Steroids work better by duration rather than large amounts over a shorter period of time.
If you intend taking steroids and are serious, 2 or 3 cycles a year is a waste, may as well stay on rather than constantly fucking around up and down and PCT.
Your body is not going to respond better to 250mg if you have been on 500mg before even if it was years ago. The guy is not going to get the same gains.How? He has had a way higher test level in the past so how would 250mg improve him from when he first used? I think staying on all year is what most people do but I think the body should take at least a 2 month detox phase maybe 3 months. I will agree most ignore that and stay on all year. You constantly have to fuck around and raise the dose and switch compounds to keep your body changing.
using Test at one dose all year is pointless if you are a bodybuilder it's fine if you are a HRT patient but not if your a bodybuilder.
if your a bodybuilder you have to constantly adjust doses and add compounds,drop compounds it can get tricky sometimes if you do it right, especially when you add in HGH and insulin and other peptides and anchileries. This is why the best bodybuilders hire people to help them.
