Winstrol increases tendon size by increasing collagen synthesis but the body makes up for this by making them brittle since it decreases collagen cross-linking integrity . Deca @ 3 mg/kg a week(about 270 mg/wk for a 200 lb male) will increase procollagen III levels by 270% by week 2. Procollagen III is a primary indicator used to determine the rate of collagen synthesis. Even better, Equipoise @ 3 mg/kg will increase procollagen III by approximately 340% -- slightly better than deca. Also, while running winny, it's not a bad idea to keep test @ at 200mg/week or less cause at this dose will not inhibit collagen syn, but paradoxically, will help increase it. It is when exogenous testosterone is used > 200 mg/wk that collagen syn is inhibited.
