So i haven't done a cycle in 3 years, I been lifting naturally for a long time now making gains, i plan to start Decca/prop in a few weeks, should i take a low dosage as if i never done this before or will my test receptors react like ive done this before and require bigger dosages? last cycle was 600mg of decca a week along with 2 cc's of T-4 a week for 10 weeks but once again that was 3 years ago. I have a feeling this might be like taking a cycle for the first time again (hopefully) can i get some input? thanks..
