i just did 6 weeks of 100 mg every day of testopin 100, and dropped it to 100 mg every other day and have been on it for bout 8 weeks now... that with 400 mg of deca dropped to 200 mg after six weeks. Great strength gains, I went from 175 lbs to 190 lbs, got puffy nips so I cut the dosages in half, still getting stronger, lost some water. At 5'7" 190 lbs, with little retention i'm looking sick. Great stuff!
I shouldn't matter if it hurts. Inject in the muscle group you're training that day and pump the fuck out of it. It hurts so good.
