Im 22 yrs old, 5'8", 165lbs, 12% body fat. very stacked for my smaller build. I have been training very hard for 2 and a half years now and decided to try steroids for the first time. I have deca on the way as i have read that it is the safest route. I have enough to do 300mg a week for 7 weeks and can get more if i need to. my PCT will be nolvadex. i want to know if 300mg a week for 7 weeks will be enough for me to see gains and how much of those gains i will keep. and if nolvadex is enough for PCT. is there anything else i should take during my cycle to keep the sexual side effects at bay? my main concern is sexual side effects, i want to avoid them as much as possible but have my heart set on using deca. any advice would be appreciated. my goal is to go up in weight slightly, but i am more focused on strength, and not losing my good run time.
