While injecting test increases protein synthesis by roughly 50 times, depending on dose and time, most bodybuilders forget that it will reduce collagen synthesis by more than 50% -- more like 80%, giving you the collagen synthesis rate of a senior citizen. Since collagen makes up tendons, bros are very prone to injury if they continue to lift very heavy, unless they cycle off T and let their collagen synthesis get back to normal. It's like having the skeletal muscle of a gorilla with the tendons of a very old man.
Winstrol increases collagen synthesis. It will give you bigger tendons. However, your body compensates for this by making them more brittle, weaker, and more prone to injury. I can't tell you how many bros work out anaerobically and become injured while on winstrol. Guys who lift in the 1-5 rep range while on winstrol, to baseball players who sprint all out from a stationary position -- winstrol should be the LAST drug they choose. Most of them like winstrol because they don't get the weight gain from it but it is very detrimental to bros who train for any sport anaerobically. Tendons tear easily on it.
Also, the drugs I mention increase collagen synthesis while also increasing collagen cross-linking integrity, making for a much stronger tendon.
Winstrol, on the other hand, will dramatically increase collagen syn, but ironically it decreases collagen cross-linking integrity, thus making a much weaker tendon.
You can plan a cycle of AAS which will increase collagen synthesis and skeletal muscle growth at the same time. The key is the drug(s) you choose.
Deca, Equipoise, Anavar, and Primobolan will ALL increase skeletal muscle while at the same time dramatically increase collagen syn and bone mass and density, leaving you with a substantially reduced chance of becoming injured than if you choose to use AAS like sus, cyp, or enth.
While testosterone will increase bone mass and density, even at supra-physiological levels, the result is weaker tendons due to inhibition of collagen syn.
