my cycle was for 10 weeks at 500mg with hemos at 50-75-100-75-50 from weeks 1-5. i gained 17 pounds only in the first 5 weeks stopped gaining after the abombs and actually lost 12 pounds only 4 weeks after which means to me that i gained nothing from the durateston and i did do clomids after. my friends cycle was primo only 400mg then decided to do sust everyday for 2 weeks which would amount to 5-6 weeks because of the esters as you very well know, he's in week 6 and only up 5 pounds and this is his second cycle so he should be growing well off this. all i have to say is that i didn't like it i felt like i was on 150mg of test, i never felt it kick in and my amps look legit got from reputable source down south. maybe they fake but i just did not like them.
