Testosterone propionate is an oil based steroid with an propionate ester which will cause the steroid to be released from the injection site over the duration of a few days. This is different then the likes of testosterone enanthate which is much more slow acting compared to the propionate ester, which requires much more frequent injections to make sure blood concentrations remain stable. Injections every day, or every other day is the normal practice with testosterone propionate. The greater volume of injections needed when using testosterone propionate is not likeable for some users, either because of their circumstances, or because of the build up of scar tissue and therefore the need for more injection sites to rotate to avoid scar tissue build up. Testosterone propionate can be also a sore shot, and result in fever like symptoms for a couple of days.
A common dose for testosterone propionate is 50-100mg each or every other day. This gives a weekly figure of 350mg-700mg. Propionate is commonly used during cutting phrases, along with other non-aromatising steroids such as winstrol or primobolan. Also very effective is combining the propionate with a non-aromatising androgen such as trenbolone, which would bring about a very hard defined look. Adding more androgenic steroids to the propionate will obviously result in more pronounced androgen related side effects.
