I used puritysourcelabs sustanon and ran it 500mgs a week for 16 weeks
My results were Outstanding
I started out at 5'7 and 180 lb. by the end of the cycle I was up close to 200 lb. also I had some Incredible strength improvements. I went from the second weakest dude in my group that I train with to the strongest in a matter of 16 weeks
my only one complaint was the post injection pain. other than that great cycle
