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.
The Anti-Aging Stack for Your 40s: What Longevity Researchers Are Actually Running
GHK-Cu, BPC-157 and Ipamorelin form one of the most-discussed longevity protocols. Mechanisms, evidence and the rationale, written for the cohort that actually runs it.
The Beginner Peptide Stack Everyone Recommends Is Wrong
A contrarian take on multi-peptide beginner protocols. Why fewer compounds, longer durations and proper baseline measurement give first-time researchers actual data instead of noise.
The Quiet Rise of Semax: From Soviet Nasal Spray to Silicon Valley Nootropic
A peptide developed in 1980s Moscow for stroke patients, approved as a Russian pharmaceutical in 1994, and quietly stacked four decades later by founders. The story plus the science.
The Peptide Nobody Talks About But Every Longevity Researcher Is Quietly Stacking
MOTS-C is encoded inside the mitochondrial genome, activates AMPK, and produces signalling that overlaps with exercise. Cell Metabolism and Nature Communications papers; almost no online noise.
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.
Semax: ACTH Analogue for Cognitive & Neuroprotective Research
Synthetic heptapeptide derived from ACTH(4-10) - upregulates BDNF 3–5×, activates dopaminergic and serotonergic systems, and has human clinical data in stroke recovery. Mechanism, dosing, storage.
Retatrutide vs. Tirzepatide vs. Semaglutide: The Honest Breakdown
Everyone's calling Retatrutide the "King of GLP-1s" - but that framing misses what actually matters. A side-by-side breakdown of receptor targets, trial efficacy, side-effect profiles, and which compound fits which research context.
Why Your BPC-157 Isn't Working (It's Probably Not a Dosing Problem)
Six mistakes that silently degrade BPC-157 before it ever reaches target tissue - bad reconstitution, wrong storage, degraded bac water, injection site errors, and sourcing quality. The fix for each one.
Peptide Tier List 2026: Ranking All 11 Peptides by Risk-to-Reward
Most peptide content refuses to have opinions. Here's an S-to-C tier ranking of every peptide we stock - judged by evidence strength, side-effect burden, and beginner accessibility. Opinionated and defensible.
Why Women Are Quietly Driving the Peptide Market - And Which 4 Deliver
The forums skew male. The buyer data doesn't. Here are the 4 peptides with the strongest published research rationale for female-specific endpoints - collagen, gut health, body composition, and recovery.
GHK-Cu vs. Retinol vs. Skincare Peptides: What Actually Moves the Needle?
Every skincare brand claims peptides now. Most aren't GHK-Cu. Here's what the published research actually shows - and why research-grade copper peptide is a fundamentally different category from OTC serums.
