Testosterone Suspension is the oldest steroid ever created. Basically it is pure testosterone without any ester attached to it. This has its disadvantages because without any ester the testosterone won’t last very long in the body and will probably need to be injected every day, even multiple times a day. The major advantage of pure testosterone is that users get exactly the amount of testosterone that the vial says is there and because of testosterone suspension’s pure anabolic/androgenic ratio of 1:1, it is the most potent testosterone you can put in your body by weight available.

Testosterone is the male sex hormone responsible for many of the physical and emotional traits of men. It creates the deeper voices, sex drive, aggression and, of coarse, larger muscles in men. Testosterone makes the muscles retain more nitrogen, which in turn makes the muscle synthesize proteins better, producing larger muscles.

The downside to testosterone steroids is that they aromatize, or turn into estrogen, in the body. When the body has too much estrogen it begins to take on female characteristics – gynocomastia, water retention, fat gain, loss of sex drive and testicular shrinkage are all most certain side effects of taking testosterone and letting it aromatize in the body.

Testosterone suspension is an injectable preparation containing testosterone (no ester) in a water base. Since testosterone is not highly water soluble, the steroid will noticeably separate from the solution when the vial is left to sit. A quick shake will put the drug back into suspension, at least temporarily, so that it can be withdrawn in a consistent dosage. Although it may contain testosterone without the benefit of an ester, and contrary to popular belief, the microcrystal design of this injectable will sustain an elevated testosterone release for 2-3 days. Clearly the suspension we see today is not the basic water plus testosterone design used in the 1940?s. And since the drug will not leave circulation in a matter of hours, it is obviously useful.

Among bodybuilders, ?suspension? is known to be an extremely potent mass agent. It is often ranked as the most powerful injectable steroid available, resulting in an incredibly rapid gain of muscle mass and strength. This is largely due to the very fast action of this drug, as the water-based steroid will begin to enter the blood stream almost immediately after an injection is given. Unlike longer esters such as enanthate or cypionate which take weeks for blood levels to reach maximiun theraputic levels, with suspension it is just a matter of days. Clearly the anabolic effect of this testosterone will be realized much more quickly than we would expect with an oil based (esterified) preparation.

It is also important to remember that 100mg of a testosterone ester is not equivalent to 100mg testosterone of pure testosterone (as in suspension). When an ester is present, its weight is obviously included in the preparation?s milligram total. Looking at Testosterone enanthate, 100mg of this compound equates to only 72mg of raw testosterone. So the bodybuilder who uses 400mg of enanthate weekly is really getting about 288mg of testosterone into his body each week. This is clearly a great increase over the endogenous testosterone level of the average male, which is in the range of 2.5 to 11 mg per day. But the general point is that during a cycle of Testosterone suspension we will often see a much more dramatic intake of testosterone on average than is typically utilized with oils. Following common advice, the athlete will commonly inject a full 100mg of testosterone daily, a total of 700 milligrams per week. This is up to 40 times the amount produced by a normal male. Those who have attempted such a cycle are rarely disappointed with the results, as such heavy doses of this hormone will produce nothing less than a dramatic weight gain.

The most popular practice with Testosterone suspension is to inject the drug every day. The dosage will vary greatly depending on the needs of the individual, but is most often in the range of 50mg to 100mg per shot. In most cases the results will be amazing. Although some users will complain about discomfort when injecting water-based steroids, suspension is usually well tolerated.

As would be expected with a strong androgen, suspension can produce a number of unpleasant side effects. As with any testosterone product there will be a high rate of estrogen conversion. Estrogen levels in fact build very quickly with Testosterone suspension, which is probably the worst testosterone to use when wishing to avoid water bloat. Gynecomastia can also develop very quickly during a cycle, and in many cases this drug will be intolerable without additionally taking an anti-estrogen. A combination of Nolvadex and Proviron is an effective way to avoid experiencing such side effects, and is often taken from the onset of a cycle in order to prevent such occurrences before they become a problem. Sensitive individuals may find an investment in the anti-aromatase Arimidex, Femara, or Aromasin to be wiser. These anti-aromatase drugs are much more effective at controlling estrogen. It is also important that the athlete monitor blood pressure and kidney functions closely during a heavy cycle, as water retention becomes more pronounced. Although testosterone puts very little strain on the liver, this drug can be harsh to the kidneys at higher dosages. Of course if the athlete is encountering noticeably high blood pressure or trouble urinating (pain or darkening of the urine), the cycle should probably be discontinued and the doctor paid a visit. Since it converts to DHT. one can therefore expect to endure oily skin, acne, increased aggression and body/facial hair growth during a typical cycle. Propecia/Proscar would be a good idea for those predisposed to male pattern baldness, as suspension is known to aggravate this condition quite easily. Men with an existing hair loss problem may actually prefer to stay far away from this steroid altogether, finding it to be just to strong an item to take risks with. The slower acting oil based injectables like enanthate or cypionate would be a much better place to start with if one still desires to use an injectable testosterone.

Endogenous testosterone production will be quickly and efficiently reduced when using suspension. This can often reach the point of severe testicular shrinkage (atrophy). Some athletes will periodically take HCG while on a cycle, in order to keep this effect to a minimum. Even if no such drug is used during, a combination of HCG and Clornid/Nolvadex should always be used as the cycle is discontinued.

Overall, suspension is an extremely powerful drug, but also one that is prone to causing many side effects. Those looking for only a potent mass agent need not look no further, Suspension will certainly get the job done.

Have u any experience with this? Since its the most potent, what would a pct plan look like if one was to dose 700mg a week for 10wks?

I would not advise a Test Suspension cycle all by itself for someone. Even someone with years of cycling under their belts. Suspension comes with the harshest side effects of any of the Testosterones. I made that mistake on my last cycle. If you chose to use Suspension have your HCG and clomid on hand and begin at the conclusion of your cycle and take your nolvadex from day 1. Get ready for high blood pressure, water retention and acne. I would rather go with 700mg of Test E or Test Cyp and avoid these sides. YOU WILL SUFFER AT LEAST ONE OF THESE IF YOU CHOSE TO USE SUSPENSION, AND MORE LIKELY ALL THREE

by Anthony Roberts - Testosterone Suspension does not have an ester attached, making it a "pure" version of the parent hormone, Testosterone. Therefore, there is no ester to be accounted for in the weight. This means 100 mg of testosterone suspension contains 100 mg of the steroid. This makes it the most potent forms of Testosterone available. Gains come quicker and side effects much more possible with such a strong version of this hormone.

Because it does not need to break down an attached ester (like other esterified versions) the hormone is effective immediately when administered. The users testosterone levels will be raised for only 2-3 days (at most) after injection and the steroid should be administered daily. This testosterone is dissolved in water typically, not oil like most of the other esterified versions making it more readily available in the body.


Testosterone Suspension was the first anabolic steroid ever developed, in the 1930’s. It has been used as the most potent mass builder for decades. It was responsible for the Russian dominance in weightlifting not long after.

In the United States, a very short acting version of Testosterone Suspension is available. The brand name for aqueous testosterone suspension is "Aquaviron." There are only a few overseas versions available, including, the most popular, Testosus, which is manufactured in Australia. Testosus was recently replaced by a Mexican brand known as Anabolic-TS, which is the same steroid now sold under the label Grupo Comercial Tarasco (a Mexican distributor for Jurox). Univet Uni-test is the Canadian version of Testosterone Suspension. Many underground labs also suspend this variance of Testosterone (which is usually suspended in water) in propylene glycol or oil, making it a much more painful injection.

Steroid Action

The key role of Testosterone include: promoting health and well-being through enhanced libido, energy, immunity, increased fat loss, gaining and maintaining lean muscle mass, preventing Osteoporosis (loss of bone density) and possible protection against heart disease. Testosterone is also responsible for normal growth and development of male sex organs and maintenance of secondary sex characteristics. Secondary sex characteristics are specific traits that separate the two sexes, but are not directly part of the reproductive system, for example: chest and facial hair, a distinguished jaw line, broad shoulders and increased muscle mass. Testosterone binds to the Androgen Receptors (AR), which thus causes accelerated muscle gain, fat loss, and muscle repair and growth. These mechanisms are stimulated by activation of the Androgen Receptors (either directly or as DHT)

Testosterone Suspension is the best-known potential mass builder, yet must be used with caution due its high risk of side effects. Often these effects are the result of the hormone being so readily converted with in the human body to a more androgenic form of itself, Dihydrotestosterone (DHT). Through aromatization, testosterone can also in-turn form estrogen (the female sex hormone). These potential side effects include: water retention, bloating, fat gain, gynecomastia (formation of breast tissue in males) and conversion to DHT (dihydrotestosterone) as well. Also, supplementing Testosterone will result in the shutting down of the body's natural production of the hormone. The severity of these effects depends mostly on the levels and duration of circulating free testosterone. Testosterone's anabolic/androgenic effects are dependant upon dosage, the higher the dose the higher the muscle building effect. Testosterone promotes aggressive and dominant behavior. Effective doses range from 350-1000 mg per week (50-140 mg/day).

Technical Data

Users of Testosterone Suspension reported rapid muscle growth and water retention. Increased aggression was also commonly reported with use of this specific type of Testosterone. Users found that Testosterone Suspension provided the best results when it was run for at least 8 weeks. More experienced users found they had better results when extending their cycle slightly longer (1). While using this hormone, endurance and strength increases were reported while following an intense training and workout routine (1-2).

As with all of the Testosterones, the most common report by subjects using testosterone was immense gains in strength (3). Alterations in size, shape, and appearance of the muscle were also reported (4). There was roughly a 15% gain in Lean Body Mass from 20 weeks of 600 mg/week of Testosterone therapy. (5)

User Notes

Most of the preceding information on testosterone suspension was actually about testosterone in general or other esters. Why? Well, medically, there is nobody using testosterone suspension anymore. It’s considered a bit of an ugly drug by most of the medical community. It’s just straight testosterone suspended in water (or sometimes, with certain underground preparations in oil). As a result, it needs to be injected at least once a day, with some athletes preferring to inject it twice a day.

It has a reputation for being used as a pre-game (or pre-workout) stimulant to increase aggression. I can attest to it being pretty useful for this purpose, actually, as can many pre-contest bodybuilders.

In the end, though, not many people will base a cycle around testosterone suspension - it’s uncomfortable to inject and leaves some pretty odd looking bumps in the muscle while it’s still there.

Threw in a lil more that i was reading. I know I like to read alot about any compound before i run it. Pretty much the same info in different words lol!

06-11-2011, 06:18 PM
Can it be used successfully for short say 5week cycles?
What about as a pre workout boost?

06-12-2011, 04:53 AM
Reading about it I would say yes since it so fast acting. But i have no personal experience with it. I wanna try it out ppl say alot more sides but its very tempting. I love the ON feeling of test just hate that it takes so long. I think with some Adex or even letro depending on how Estro sensitive you are it would be great. Test Susp. with a strong oral like D-Bol or A bombs would be awesome and even throw some Deca in there and ohhh man. Idk more research on this is needed for me
