I see are you taking the test prop daily or eod ? im or sub q sorry for many questions just find the concept intrestingOnly two or three milligrams. This is on top of 6-9 mg of T propionate. I've tried both isolated—e.g. weekly—and daily. Daily stops working after a week or so, but with isolated injections you can at least repeat the cycle indefinitely. I find it pretty interesting that something that should be out of your system in less than a day somehow has relatively long-term effects. Somehow just changing hormone levels has useful effects.
