Testosterones negative impact in collagen synthesis and how to counteract it

Testosterone in high doses have been shown to inhibit collagen synthesis. This is bad not only for skin health but also for joints and tendons, which increase risk of injury. I’ve made some research on this subject, and find the pathways of which high testosterone inhibit collagen synthesis and what we can do about it.


Inhibition of Transforming Growth Factor-Beta (TGF-β) Signaling: Testosterone may interfere with the Transforming Growth Factor-Beta (TGF-β) pathway. TGF-β is a key regulator of collagen synthesis, and disruption of this pathway by excess testosterone may hinder collagen production. To counteract this, vitamin D, C and E, omega 3, curcumin, magnesium, selenium and zinc, may help support the production of TGF-β in the body. Regular exercise has also been shown to positively influence TGF-β levels. Certain strains of probiotics, such as Lactobacillus rhamnosus, Bifidobacterium infantis, Lactobacillus casei, and Lactobacillus plantarum, may also upregulate TGF-β levels.


Regulation of MMPs (Matrix Metalloproteinases): Testosterone can influence the expression and activity of Matrix Metalloproteinases (MMPs), enzymes that degrade collagen and other extracellular matrix components. High testosterone levels may upregulate MMP expression, leading to increased collagen breakdown and decreased synthesis. Compounds that inhibit the activity of matrix metalloproteinases (MMPs) may help prevent this. Some natural MMP inhibitors include green tea, resveratrol, curcumin, quercetin, rhodiola and N-acetylcysteine (NAC). However NAC has also been shown to inhibit TGF-β expression and activity in some contexts. This has led to the hypothesis that NAC may have potential anti-fibrotic effects by mitigating excessive collagen deposition mediated by TGF-β. The impact of NAC on collagen synthesis is likely dependent on the specific cellular and tissue context. Moderate inhibition of TGF-β by NAC may not be an issue but rather help to prevent fibrotic responses, since excessive interference with TGF-β signaling could hinder normal collagen production and tissue repair processes. It’s unclear if these peoperties of NAC is good or bad in the context of supraphysological testosterone levels.


Wnt/β-catenin Pathway: The Wnt/β-catenin signaling pathway is involved in various cellular processes, including collagen synthesis and tissue regeneration. Testosterone may affect the activity of this pathway, leading to alterations in collagen production. Compounds that activate the Wnt/β-catenin signaling pathway, like vitamin D, lithium, certain polyphenols found in green tea and resveratrol, may help promote collagen synthesis. Physical exercise can also help to activate Wnt/β-catenin signaling.


Fibroblast Activation: Testosterone can influence the activation and function of fibroblasts, which are key cells involved in the synthesis of collagen. Changes in fibroblast activity induced by testosterone can impact collagen synthesis in tissues. Supplements that support the activation and function of fibroblasts, such as vitamin C, amino acids (e.g., glycine, proline, lysine), and collagen peptides may aid in collagen production.


Low Progesterone: exogenous testosterone can lower progesterone. Progesterone has been shown to have positive effects on collagen synthesis and connective tissue integrity. Studies have suggested that progesterone can stimulate fibroblast activity and collagen production, promoting skin firmness and elasticity. This may contribute to the anti-aging effects of progesterone on skin health. Progesterone has also been shown to enhance the wound healing process by promoting tissue repair and collagen deposition at the site of injury. By modulating inflammation, fibroblast function, and growth factor signaling, progesterone can support the formation of new collagen fibers and the remodeling of tissue during wound healing. To increase progesterone we can use progesterone, pregnenolone or LH analogs like HCG and HMG. Another benefit of progesterone is that it can reduce water retention caused by estrogen dominance. However we don’t want to overdose progesterone since it’s a feminizing hormone in excess.

Pro-oxidant properties: Testosterone can act as an antioxidant by reducing oxidative stress and protecting cells from damage caused by reactive oxygen species (ROS). However testosterone has also been reported to exhibit pro-oxidant properties under certain conditions. Testosterone can undergo redox cycling, leading to the generation of ROS such as superoxide anion and hydrogen peroxide. These ROS can induce oxidative damage to cellular components, including lipids, proteins, and DNA. The pro-oxidant effects of testosterone are thought to be mediated through various mechanisms, including the activation of NADPH oxidase, mitochondrial dysfunction, and the formation of testosterone metabolites that can generate ROS. Vitamin C and E, NAC, Coenzyme Q10, curcumin, ashwagandha, resveratrol, Alpha-lipoic acid and glutathione are great antioxidant supplements that can help counteract the pro-oxidant effects of testosterone and improve overall cellular health.


Other than that HGH and certain steroids like oxandrolone and nandrolone is also good at increasing collagen synthesis.

Did you copy and paste this from somewhere but not cite the source material?
No I wrote it myself. I forgot some though, and it’s to late to edit the post now. But olive leaf extract and grape seed extract also have beneficial effects on basically all of these pathways (except progesterone, it doesn’t seem to effect it). And might be safer options compared to green tea extract and resveratrol since they both can have anti-thyroid properties. And the extract of green tea have also been shown to have hepatoxic properties. Other than that BPC 157 are famous for woundhealing and collagen support so it should also be mentioned.

just use HGH and deca as everyone should be doing, those are the only things that really put any muscle on you anyways, testosterone certainly isnt the primary muscle builder thats for damn sure

HGH is great, especially for collagen synthesis. Regarding deca im concerned with certain side effects like sexual dysfunction (aka deca dick) and negative impact on dopamine and mood. It’s also seem to be worse than testosterone regarding cholesterol and blood pressure.

I think the safest cycle, that will still provide good benefits long term, is low dose testosterone 200-300mg/week and 3-6iu/day HGH. Are you sure that HGH have better muscle building properties than testosterone though? I’ve read it’s the other way around, despite both being good ones.
 
Another factor might be high DHT. From what I’ve read DHT seem to be more inhibiting of collagen synthesis than testosterone. Indirect increase in DHT may actually be the main culprit behind the collagen inhibiting effects from high testosterone rather than testosterone itself. It would be interesting to investigate that theory further.

To lower DHT saw palmetto, stinging nettle root and pumpkin seeds are good options since they inhibit both type 1 and 2 of 5a-reductase. Drugs like finasteride inhibit mostly type 2, and it’s type 1 that is found in joints, tendons and skin. A downside with inhibiting type 1 however is that it can decrease allopregnanolone, to counteract this we can supplement with pregnenolone and vitamin B6. B6 is involved in the metabolism of steroid hormones and can support the activity of enzymes like 3α-HSD, which convert precursor molecules to allopregnanolone.
 
I use a lot of marine and bovine collagen in dips, soups, sauces, etc., as thickeners. Also gelatin. This is when I'm trying to make healthier versions of normie foods.

Maybe providing some of those precursors will assist down the line with actual collagen synthesis.
