ive talked about primo countless times... its my favorite steroid... clean, dry, continuous gains throughout... little to no sides... it can be hard on your hairline if your prone to it but other than that, you wont see anything aside from smaller amounts of suppression.. its very very very clean and you feel great on it... its not going to provide 15lbs of weight or anything like that, but its clean as can be and you will feel great the entire time with it...
