Increased recovery
Increased growth of both muscles and tendons
Reduced body fat
Increased collagen synthesis for healthy joints
Increased strength
Increased injury resistance
Able to handle more volume in a training session
Improved ability to maintain pace

I won't argue all your points but one I want your opinion on the most, increased growth of tendons through steroid use.

Something I just pulled from another board regarding steroids and tendons. What do you make of the article tychver?. One sentence remarks: "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".

Steroids and tendons.
 
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.

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

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.





Yeah. It's scary enough the Alberto Contador's excuse for clenbuterol was seriously fucking plausable.

+1.

Pharmador should have received a 2 year ban. I'm a huge cycling fan & the UCI is corrupt from top to bottom. It's a complete joke.

Having just done a google search, I'm hearing so many stories of tendon ruptures following steroid usage?.

much longer/better post than mine but thats what i was saying about winstrol...it makes your tendons brittle

When It Comes to Building Tendons, Not All Steroids are Created Equal

Stimulation of collagen synthesis by the anabolic steroid stanozolol.

Researchers: Falanga V, Greenberg AS, Zhou L, Ochoa SM, Roberts AB, Falabella A, Yamaguchi Y; University of Miami School of Medicine, Department of Dermatology, Miami, Veterans Affairs Medical Center, Florida, USA.

Source: J Invest Dermatol 1998 Dec;111(6):1193-7

Summary: In this report, we measured the effect of the anabolic steroid stanozolol on cell replication and collagen synthesis in cultures of adult human dermal fibroblasts. Stanozolol (0.625-5 micrograms per ml) had no effect on fibroblast replication and cell viability but enhanced collagen synthesis in a dose-dependent manner. Stanozolol also increased (by 2-fold) the mRNA levels of alpha1 (I) and alpha1 (III) procollagen and, to a similar extent, upregulated transforming growth factor-beta1 (TGF-beta1) mRNA and peptide levels. There was no stimulation of collagen synthesis by testosterone. The stimulatory effects of stanozolol on collagen synthesis were blocked by a TGF-beta1 anti-sense oligonucleotide, by antibodies to TGF-beta, and in dermal fibroblast cultures derived from TGF-beta-1 knockout mice. We conclude that collagen synthesis is increased by the anabolic steroid stanozolol and that, for the most part, this effect is due to TGF-beta-1. These findings point to a novel mechanism of action of anabolic steroids.

Discussion: I must first acknowledge that the commonly held belief is that anabolic steroids predispose an athlete to tendon rupture. This conclusion is drawn from animal studies showing that some steroids produce a larger, stiffer tendon in rats and that these steroid-induced tendons "fail" before the tendons from the control animals. The term fail refers to the breaking point.

The interesting thing about the present study is that the steroid stanozolol (Winstrol) had a different effect than testosterone. If you are a regular reader of MESO-Rx you should be well aware that not all steroids act in the same manner. And that because of subtle differences in there molecular structure they are able to elicit different responses. For example, Deca seems to act primarily through the androgen receptor (AR) where as Dianabol has effects beyond those associated with the AR.

Because synthetic steroids have differ in their chemical properties it should not be surprising that testosterone did not have the same effect as Winstrol. Winstrol increased collagen synthesis as opposed to testosterone which did not in this study. Interpreting the results of this study are more difficult than simply describing them. Other researchers have suggested that steroids cause a rapid increase in protein synthesis within tendon fibroblasts which results in fibroids or fibrous nodules within the tendon (Michna,1988). These fibroids alter the mechanical properties of the tendon perhaps predisposing it to rupture. It is also noted that during short term use of steroids there is an alteration in the alignment of collagen fibers which may also lead to rupture. Interestingly these alterations in collagen metabolism are transient with markers of collagen turnover returning more or less to baseline after 3-4 weeks of steroid administration (Karpakka,1992). These same researchers noted that low dose anabolics effect primarily muscle collagenous tissue with tendon being effected only at higher doses (i.e. 5 times the therapeutic dose) which would more closely represent what is needed by bodybuilders to put on mass.

The question remains, dose this mean that Winstrol will actually help prevent tendon injury or will it lead to bigger yet stiffer tendons prone to injury? It is difficult to take animal research and extrapolate the results to humans. Stanozolol is used therapeutically in humans to treat a variety of connective tissue and vascular disorders and its clinical effects suggest that it can modulate connective tissue breakdown in people. Despite being labeled as "ineffective" by many bodybuilders it is very popular among athletes. As with most hormones, dosage plays a role in what effects are seen, be they positive or negative. Hopefully future studies will shed light on the therapeutic effects of different steroids on tendons in humans.

philray is natty. He has progress pics of himself since he started lifting... looks natty, no huge jumps. He's also the oldest and has been working out the longest.

Babo claims he's natty. Skeptical though because he blew up just like zyzz/chestbrah in the same time period and they are open about using gear. Babo says his grandpa or something was some successful bodybuilder or something though so he claims he has very good genetics.

Manlets ftw

None of them are natty. And all of them "look natty". None of them have impressive physiques that you couldn't get naturally.

can we have a rule on this forum to never use the term "natty" again? just such a bro douche bag thing to say

basically, that study shows that winstrol is used to IMPROVE connective tissue in certain cases and you cant draw human conclusions based on rat research.  So basically, its just showing how the idiots who go around saying "winstrol causes tendon damage" got their flawed info from, basically.

Other researchers have suggested that steroids cause a rapid increase in protein synthesis within tendon fibroblasts which results in fibroids or fibrous nodules within the tendon (Michna,1988). These fibroids alter the mechanical properties of the tendon perhaps predisposing it to rupture. It is also noted that during short term use of steroids there is an alteration in the alignment of collagen fibers which may also lead to rupture. Interestingly these alterations in collagen metabolism are transient with markers of collagen turnover returning more or less to baseline after 3-4 weeks of steroid administration (Karpakka,1992). These same researchers noted that low dose anabolics effect primarily muscle collagenous tissue with tendon being effected only at higher doses (i.e. 5 times the therapeutic dose) which would more closely represent what is needed by bodybuilders to put on mass.

The question remains, dose this mean that Winstrol will actually help prevent tendon injury or will it lead to bigger yet stiffer tendons prone to injury? It is difficult to take animal research and extrapolate the results to humans. Stanozolol is used therapeutically in humans to treat a variety of connective tissue and vascular disorders and its clinical effects suggest that it can modulate connective tissue breakdown in people. Despite being labeled as "ineffective" by many bodybuilders it is very popular among athletes. As with most hormones, dosage plays a role in what effects are seen, be they positive or negative. Hopefully future studies will shed light on the therapeutic effects of different steroids on tendons in humans.

so basically this study says it doesn't know







basically, that study shows that winstrol is used to IMPROVE connective tissue in certain cases and you cant draw human conclusions based on rat research.  So basically, its just showing how the idiots who go around saying "winstrol causes tendon damage" got their flawed info from, basically.

i guess it's all acedemic anyways since i'm never going to use the stuff

Having just done a google search, I'm hearing so many stories of tendon ruptures following steroid usage?.

Tendon strength is actually improved at moderate doses of testosterone but like any good thing, far too much of it is actually harmful. Testosterone replacement therapy generally uses around 100mg of testosterone cypionate/enathalate a week to achieve mid-high normal testosterone serum level. Recreational bodybuilders  run 400-500mg of the same injectable testosterone a week for 8-12 weeks which results in rapid strength gains along with inhibited collagen synthesis. When you combine that with the fact that they've often never lifted properly before and their bodies are not well adapted to the stress of repeatedly lifting heavy you have a disaster waiting to happen. But you wanna look jacked for the bitchez bro.

And to add to that, they used animals as opposed to humans to conduct the research. I can't really take anything away from that.

When you combine that with the fact that they've often never lifted properly before and their bodies are not well adapted to the stress of repeatedly lifting heavy you have a disaster waiting to happen. But you wanna look jacked for the bitchez bro.

Not too jacked though as the quote below implies:

Would that also apply to you JC if you was a professional athlete?.
