Stacks

Named pairings. One job per peptide — do not run two GLP-1s together.

Peptides

HealingResearch only

BPC-157

People look this up for sore tendons, gut lining, and general repair. It is research-only.

500 mcg · Once or twice daily

HealingResearch only

TB-500

Usually paired with BPC-157 when someone wants a more whole-body repair protocol.

2.5 mg · Twice weekly (loading), then weekly

HealingResearch only

GHK-Cu

A copper peptide. Creams use it for skin; the vial is a research injectable.

1.5 mg · Once daily

HealingResearch only

KPV

Anti-inflammatory tripeptide used in gut and skin protocols.

500 mcg · Once or twice daily

Growth hormoneResearch only

CJC-1295 (no DAC)

A growth-hormone releasing analog, often stacked with ipamorelin at night.

200 mcg · Once nightly, or 1–2× daily

Growth hormoneResearch only

Ipamorelin

A short GH pulse. People use it for sleep and recovery, not as a steroid substitute.

200 mcg · 1–3 pulses daily

Growth hormoneApproved molecule

Tesamorelin

An approved analog studied for visceral fat. Still a prescription decision.

2 mg · Once daily

Growth hormoneResearch only

Sermorelin

Classic GHRH fragment; gentler GH pulse for sleep and recovery.

300 mcg · Nightly

Growth hormoneResearch only

Hexarelin

Potent GHRP; effective but desensitizes faster.

150 mcg · 1–2× daily

Growth hormoneResearch only

MK-677

Oral ghrelin mimetic; daily GH/IGF-1 lift without injections.

15 mg · Once daily, oral

Growth hormoneHigh risk

IGF-1 LR3

Long-acting IGF-1 analog. High-risk research compound.

40 mcg · Once daily, short cycle

MetabolicApproved molecule

Semaglutide

A weekly GLP-1. Brand names exist as medicines. This catalog is educational, not a prescription.

1 mg · Once weekly

MetabolicApproved molecule

Tirzepatide

A weekly dual-agonist many people compare with semaglutide for appetite.

7.5 mg · Once weekly

MetabolicHigh risk

Retatrutide

An investigational triple-agonist. Not an everyday starter.

4 mg · Once weekly (trial-style)

MetabolicResearch only

hGH fragment aimed at lipolysis without IGF-1 rise.

300 mcg · Once daily, often fasted

MetabolicResearch only

MOTS-c

Mitochondrial peptide studied for insulin sensitivity and exercise mimicry.

10 mg · 2–3× weekly

MetabolicInvestigational

Cagrilintide

Long-acting amylin analog; often paired with GLP-1s in trials.

1.2 mg · Once weekly

MetabolicResearch only

5-Amino-1MQ

Oral NNMT inhibitor used in body-composition experiments.

100 mg · Once or twice daily, oral

CognitiveResearch only

Semax

A nasal peptide some countries use for focus. Not FDA-approved.

400 mcg · 1–2× daily, nasal

CognitiveResearch only

Selank

A related nasal peptide people look up for calm.

LongevityInvestigational

SS-31

Mitochondrial-targeted tetrapeptide (elamipretide).

10 mg · Once daily

LongevityResearch only

NAD+

Not a peptide — a coenzyme. Clinics give it IV; Mix is for a subcutaneous vial. It can sting, and a fast IV push is a bad idea.

50 mg · 2–5× weekly subq, or a short daily block
