Synthetic gastric peptide fragment

BPC-157 is a synthetic 15-residue peptide fragment derived from a sequence identified in gastric juice. Published research is dominated by rodent and in vitro models; no peer-reviewed controlled human trials have been published.

Preclinical (rodent and in vitro) literature

Copper-binding tripeptide complex

GHK-Cu is a copper-binding tripeptide complex studied across in vitro, rodent, and topical-cosmetic models, primarily in the context of extracellular matrix and skin biology research.

In vitro, animal, and topical-cosmetic literature

Synthetic GHRH analogue (with or without DAC)

CJC-1295 is a synthetic GHRH analogue investigated in early-phase human pharmacology studies and in GHRH-knockout rodent models. Published primary human research is limited to small Phase I/II pharmacokinetic and pharmacodynamic trials.

Phase I/II human pharmacology and rodent literature

Naturally occurring actin-binding peptide

Thymosin Beta-4 (Tβ4) is a 43-residue actin-binding peptide expressed in many human tissues. Published research spans in vitro cell-biology assays, rodent models, human-organoid work, and a small number of early-phase clinical studies (e.g., in ophthalmology and cardiovascular research).

Cell biology, rodent, and early-phase clinical literature

Synthetic pineal tetrapeptide

Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied in cellular ageing, gene-expression, and telomere-biology models. Most primary literature originates from a small number of research groups; controlled human clinical trials are absent from PubMed-indexed peer-reviewed sources.

In vitro, animal, and limited human cell-line literature

Synthetic ACTH(4–7)-derived heptapeptide analogue

Semax is a synthetic heptapeptide derived from ACTH(4–7), most extensively characterised in rodent models of cerebral ischaemia and in vitro neurobiology assays. Approved in the Russian Federation as a research and clinical compound; not approved for human therapeutic use in the United States, United Kingdom, or European Union.

Rodent neurobiology and in vitro literature

Synthetic tuftsin-derived heptapeptide

Selank is a synthetic heptapeptide analogue of the immunopeptide tuftsin, primarily characterised in rodent behavioural models (anxiety, stress, withdrawal) and in vitro neurochemistry assays. Regulatory status varies — research-use context only on this platform.

Endogenous KISS1-receptor agonist fragment

Kisspeptin-10 is a C-terminal fragment of the KISS1 gene product that activates the KISS1R (GPR54) receptor. Published research spans cell-based signalling assays, knockout-mouse models, and human reproductive-endocrinology pharmacology studies, alongside emerging bone-biology research.
