Hey guys,
My friend from the gym is starting a cycle soon too as he competes in bodybuilding, however, he's not going to take an AI. He says that by taking HCG it will take care of the estrogen effects. He'll be on test 400, Tren Acetate and Dianobol. I thought HCG was only used during a cycle to help replace LH and protect against Testicular Atrophy. He said he only needs HCG or an AI, not both. Should he not also be taking an AI, or am I wrong?
