ok let me start by saying i have never taken any aas before but have ran a 6 week of bold and a 3 week of SD/tren. im looking to gain about 15 lbs of muscle and i want to get alot stronger as well while staying pretty lean. a buddy of mine has 50mg yellow winstrol tabs. is this the best option for my goals? also, how long should it be ran and at what dosage?
