Peptide Directory

Peptides, and what the record actually shows

A seller with a GLP-1 on the shelf usually has a peptide next to it. The grouping below runs on the weight of published evidence rather than on the body part being marketed, since the seller page rarely puts those two things side by side. Each guide cites primary research, and a thin record is stated on the card before you click.

Most of the peptides listed here hold no FDA approval and reach patients through compounding pharmacies. Read this as background rather than medical advice, and take any decision to a licensed clinician.

A low grade is a finding

A weak grade does not mean the compound does nothing. It means nobody has run the study that would settle it, and that absence is itself the result. Sellers price the promising ones the same as the proven ones.

Compounded is not approved

An FDA approval attaches to a named product from a named manufacturer. A compounded peptide is prepared by a pharmacy against a prescription and carries no such approval. That is how the supply chain works, not an accusation about any one seller.

The headline is rarely the rate

Peptide pricing behaves like GLP-1 pricing. The advertised figure is often a first month, a membership fee, or a multi-month prepay divided out. The seller review is where the standing rate is written down.

Grade A — approved, or strong randomized evidence

An FDA-approved product for this use, or randomized trials large enough to rely on.

PT-141

Grade A

Desire & arousal

A melanocortin agonist working on arousal pathways in the brain. It holds a genuine approval, as Vyleesi, and is sold well past the population that approval covers.

Gonadorelin

Grade A

Testosterone & fertility axis

A gonadotropin-releasing hormone, used mostly alongside TRT to keep the body's own testosterone and fertility axis running.

Listed by 7 sellers on the register →

Tesamorelin

Grade A

Visceral fat, approved use

The one GHRH analog here carrying an approved indication: Egrifta, for visceral abdominal fat in HIV-associated lipodystrophy. Body-composition use is off-label.

Grade B — real trials, real limits

Human trials exist and point one way, but they are small, short, or run in a narrower population than the people being sold it.

NAD+

Grade B

Energy & cellular aging

The coenzyme behind cellular energy production and DNA repair. Clinics deliver it by drip or injection; supplement makers sell the precursors instead.

Sermorelin

Grade B

Own growth-hormone output

A GHRH analog. Rather than supplying growth hormone, it signals the pituitary to release what the body already makes. Taken for sleep, recovery and body composition.

Listed by 107 sellers on the register →

Grade C — mechanism and anecdote, not outcomes

A plausible mechanism, animal work, or small uncontrolled series. Nothing here establishes that it does what the seller says in humans.

Glutathione

Grade C

Antioxidant infusions

An antioxidant the body already produces, sold back to it by infusion, injection or capsule for oxidative stress, skin and general wellness.

GHK-Cu

Grade C

Skin & hair repair

A copper-binding tripeptide. Cosmetic topical use is mainstream; the injected version is a different proposition entirely.

Listed by 31 sellers on the register →

BPC-157

Grade C

Tendon & gut repair

A synthetic peptide fragment with a large following in recovery circles and a thin human evidence base. The healing work behind it is mostly animal work.

Listed by 14 sellers on the register →

TB-500

Grade C

Soft-tissue recovery

A synthetic fragment of thymosin beta-4, taken for muscle, tendon and soft-tissue recovery and very often stacked with BPC-157.

CJC-1295 / Ipamorelin

Grade C

Own growth-hormone output

Two peptides sold as a single protocol: a GHRH analog alongside a selective secretagogue, both aimed at the body's own growth-hormone output.

Listed by 10 sellers on the register →

Ipamorelin

Grade C

Own growth-hormone output

A selective growth-hormone secretagogue, valued in practice for troubling people less than the alternatives. Taken for sleep, recovery and body composition.

Listed by 6 sellers on the register →

Grade D — sold well ahead of its evidence

Marketed widely with little or no human outcome data behind the claim.

MOTS-c

Grade D

Mitochondrial claims, mouse data

A mitochondrial-derived peptide sold on what it did to mice, where it behaved as a metabolic regulator. No human trial has found that it causes weight loss, and it holds no FDA approval.
