When this long-acting version of testosterone is injected, it becomes stored in what is known as a depot in the body, and slowly released over a short period of time. Peaking within 1-2 days after injection, the testosterone is then steadily released over the next 12 days and completely tapers out after approximately 3 weeks.
As with all testosterone products it has a strong anabolic activity, with a pronounced androgenic component. Thus it can provide significant gains in strength and muscle mass, as well a noticeable increase in libido. An added benefit, with all testosterone products is the relief of tendon pain, faster recuperation and an increase in the level and duration of physical output due to the oxygen rich blood along with an increase of red blood cells. Although when taken at reasonable dosages aromatisation should not be a problem, some patients may wish to use an anti-estrogen, this case a low dosage of Tamoxifen Citrate or Mesterolone would be appropriate.
The use of HCG (Human Chorionic Gonadotropin) in addition to Clomiphene Citrate and Tamoxifen Citrate may also be beneficial at the conclusion of use in order to ensure balance in the hormone system.
Testosterone Cypionate is the most commonly prescribed form of testosterone in the United States of America. In fact, it is a bit of a rare find outside of the USA, with most places in the world deferring to the very similar Testosterone Enanthate.
In truth, I’ve used both and find no difference at all between the two. Testosterone Cypionate is identical with regards to results to any long acting testosterone. In the original Underground Steroid Handbook, Dan Duchaine said that users could feel more “kick” from this form over Enanthate, but I honestly haven’t found that to be true personally.
The prime advantage of this product is the fact that it can be injected once per week and it gives some very good gains in strength and size. I would bet that many careers in bodybuilding and athletics were built with the long term use of this drug. I’ve used it at doses of 250-2,000 mg per week, and found that the best gains versus side effects are probably had somewhere below the 750 mg/week mark. Of course this is far below what many competitors in the upper ranks of bodybuilding use, but for the average (recreational) bodybuilder or athlete, the side effects above this dose do not constitute an acceptable trade off for the gains.
