Educational guides on research peptides.
Clear, cited explainers on the peptides we list — what they are, how they work, what the published literature reports on dosing and safety, and how to store them. Written for informed researchers and curious readers. Not medical advice.
What Are Peptides? A Plain-English Introduction
Peptides are short chains of amino acids that sit between single amino acids and full proteins. Here's what that actually means, why researchers care, and where regulation draws the line.
Types of Peptides: A Map of the Six Main Classes
Healing peptides, growth-hormone secretagogues, metabolic, cognitive, mitochondrial, cosmetic — a functional classification of the peptides most commonly seen in research.
BPC-157: The Complete Research Guide
Body Protection Compound-157 is the most-studied "healing" peptide in animal literature. Here's what the evidence actually shows on gut repair, tendon healing, dosing ranges and risks.
TB-500 (Thymosin Beta-4): Mechanism, Dosing, Risks
Thymosin Beta-4 fragment used in tissue-repair research. Mechanism of action, soft-tissue and cardiac findings, and the human-context dosing ranges reported in the literature.
GHK-Cu: Copper Peptide Research Explained
The copper-binding tripeptide behind a huge cosmetic and wound-repair literature. Mechanism, evidence for skin and hair, safe reconstitution and storage.
Retatrutide: The Triple-Agonist Obesity Peptide
The GLP-1 / GIP / glucagon triple agonist making phase-2 headlines. How it differs from semaglutide and tirzepatide, trial data, reported side-effect profile.
CJC-1295 (No DAC): A Short-Half-Life GHRH Analog
The non-DAC variant of CJC-1295 — a GHRH analog with a pulsatile profile typically paired with Ipamorelin. Mechanism, dosing ranges and why the "no DAC" version matters.
Ipamorelin: The Selective Ghrelin Mimetic
A selective GHRP with minimal cortisol and prolactin spillover. Why it's usually paired with CJC-1295, the literature, and dosing ranges.
MOTS-C: The Mitochondrial-Derived Peptide
A 16-amino-acid peptide encoded inside mitochondrial DNA — implicated in insulin sensitivity, metabolic flexibility and exercise mimetics. The evidence to date.
Tesamorelin: FDA-Approved GHRH Analog
The only GHRH analog with FDA approval (for HIV-related lipodystrophy). Trial data, visceral fat findings, dosing and the off-label research interest.
