I found this info when I had my knee replacement surgery, here is a good write up.
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.
To plan a cycle where the goal is to increase skeletal muscle mass/strength while at the same time increase joint/tendon/ligament strength, enough to keep up with the dramatic increase in skeletal muscle, you must choose drugs like Eq, deca, Anavar, or Primo as the base of your cycle. Testosterone and its esters can be added to your cycle to keep levels within a 'normal' physiological range (ie, 100-200 mg/wk) but must not go above this. Since drugs like eq, deca, anavar and primo will reduce endogenous, natural levels of test, these levels may be maintained with exogenous test in the 100-200 mg/wk range. test 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.
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 syn. As you can see, deca is a very good drug at giving you everything you want -- an increase in collagen syn, an increase in skeletal muscle, and increases in bone mass and density. The one thing it does not give you is wood. I didn't know this!
primobolan, @ 5 mg/kg, will increase collagen synthesis by roughly 180% -- less than deca and equipoise but still substantial.
Equipoise @ 3 mg/kg will increase procollagen III by approximately 340% -- slightly better than deca.
Oxandrolone has over a hundred studies documenting its effectiveness at treating patients needing rapid increases in collagen syn to enhance healing.
These drugs have longer half-lives than most other AAS, so this should be considered when timing your post cycle clomid use. Here they are:
deca: 15 days Equipoise: 14 days primobolan: 10.5 days
Anavar has a half-life of only 8 hours so it should not pose a problem.
GH is probably the most remarkable drug at increasing collagen synthesis. It increases collagen syn in a dose dependant manner -- the more you use, the more you will increase collagen syn. It has also demonstrated this ability in short and long term studies. From what I've read, HGH at 6 iu/day increased the collagen deposition rate by around 250% in damaged collagen structures. This result indicates that the increased biomechanical strength of wounds to collagen structures treated with biosynthetic human growth hormone was produced by an increased deposition of collagen in the collagen structures.
Eq, primo, anavar, and deca are all good -- they increase several biomakers of collagen syn -- ie, type III, II, I, procollagen markers. GH just seems to do so most dramatically.
Use of any of these drugs @ supra-physiological levels with a maintenance dose of test will increase collagen syn while at the same time increase skeletal muscle mass. Skeletal muscle mass gains will not be as dramatic as with large testosterone doses but you have to weigh the risk/reward basis for yourself. Also, these drugs do not satisfy the libido like testosterone, but that is not the point of this thread. It is only to demonstrate that you can increase skeletal muscle and collagen syn at the same time with certain AAS -- the decision is up to you.
