14 profiles

BPC-157

Body Protection Compound-157

Cat 1 — 2026
injectableoral
Evidence

15-amino acid peptide derived from human gastric juice. Promotes tissue repair, gut healing, and angiogenesis. Among the most-researched repair peptides available.

TB-500

Thymosin Beta-4 fragment

Cat 1 — 2026
injectable
Evidence

Synthetic fragment of Thymosin Beta-4. Promotes systemic tissue repair through actin regulation and stem cell activation. Often stacked with BPC-157.

Ipamorelin

Growth Hormone Secretagogue (selective)

Cat 1 — 2026
injectable
Evidence

The most selective GH secretagogue available. Stimulates strong growth hormone release with minimal cortisol or prolactin side effects. Considered the gold standard secretagogue.

GHK-Cu

Copper peptide / Glycyl-L-histidyl-L-lysine-Cu²⁺

Cat 1 — 2026
injectabletopical
Evidence

Naturally occurring copper-binding peptide found in human plasma. Declines significantly with age. Influences over 4,000 genes. Strongest evidence base for topical skin applications.

CJC-1295 / Ipamorelin Stack

CJC-Ipa / GH Stack / Secretagogue Combination

Cat 1 — 2026
injectable
Evidence

The most commonly prescribed GH secretagogue combination in US longevity medicine. CJC-1295 provides GHRH stimulation while Ipamorelin provides ghrelin receptor stimulation — two complementary pathways for natural GH optimization.

GLOW Blend

AminoClub GLOW / Cellular Peptide Blend

Cat 1 — 2026
injectable
Evidence

A proprietary AminoClub peptide blend formulated for skin rejuvenation, cellular repair, and anti-aging. Combines synergistic peptides targeting collagen synthesis, skin barrier function, and cellular regeneration.

KLOW Blend

AminoClub KLOW / Cellular Peptide Blend

Cat 1 — 2026
injectable
Evidence

A proprietary AminoClub peptide blend formulated for metabolic optimization, body composition, and longevity. Targets the GH axis, metabolic pathways, and cellular health simultaneously.

Wolverine Stack

BPC-157 / TB-500 Combination / Recovery Stack

Cat 1 — 2026
injectable
Evidence

The most researched tissue repair combination in peptide science. BPC-157 and TB-500 work through complementary mechanisms — local repair signaling and systemic actin regulation — making them the gold standard recovery stack.

Ipamorelin

Growth Hormone Secretagogue (selective) / GHS

Cat 1 — 2026
injectable
Evidence

The most selective growth hormone secretagogue available. Stimulates strong GH release with minimal cortisol or prolactin side effects. Gold standard for GH axis optimization.

GHRP-6

Growth Hormone Releasing Peptide-6

RUO only
injectable
Evidence

Early GH secretagogue notable for strong appetite stimulation via ghrelin pathway. Studied for cachexia and muscle wasting. Also has gastroprotective properties similar to BPC-157.

IGF-1 LR3

Insulin-like Growth Factor-1 Long R3

RUO only
injectable
Evidence

Modified IGF-1 with 3x longer half-life. Directly stimulates muscle protein synthesis and satellite cell activation independent of the GH axis. Significant cancer risk concern.

Follistatin-344

FST-344 / Myostatin Inhibitor

RUO only
injectable
Evidence

Myostatin inhibitor studied for exceptional muscle growth by blocking the body's natural muscle-growth limiter. Dramatic animal model results. Significant organ growth safety concerns.

KPV

Lys-Pro-Val tripeptide / α-MSH fragment

Cat 1 — 2026
injectableoral
Evidence

Tripeptide fragment of alpha-MSH with potent gut anti-inflammatory effects. One of the few peptides with genuine oral bioavailability making it uniquely valuable for gut-specific research.

SS-31

Elamipretide / MTP-131 / Bendavia

RUO only
injectable
Evidence

Mitochondria-targeted tetrapeptide that protects the inner mitochondrial membrane. Reduces oxidative stress and restores ATP production. In Phase II and III clinical trials for heart failure and Barth syndrome.
