Your Key To Success: Half Life of Testosterone Cypionate and How to Apply It
Chemical Structure and Half Life of Testosterone Cypionate
Testosterone cypionate belongs to androgens, testosterone dissolved in oil with cyclopentylpropionate ether attached through a 17-beta hydroxyl group (17b-hydroxy-androst-4-en-3-one), its half-life in the body is approximately 6-8 days (full life work 15-16 days), chemical formula C8H14O2. Half life of testosterone cypionate strongly resembles by its action on testosterone enanthate. These forms of testosterone support an increased level of testosterone for 14 days, despite this, they speak of a higher water retention by cypionate ester. It is likely that enanthate is slightly better in the issue of testosterone release, due to the fact that this ether is lighter by one carbon atom than cypionate (ether is calculated in terms of steroids per mg). It should be noted that the difference is so small that it is not even noticeable (it is quite possible, since several mg per injection is injected, the actual concentration of the active substance of testosterone is 70 mg, the remaining 30 mg is cypionate ester).
At the beginning of the 50s, testosterone cypionate first appeared on the western market, and was brought out by Pharmacia & Upjohn. At first, the drug was not widely known; it can be said that it was taken as a substitute for testosterone enanthate in the US market. If you compare these drugs, they have a small difference – cypionate is not so often the cause of local irritation. Testosterone cypionate is used in a clinical setting to treat men with low androgen levels, which results in reduced potency, loss of vigor. In the 1960s, the drug was used to improve bone structure and to treat menorrhagia and fight osteoporosis. In addition, testosterone cypionate was used as a drug that stimulates spermatogenesis, by 6-10 weeks inhibition of spermatogenesis with doses of 200 mg per 7 days, followed by recovery. By the end of the 1970s, the method of using it was revised, it was no longer used as a means of infertility. Testosterone cypionate is among the most common drugs on the US market, and beyond, including Canada, Australia, Spain, Brazil and Southern Africa.

Reduces the production of luteotropic and follicle-stimulating hormones. Testosterone belongs to the antagonists of female sex hormones – estrogen. The drug has an antitumor effect in breast tumors in women. It has an anabolic effect, it is manifested in the stimulation of protein synthesis, a decrease in fat deposits, a delay in the body of potassium, phosphorus, sulfur necessary for protein synthesis, increased calcium fixation in bones and an increase in muscle mass. If in the diet of a person taking the drug enough protein, it contributes to the development of erythropoietin.
