Wetenschap

KineticPep supplies lyophilized peptides used by research groups working on tissue repair, metabolic regulation, growth-hormone signalling, neuroprotection, and longevity biology. This page collects background on the peptide families in our catalogue, with links to the underlying scientific literature, for researchers who want to verify a molecule before ordering.

Peptide families in the KineticPep catalogue

GLP-1 / GIP / glucagon agonists

This family includes Semaglutide, Tirzepatide, and Retatrutide. GLP-1 (glucagon-like peptide 1) is an incretin hormone released by intestinal L cells; the synthetic analogs act as agonists on the GLP-1 receptor with dose-dependent effects on insulin secretion and gastric emptying in vitro. Tirzepatide adds GIP receptor agonism; Retatrutide adds glucagon receptor agonism as a triple agonist. All three are under active investigation for metabolic research applications.

Tissue repair peptides

BPC-157 is a synthetic pentadecapeptide derived from a fragment of human gastric juice protein BPC (Body Protection Compound). TB-500 is a synthetic form of Thymosin Beta-4 fragment. Both are studied in preclinical models of soft-tissue and vascular repair. Reconstitution requires an acidic carrier for BPC-157 (0.6% acetic acid water) rather than plain bacteriostatic water.

Growth-hormone secretagogues

Sermorelin, GHRP-2, GHRP-6, Ipamorelin, CJC-1295 (with and without DAC), Tesamorelin, and MK-677. This family targets the GHRH receptor or the ghrelin receptor (GHS-R) with the goal of stimulating pituitary GH release in research systems. Half-lives differ substantially between molecules and drive experimental design choices.

Longevity and mitochondrial-signalling peptides

Epitalon (Ala-Glu-Asp-Gly) is a tetrapeptide studied for its effects on telomerase activity and circadian regulation in cell-culture models. MOTS-c is a mitochondrial-derived peptide encoded within the 12S rRNA region of the mitochondrial genome and studied for metabolic and exercise-physiology endpoints.

Copper-complex tripeptides

GHK-Cu (Gly-His-Lys copper complex) is a naturally occurring plasma peptide studied for its role in copper delivery to fibroblasts and modulation of tissue remodelling in dermal research models. GHK-Cu requires an acidic carrier (0.6% acetic acid) rather than bacteriostatic water.

Cognitive research peptides

Selank and Semax are heptapeptides originally developed at the Institute of Molecular Genetics (Moscow) and studied for GABAergic and enkephalin modulation in preclinical anxiety and neuroprotection paradigms.

Where to find primary literature

PubMed (pubmed.ncbi.nlm.nih.gov) is the reference index for peer-reviewed literature on any peptide in our catalogue. A useful starting query is the peptide name combined with terms such as “pharmacokinetics”, “receptor binding”, or the specific research endpoint (for example “BPC-157 tendon” or “MOTS-c mitochondrial”).

Solvents and reconstitution

Most peptides in the catalogue reconstitute cleanly in Bacteriostatic Water (0.9% benzyl alcohol) at room temperature. Acid-sensitive peptides such as BPC-157, TB-500, and copper-complex peptides (GHK-Cu) reconstitute in Acetic Acid Water 0.6% instead. Both solvents are stocked as separate SKUs to avoid substitution errors. Detailed guidance is available in the FAQ.
