Testosterone Phenylpropionate lasts for 4-5 days at a time. Testosterone is responsible for the production of hormones in male’s testes. It can be injected for maximum 2 times a week. It increases energy and increases aft losses, increasing muscle strength and also saves from heart diseases. Every day you can consume around 200 mg a day with an effective result but should not be consumed more than weeks at a stretch as it can lead a hair problem or liver problem. Although water retention is low through this medicine but not negligible so you need to be careful while using it. Injecting it after 3-4 day will be the best idea.
