Test Prop 100 - Testosterone Propionate - ISIS Pharma


This is an esterified form of the base steroid Testosterone, much like Enanthate, Cypionate and Sustanon 250.

It's a superlipophillic, oil-based injectable that slows the release of the steroid into the blood stream. But compared to Enanthate and Cypionate, it is a very short ester however it is still released relatively fast and as such more frequent injections are needed. Levels will peak after 24-36 hours and begin tapering from that point. The timespan between injections is about 3 days. Most athletes will opt to inject 50-100mg every day to every other day.

It's not the most user-friendly steroid of them all. Frequent injections can be painful to begin with, to a point where users will begin scouting for different locations to stick the needle in order to not aggravate the same spots. The injection-site can become irritated and swell, and sometimes give incredible itches or soreness when touched. It can cause damage to the skin and underlying tissue can cause some cosmetic problems if it becomes repetitive. Subcutaneously, balls of fat or tissue can build up. In most cases these need to be surgically removed (rotating is wise).

As with Enanthate and Cypionate, a long-acting ester requires some skill with ancillary drugs and familiarity with post-cycle protocol since simple discontinuation will not put a halt to all the problems. In that respect, for those who do not master ancillaries and post-cycle therapy, propionate is perhaps a better product to start off with. Levels of androgens and estrogens will drop within 2-4 days of discontinuation, effectively halting or reducing any occurring side-effects. Nonetheless, this is a Testosterone with a high risk of side-effects (the characteristics of Testosterone do not change despite the ester, which is just a carrier) so the use of Nolvadex/Proviron/Arimidex and so forth is highly advised if you plan to see a cycle through.

What is of note with Propionate, is that users have successfully incorporated it into cutting cycles as well. Especially people who tend to lose a lot of mass normally during extreme diet phases. By injecting every two or three days and using only 50-75 mg each time, no notable water builds up (or at least none that can't be fixed with Proviron, Arimidex or Winstrol) and no fat is deposited, thus allowing a user to stay relatively lean. This type of Testosterone can be used to keep gaining or retaining mass until 2-3 weeks out of contest time with relatively little difficulty. Although most will choose to add Proviron (50-100 mg/day) out of precaution. Its best use is in the bulking phases to pack on mass.

Testosterone is not the king of the hill of all mass-builders for nothing.
