- GHK-Cu explained: the copper peptide your body makes less of with ageGHK-Cu is a tiny three-amino-acid peptide bound to copper. The body makes it naturally: blood levels run about 200 ng/mL at age 20 and fall to about 80 by age 60. In lab studies it boosted collagen at vanishingly small amounts and shifted the activity of more than 4,000 human genes. Here's what the research found — and what it didn't.Updated 19 SEPT 2026
- TB-500 explained: what the thymosin beta-4 research really showsTB-500 is the name used for lab-made thymosin beta-4, a repair protein found in nearly every tissue of the body. In animal studies, thymosin beta-4 helped skin wounds close faster, injured hearts recover and hair grow faster. Here's what the research found, where it thins out, and why the lab report on a TB-500 vial matters more than usual.Updated 19 SEPT 2026
- Ipamorelin explained: the growth hormone peptide that leaves stress hormones aloneIpamorelin is a five-amino-acid peptide that prompts the pituitary gland to release growth hormone. What made scientists sit up in 1998: it did it without raising the stress hormones cortisol and ACTH, even at more than 200 times the amount needed. Here's what the research found, what it didn't, and how to check a vial.Updated 19 SEPT 2026
- Tesamorelin explained: the peptide with real human trials behind itTesamorelin is a lab-made copy of GHRH, the signal that tells the pituitary gland to release growth hormone. Unlike most research peptides, it has big human trials behind it: in 412 people with HIV-related belly fat, deep abdominal fat fell 15% in six months while the placebo group's rose 5%. Here's what the research shows and where it stops.Updated 19 SEPT 2026
- BPC-157 explained: what the research really showsBPC-157 is a 15-amino-acid peptide copied from a protein in human stomach juice. In rat studies, it helped cut tendons, torn ligaments, gut injuries and skin wounds heal faster — which is why it gets so much attention. Here's what the research found, what it hasn't shown yet, and how to know what's in your vial.Updated 19 SEPT 2026
