Testosterone Phenylpropionate is a short ester attached to the Testosterone hormone. This means it takes your body the least amount of time to rid itself of the ester and release the parent hormone into the body. Due to its short active life, Testosterone Phenylpropionate typically needs to be injected every other day at a minimum. Anecdotally, Testosterone Phenylpropionate causes the least side effects and the least bloating; these side effects usually subside very quickly when use is ceased. Testosterone is responsible for promoting health and well-being through enhanced libido, energy, immunity, increased fat loss, gaining and maintaining lean muscle mass, preventing Osteoporosis (loss of bone density) and possible protection against heart disease. Testosterone Phenylpropionate has a release time of between 3-4 days. It is typically injected once every other day, though some users opt for 3 times per week frequency as well. Average dosages are around 600mg per week.
