Did 100mgs/day of test suspension. Did it for 4 weeks,Gained 15lbs . I will do it again but for 8 weeks probably. You really need to be comfortable injecting in just about every muscle though as you will get some pip if you inject to frequently in the same muscle. I rate suspension higher than Tren for size and strength. Take an Ai with it because you will have sides at the dosage I did. And to be honest I can't wait for fall to jump right back in it.
