One evidence model for every peptide.

Synthetic peptide

A synthetic 15-amino-acid research peptide with extensive preclinical claims but little interpretable human efficacy evidence.

Peptide analog

An investigational triple GIP, GLP-1, and glucagon receptor agonist in late-stage metabolic research.

Peptide analog

A growth hormone-releasing hormone analog with an FDA-approved use for a specific HIV-associated lipodystrophy population.

Mitochondrial-derived peptide

A mitochondrial-derived signaling peptide studied mainly in cells, animals, and small human physiology experiments.

Peptide fragment

A marketed name for a synthetic thymosin-beta-4-related fragment; product identity and evidence are often conflated with full-length thymosin beta-4.

Synthetic peptide

A synthetic ghrelin-receptor agonist studied as a growth hormone secretagogue, without an FDA-approved therapeutic product.

Peptide analog

A GLP-1 receptor agonist used in FDA-approved medicines with a large randomized human evidence base.

Peptide analog

A dual GIP and GLP-1 receptor agonist used in FDA-approved medicines for defined metabolic indications.

Peptide analog

A synthetic fragment of growth hormone-releasing hormone with historical clinical use and no current FDA-approved drug product.

Synthetic peptide

A mitochondria-targeted peptide known as elamipretide; FDA accelerated approval is limited to a specific Barth syndrome indication.

Peptide analog

A long-acting growth hormone-releasing hormone analog studied in early human pharmacology research.

Peptide fragment

A tripeptide fragment derived from alpha-melanocyte-stimulating hormone and studied primarily in preclinical inflammation models.

Native peptide

A naturally occurring copper-binding tripeptide studied in tissue remodeling, skin, and wound biology.

Synthetic peptide

A synthetic version of a thymic peptide investigated as an immune modulator and used clinically in some countries outside the United States.

Native peptide

A naturally occurring actin-binding peptide studied in tissue repair and regenerative biology.

Native peptide

A human antimicrobial peptide involved in innate immune signaling and host defense.

Peptide fragment

A synthetic fragment of human growth hormone investigated for metabolic effects, with limited human evidence.

Synthetic peptide

A synthetic tetrapeptide associated with aging research, supported mainly by limited and difficult-to-verify clinical literature.

Peptide analog

A synthetic ACTH-derived peptide investigated for neurologic and cognitive effects, with limited generalizable human evidence.

Peptide analog

A synthetic tuftsin analog studied for neurobehavioral effects, with a small and geographically concentrated evidence base.

Native peptide

A small endogenous research peptide associated with sleep physiology, with uncertain therapeutic relevance.

Melanocortin receptor agonist

A melanocortin receptor agonist; bremelanotide is FDA approved for one narrowly defined indication under the Vyleesi label.

Melanocortin receptor agonist

An unapproved synthetic melanocortin analog promoted for tanning and sexual effects despite important safety uncertainty.

Native peptide

An endogenous tripeptide involved in cellular redox chemistry; treatment claims require route- and formulation-specific evidence review.
