Most Researched Peptides
Most-studied compounds in the research community
Body Protection Compound-157
A 15-amino acid peptide fragment derived from a protective protein found in gastric juice. Remarkably effective at accelerating healing of tendons, ligaments, muscles, and gut tissue.
Epitalon
A synthetic tetrapeptide that activates telomerase, the enzyme responsible for lengthening telomeres. One of the only compounds with robust evidence for telomere extension in humans.
Ipamorelin acetate
A selective growth hormone secretagogue and ghrelin mimetic that stimulates GH release without significantly elevating cortisol or prolactin. One of the cleanest and most widely used peptides for body recomposition.
Ibutamoren
A non-peptide, orally active growth hormone secretagogue that mimics ghrelin, significantly elevating GH and IGF-1 levels. Unique in being orally bioavailable.
Ozempic
An FDA-approved GLP-1 receptor agonist that produces significant weight loss (average 14.9% body weight in clinical trials). One of the most clinically validated weight loss peptides available.
Thymosin Beta-4
A synthetic version of Thymosin Beta-4, a naturally occurring protein present in nearly all human cells. Promotes cellular healing, anti-inflammation, and tissue regeneration throughout the entire body.
Popular Peptide Stacks
Curated combinations for specific goals
Classic GH Stack
Muscle growth, fat loss, body recomposition
The most popular peptide stack for muscle growth and body recomposition. CJC-1295 provides sustained GHRH stimulation while Ipamorelin adds selective GH pulses without cortisol elevation.
Ultimate Healing Stack
Injury recovery, tissue repair, anti-inflammation
BPC-157 and TB-500 are highly complementary — BPC-157 works locally for tissue repair while TB-500 works systemically. Together they cover both acute and chronic injury healing.
Anti-Aging Protocol
Anti-aging, longevity, immune optimization
A comprehensive anti-aging stack combining telomere support (Epithalon), skin/tissue regeneration (GHK-Cu), and immune optimization (Thymosin Alpha-1).

FDA Approved & Prescription Peptides
These peptides have passed rigorous clinical trials and regulatory review
FPF-1070
A complex mixture of low-molecular-weight neuropeptides derived from porcine brain proteins. The only peptide-based nootropic with robust clinical evidence for Alzheimer disease and brain injury.
GnRH
A synthetic form of endogenous GnRH that stimulates the pituitary to release LH and FSH. Widely used in TRT protocols to maintain testicular size and function.
Human Menopausal Gonadotropin
A urinary-derived combination of LH and FSH used clinically for fertility treatment and in TRT protocols for testicular stimulation and spermatogenesis support.
Victoza
An FDA-approved once-daily GLP-1 receptor agonist for type 2 diabetes and weight management. Produces 5-8% average weight loss with established cardiovascular safety data.
