So I'm relatively new to the forums, and I just wanted to ask some more experienced people a quick question. I hear that once you hop on AAS, that your natural test level will never be the same even if you do PCT correctly. Now I can understand this after years of heavy use, but if I were to only do a couple light cycles, is this really possible?? I'm only 21, and I don't think I'm ready for gear yet, but I intend on doing a test only cycle at 300-400 mg per week at some point in the next few years once I milk out the rest of my natty gains. Also are the risks of infertility a real thing or is that only with the pros who do grams of stuff year round? Sorry In advance if these are stupid questions.
