Testosterone Propionate has already been profiled so please refer to that write up.
Testosterone Phenylpropionate has a half-life of 4 to 5 days and releases into the blood stream at a rate directly in the middle of the Propionate (short) and Cypionate (long) versions of testosterone. This version of testosterone is very rarely compounded on its own and is usually a perfect ester to put with Propionate and Enanthate/Cypionate because it fills the gap between the release times of the two as in the case of Test Combo 450mg by Ciccone Pharma.
For the purpose of understanding and profiling phenylpropionate we will discuss its characteristics as an individual API. Phenylpropionate on its own usually gets administered twice a week or every third day. It has the usual side effects as all other testosterones. It has a high level of aromatization into estrogen and converts to DHT (dihydrotestosterone) as well. Conversion to estrogen creates as per usual gynecomastia and water retention. Water retention and an increase in blood pressure are also expected. Natural HPTA axis shuts down as soon as it gets administered and natural production of testosterone stops. The severity of the side effects is usually dose related and the higher the dose the more the side effects.
As per all testosterones phenylpropionate will increase muscle size and strength dramatically. It will decrease bodyfat and HDL cholestrol will be lowered by this testosterone.
Testosterone Isocaproate first appeared in one of the most popular and well-known testosterones in the world called Sustanon 250mg. Every bodybuilder or athlete who has ever taken performance enhancing substances would have taken Sustanon before. Isocaproate is very rarely found as a single ester based testosterone compound and is almost always in testosterone mixes.
Isocaproate is a moderate sized ester and fills the role between the phenylpropionate and propionate short esters and the cypionate and enanthate long esters. It plays a vital role in keeping the blood levels stable and through the total compound you receive a total testosterone benefit for a long period of time. The side effects and effects of Isocaproate is exactly the same as all the other testosterone esters.
Testosterone Decanoate the same as Isocaproate first appeared in the very popular testosterone blend called Sustanon 250mg. It is also very seldom offered outside of a blend and is mostly used with a blend of other testosterone esters.
As per other testosterone esters Testosterone Decanoate will cause weight and strength gain, fat loss, libido increase, an increase in IGF-1 levels, red blood count increase and increase in recovery rate from training. The side effects are also the usual shutting down of natural testosterone production (HPTA axis), aromatising to estrogen (the cause of gynocomastia) and dihydrotestosterone respectively. Water retention, high blood pressure and bloating is normal.
Testosterone Decanoate is a long acting ester and carries the Cypionate through to keep the blood levels elevated for up to 4 weeks after administration.
Testosterone Cypionate has already been profiled so please refer to that write up.
To conclude this designer drug – you have five different esters combined from the shortest one being propionate to the longest one being decanoate and they will all release and become active over different time intervals. The goal with combining these different esters in one blend is to elevate the testosterone levels in the blood as fast as possible and keep it as high and as stable as possible over the longest period.
