i am 20 .Training for a year and a half now and planning to go on a test e only cycle. However, when i went through multiple webbies, somem of the injectable cycles needs HCG for pct while some others dosent can you tell me why. Can you guys gimmie some ideas of a pct that you guys have done on yourselves and with great results in terms of not having any sides and retaining the most amount of muscles.
