So I've decided to run some sustanon, and already 10 days in my lifts and endurance have increased significantly. In the past, I had experimented with anavar-only for short time frames. I liked the hardness and vascularity, but never did a cycle with it because oral-only I generally consider to be shit. So anyhow, now that I'm running test I thought it would be good to throw in the anavar to harden up and add to the strength. So a couple days in at 40mg, my veins are popping out more and there is a definite increase in hardness, but for the life of me, I cannot figure out why I lose my pumps, endurance, and strength in the gym. I essentially cannot workout. 1 set and the muscle tears, with no pump, and no stamina. I thought anavar gave great increases in pumps. I can say for sure the anavar is not fake, as I know 2 other people who used it and loved it. This also happens to me if I use winstrol, or halotestin, or anything else that isnt plain testosterone. I have constant aches and pains, as if I'm shut down or something, which goes away as soon as I stop the oral. Does anyone have the slightest clue as to why this happens?
