use later in the day, you would not want to mix it in liquid, but leave it in powder form so the ingredients wouldn't break down or denature.

What's missing?

You may notice I left out a lot of popular ingredients found in many of these NO2 pre/during/post workout blends like BCAAs, Ribose [15,16], and Glutamine [17,18].  I still feel like the scientific evidence on these is very sketchy.  BCAAs may be a good idea, but their expense puts them at a disadvantage.  Ribose is basically just fancy and more expensive sugar, and we know from many, many studies that glutamine just simply is not orally bioavailable and never makes it into skeletal muscle tissue, making it a total waste of money.  I also didn't include any fancy or exotic herbs that may act as stimulants, nootropics, or insulin stimulating agents.  Although some of them may be advantageous, it's impossible to know what the proper dosage is and find it in a cheap enough form to buy in bulk and add it into our blend.  Not to mention flavoring a lot of these herbs is going to require some very fancy concoctions -- more so than Koolaid would cover up.  In reality, they are probably also not necessary and a lot of times just added on the ingredients list in a proprietary blend, so you, the consumer have no idea how much you're getting and whether or not it's even in a worthwhile amount.  Basically, it's a gimmick.  Still, you could always use any stimulant product you prefer in place of the caffeine, it's up to you.

The Home Made NO2 Cocktail

This blend should have all the main ingredients all the other fancy and more expensive NO2/preworkout blends on the market have, with real working ingredients that are actually scientifically shown to effect strength, body composition, endurance, energy, and stamina.   The ingredients here may even be more abundant than you are getting in one of the marketed blends since, as mentioned, all the ingredients are listed in a proprietary fashion not giving you a clear picture of what you are taking and in what amounts.

You can drink it before, during or after your workout -- although I believe that before or during would be optimal.  So, here are the ingredients you want in the proportions I recommend.  However, you are more than welcome to alter them to suit your needs and tastes.  You can increase the dosage of Beta Alanine beyond 1g if you are comfortable doing so.  Many users report an unpleasant tingling sensation in dosages beyond 20mg/kg (which would be approximately 1.6g for 180lb person). [13]
  • 5g Creatine monohydrate
  • 5g Arginine-alpha-ketoglutarate (AAKG)
  • 20g Dextrose
  • 1g Beta Alanine
  • 2g Citrulline Malate
  • 2g Taurine
  • 50mg Caffeine
Mix into 16-32oz of water (with the exception of the caffeine tablet).  Add Koolaid powder and Splenda to your liking.  The dextrose will already be sweet, so you may want more or less depending on the flavor.  You may want to use a whole packet of Koolaid or more depending on the flavor of some of these amino acids, but start off small and decide for yourself.  Some flavors of Koolaid may work to mask certain unpleasant flavors with Tropical Punch probably being the most masking, but again, this is personal preference.
