right around now....by week 6 you should def be up maybe 10 lbs and have noticeable size increases. Right now you should already see changes in the mirror, no? No sick pumps when lifting and volumization of the muscles? Anyway, week 4-6 is when it's really magical strength and growth wise. I'm just out of week 7 on test e and I'm strong like ox and pretty jacked up. I'm still swelling...
