BPC-157, for instance, has been shown in animal studies to accelerate gastrointestinal healing by 40% (Journal of Physiology, 2020). Their therapeutic scope includes wound healing and gut health.
• Growth Hormone Releasing Peptides (GHRPs) (e.g., GHRP-2, GHRP-6): These stimulate the pituitary gland to release growth hormone. A 2022 clinical trial in the Journal of Clinical Endocrinology & Metabolism found that GHRP-2 increased GH levels by 300% in healthy adults. They are used for muscle growth, fat loss, and anti-aging.
• Collagen Peptides (e.g., Type I, Type III): These are structural peptides that support skin, joint, and bone health. A 2023 meta-analysis in the Journal of Cosmetic Dermatology reported that collagen peptide supplementation improved skin hydration by 28% and joint pain by 15%.
• Antimicrobial Peptides (AMPs) (e.g., LL-37): These are part of the innate immune system, with broad-spectrum activity against bacteria and viruses. Research in Nature Reviews Drug Discovery (2021) highlights their potential in treating antibiotic-resistant infections.

Each type has a distinct mechanism and therapeutic scope, reinforcing that "what is peptide therapy" depends on the specific peptide and its intended application.

Peptide Technology: Pros and Cons

Peptide therapy offers significant advantages but also carries inherent limitations. Understanding these is critical for anyone exploring "what is peptide therapy."
