Explainers

What are the real kpv peptide benefits? See what early and animal research explores for inflammation, gut, skin, and immunity, plus its honest research status.

What is dihexa? Learn about this angiotensin IV-derived research compound studied in animals for cognition, why it is not FDA-approved, and why caution matters.

What is the GHK Cu peptide? Learn how this copper tripeptide works, why topical use is legal and common, and why injectable GHK-Cu is research-use only.

The kpv peptide is a short alpha-MSH fragment studied for anti-inflammatory, gut, and skin effects. Learn its research status, mechanisms, and safety facts.

MOTS-c is a mitochondrial-derived peptide studied for metabolism, energy, and longevity. Learn what research shows, its FDA status, and safety facts.

The 'NAD peptide' is a misnomer: NAD+ is a coenzyme (dinucleotide), not a peptide. Learn what it does, how it is sold, and why longevity claims are preliminary.

The PT 141 peptide (bremelanotide) is FDA-approved as Vyleesi for HSDD, but research-chemical PT-141 is not. Learn the key differences and safety facts.

What is tesamorelin? Learn how this GHRH analog works, its FDA-approved use for HIV lipodystrophy, its off-label reputation, and what the evidence shows.

What is BPC 157? A research-use-only peptide, not FDA-approved, studied mostly in animals for tissue repair. What the evidence shows and what it doesn't.

What is TB-500? A research-use-only peptide related to thymosin beta-4, not FDA-approved. What the preclinical evidence shows, and the safety unknowns.

A clear definition of peptides — what makes a peptide a peptide, how they differ from proteins and small molecules, why they're injected, and the major classes used in research and medicine.
