To store research peptides correctly in the laboratory, keep lyophilized (powder) material cold and dry — sealed with desiccant and held long-term at −20 °C or colder (−80 °C for extended storage), protected from light and moisture. Once a peptide is reconstituted into solution, refrigerate it at 2–8 °C, keep aliquots to avoid repeated freeze–thaw, […]
Research peptides are short chains of amino acids (typically ~2–50 residues) supplied as laboratory reference materials for in-vitro and preclinical study. The phrase “research use only” (RUO) means these materials are not drugs, dietary supplements, or products intended for human or veterinary use — they exist solely to support controlled laboratory investigation. Everything below is […]
Kisspeptin is a neuropeptide encoded by the KISS1 gene that acts on the KISS1R (GPR54) receptor and is a key upstream regulator of gonadotropin-releasing hormone (GnRH) release within the reproductive (hypothalamic–pituitary–gonadal, or HPG) axis. Kisspeptin-10 is a commonly studied active 10–amino-acid C-terminal fragment of the parent peptide. This article is educational only. Kisspeptin and kisspeptin-10 […]
The CJC-1295 / Ipamorelin combo is a single research preparation that pairs CJC-1295 — a growth-hormone-releasing hormone (GHRH) analog that acts on the GHRH receptor (GHRH-R) — with Ipamorelin, a selective ghrelin/growth-hormone-secretagogue (GHS-R) receptor agonist. The two are blended together because, in preclinical and laboratory research, they engage two distinct and complementary nodes of the […]
L-carnitine is a naturally occurring amino-acid derivative (synthesized in the body from lysine and methionine) that plays a central role in transporting long-chain fatty acids across the inner mitochondrial membrane for β-oxidation, the process by which fatty acids are broken down for energy. It is one of the most widely studied compounds in cellular metabolism […]
HCG (human chorionic gonadotropin) is a glycoprotein hormone composed of an α subunit and a β subunit. It is produced by placental trophoblast cells during pregnancy and is widely studied in reproductive endocrinology research, where it acts on the luteinizing hormone/chorionic gonadotropin receptor (LHCGR). This article is strictly educational and describes physiology and laboratory research […]
Semax and Selank are both synthetic peptides developed in Russia and widely studied in central nervous system (CNS) and neuropeptide research, but they derive from different parent molecules. In published preclinical literature, Semax is a fragment-derived analog of the adrenocorticotropic hormone sequence ACTH(4–10), while Selank is a synthetic analog of the immunomodulatory peptide tuftsin. Because […]
The defining difference between these three incretin research peptides is how many hormone receptors each one targets. Semaglutide is a single agonist that activates only the GLP-1 receptor. Tirzepatide is a dual agonist that activates both the GIP and GLP-1 receptors. Retatrutide is a triple agonist that activates the GIP, GLP-1, and glucagon receptors. That […]
Melanotan 1 and Melanotan 2 are both synthetic analogs of the natural hormone α-melanocyte–stimulating hormone (α-MSH) studied in melanocortin and pigmentation research, but they differ most importantly in receptor selectivity. Melanotan I (afamelanotide) is a more selective, α-MSH–oriented analog whose activity is directed largely at the melanocortin-1 receptor (MC1R). Melanotan II is a broader, non-selective […]
Melanotan I (melanotan-1) is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH), a peptide studied in the laboratory for its activity at melanocortin receptors involved in pigmentation. The closely related synthetic α-MSH analog afamelanotide is an approved medicine for a rare light-sensitivity disorder called erythropoietic protoporphyria (EPP). The Melanotan I sold here is supplied strictly as […]
