Peptide guides

Every guide separates three things marketing collapses into one: what the published evidence shows, what regulators have actually said, and what the math looks like. Where human data doesn't exist, the first paragraph says so.

Foundations

How peptide reconstitution works

The concentration math, bacteriostatic water, storage, and the conversion errors the FDA has documented.

Molecule guide · skin & repair

GHK-Cu (Copper Peptide)

What GHK-Cu actually does: topical evidence, injectable unknowns, the legal line between the two, dosage math, and the blue authenticity test.

Molecule guide · inflammation

KPV Peptide

KPV exploded in gut-health circles. What the alpha-MSH fragment is, what preclinical research shows, the missing human data, and the dosage math.

Molecule guide · sexual health

PT-141 (Bremelanotide)

PT-141 has an FDA-approved twin: Vyleesi. What the approval covers, what the gray market sells, blood-pressure warnings, and the vial math.

Molecule guide · recovery

BPC-157

BPC-157 honestly reviewed: rodent data vs zero human trials, FDA Category 2 status, WADA prohibition, reported side effects, and dosage math.

Molecule guide · metabolism

MOTS-c

MOTS-c is a mitochondrial peptide on the FDA's 2026 review docket. The exercise-mimetic evidence, what the PCAC review decided, and the math.

Molecule guide · recovery

TB-500

TB-500 vs thymosin beta-4, the real state of the evidence, why it appears in doping sanctions, and the reconstitution math for typical vials.

Pillar · foundations

What Are Peptides?

Peptides explained plainly: the five things people mean by the word, which are approved drugs, whether they are safe or legal, and what works.

Foundations · reconstitution

Bacteriostatic Water

Bacteriostatic water for peptides: how it differs from sterile water, the 28-day rule after opening, storage, and how volume changes your math.

Pillar · weight loss

Peptides for Weight Loss

Weight-loss peptides ranked by evidence: approved GLP-1s that work, the next generation in trials, and the gray-market tier sold on hope.

Pillar · performance

Peptides for Muscle Growth

GH secretagogues raise hormones, not proven muscle. The honest evidence ranking, IGF-1 LR3 risks, WADA status, and what actually has data.

Molecule guide · GH axis

Ipamorelin

Ipamorelin raises growth hormone measurably; outcomes were never proven. The abandoned pharma history, FDA Category 2 status, and dosage math.

Molecule guide · GH axis

Sermorelin

Sermorelin is the only GH peptide with a real FDA approval in its past. What that legitimizes, the adult evidence gap, and nightly dosing math.

Molecule guide · GH axis

Tesamorelin

Tesamorelin is FDA-approved with real visceral-fat data, for HIV lipodystrophy. What the trials showed, off-label reality, cost, and dosing.

Guide · longevity

NAD+ Injections

NAD+ drips and shots examined: what declines with age, whether injected NAD+ reaches cells, how oral precursors compare, and what clinics charge.

Reference · GLP-1

GLP-1 Name Decoder

One molecule, two brands: the decoder table for every GLP-1 drug and brand name, answering all the 'are X and Y the same' questions at once.
