Testosterone Propionate Description
The propionate ester is one of the shortest esters used in any steroid preparation, and it’s one of the most popular versions of testosterone ever used. When used alone, testosterone propionate should be injected every other day . In the sustanon 250 formula, injections can be done weekly since the isocaproate and phenylpropionate ester are just starting their full release as the propionate ester wears out.
The reported half-life of propionate is around 4.5 days, but it’s believed to be closer to 3 days by many bodybuilders. This might have something to do with the way the ester is cleaved off by different men with different health levels.
Basically, the propionate ester is the base of the sustanon formula. It’s added as a TRT drug because it gives men with the usual TRT symptoms an immediate boost. Think of it this way, after years of low libido, depression and weight gain caused by low testosterone levels, you feel great within days of your first sustanon injection. Therefore, you can call the propionate addition to the sustanon TRT formula a psychological boost more than anything.
