Reference pages for the peptides covered on Peptide Resource Hub: what each one is, the mechanism behind it, researched benefits, reported side effects, and typical dosing protocols with an evidence rating.

BPC157

Emerging evidence

Body Protection Compound-157 is a gastric peptide fragment with research support for tissue repair, gut integrity, and anti-inflammatory effects. Not medical advice; consult a provider.

Semaglutide is a GLP-1 receptor agonist that slows gastric emptying and increases satiety signaling. FDA-approved for type 2 diabetes (Ozempic) and chronic weight management (Wegovy). Weekly dosing with dose escalation typically over 4–8 weeks. Not medical advice; consult a provider.

Tirzepatide is a first-in-class dual GLP-1/GIP receptor agonist. FDA-approved for type 2 diabetes (Mounjaro) and chronic weight management (Zepbound). SURMOUNT trials showed 20–25% body weight reduction — among the highest of any approved agent. Weekly dosing with 5-week dose escalation. Not medical advice; consult a provider.

Cagrilintide

Preclinical only

Cagrilintide is a long-acting amylin analog — a different mechanism than GLP-1 agonists. It works via amylin receptors in the brain to reduce appetite and slow gastric emptying. In Phase 3 trials; not yet FDA-approved as standalone. Being studied in combination with semaglutide (CagriSema) for enhanced efficacy. Not medical advice; consult a provider.

Experimental combination targeting multiple metabolic pathways: triple agonist (Retatrutide: GLP-1/GIP/glucagon) plus amylin pathway (Cagrilintide) for broad coverage. No FDA-approved combination product; research-phase protocol only. Requires experienced provider oversight for dosing and monitoring. Not medical advice; consult a provider.

GHK-CU

Emerging evidence

Copper peptide complex (glycyl-L-histidyl-L-lysine-copper) with research in skin repair, wound healing, and antioxidant effects. Not medical advice; consult a provider.

Ipamorelin

Clinical evidence

Growth hormone–releasing peptide (GHRP) that stimulates GH release with relatively selective action. Not medical advice; consult a provider.

Epithalon

Preclinical only

Tetrapeptide (Ala-Glu-Asp-Gly) studied for potential telomere and longevity effects. Not medical advice; consult a provider.

DSIP

Emerging evidence

Delta sleep-inducing peptide, researched for sleep modulation and stress response. Not medical advice; consult a provider.

NAD+

Clinical evidence

Nicotinamide adenine dinucleotide is a coenzyme involved in energy metabolism and cellular repair. Not medical advice; consult a provider.

Thymosin Alpha-1

Emerging evidence

Immunomodulatory peptide derived from thymus; research in immune function and infection. Not medical advice; consult a provider.

Read the Thymosin Alpha-1 page →

Retatrutide is a GLP-1/GIP/glucagon triple agonist with strong human clinical data for weight loss and metabolic improvement. It represents a latest-generation breakthrough in incretin therapy. Not medical advice; consult a provider.

Tesamorelin / Tesmorelin

Emerging evidence

Tesamorelin is a growth hormone–releasing hormone (GHRH) analog. It is FDA-approved for HIV-associated lipodystrophy, giving providers clinical familiarity. Not medical advice; consult a provider.

Read the Tesamorelin / Tesmorelin page →

Sermorelin Acetate

Emerging evidence

Sermorelin is a short GHRH fragment (1-29) that stimulates pituitary GH release. It has a short half-life, supporting pulsatile dosing. Not medical advice; consult a provider.

CJC-1295 Without DAC

Emerging evidence

CJC-1295 (no DAC) is a GHRH analog with a short half-life, allowing pulsatile dosing. Paired with Ipamorelin it can extend the GH release window without sustained elevation. Not medical advice; consult a provider.

Read the CJC-1295 Without DAC page →

CJC-1295 With DAC

Emerging evidence

CJC-1295 with DAC (drug-affinity complex) binds to albumin and extends half-life, producing sustained GH elevation. Suited for less frequent dosing. Not medical advice; consult a provider.

Thymalin

Preclinical only

Thymalin is a thymic peptide complex studied for immune modulation and aging. Evidence is largely preclinical. Not medical advice; consult a provider.
