GHK-cu and oral collagen peptides

[Clavicular's Hammer]

Collagen supplementation's effectiveness has drawn conflicting findings over the years.

Still, my recommendation is this: when using GHK-cu, or even BPC157, for tendon repair or skin rejuvenation, supply the raw materials required for those repairs.

Some will say that sufficient total protein intake makes extra supplementation unnecessary. That view has holes, though—for instance, consuming large amounts of meat-derived methionine can cause the body to burn through a great deal of glycine. In other words, a meat-heavy diet may actually lower free glycine levels. Collagen is 33% glycine, and certain studies indicate vegans have higher glycine levels than people who eat a lot of meat.

So regardless of what anyone concludes from the research, if healthier skin, tendons or hair is the aim, spend an additional $30 and provide your body with the building blocks to achieve it

For more than a year, collagen peptide has been going into my protein shakes, and GHK-CU has been pinned for the past 3 months. I had planned to drop the collagen, since the benefits didn't seem to justify the expense, but now that GHK is in the mix, I believe the two work well together. If my diet included more protein, I think results would improve further, though getting enough protein has always been difficult for me.

If you have the strongest conviction in something, that itself will assist you in manifesting collagen production. Namaste

As far as injectable options go, though, the bro compounds (GH peptides along with high-normal testosterone levels) carry significantly stronger human evidence for collagen support than anything found in KLOW. I've attached some relevant information from Gemini, noting that GHK-Cu doesn't rank highly for joints because its evidence leans more toward skin.

Testosterone for female collagen synthesis and overall joint health:

71% of menopausal women get joint pain. New data shows testosterone protects cartilage, prevents muscle loss, and reduces arthralgia severity.

What's the source of this document? Is the GHK they're referring to injected or applied topically?

All it states is that clinical data is lacking, which makes it tough to determine whether it works or not. Plus, the focus is narrowed to tendons and ligaments.

That might be accurate. However, a lot of us aren't looking to use full HGH or testosterone. So without those, we're left making do with whatever alternatives fit our situation

My hands used to hurt at the joints, and I even had trigger finger. TRT took care of all of that. The real problem was low testosterone all along. These days I'm really happy with TRT, though I get why some folks are hesitant about starting it.
