Peptide Sciences Shut Down: What Actually Happened, and What It Means for the Peptide Industry
On March 6, 2026, Peptide Sciences, one of the most recognized names in the research peptide space, quietly went dark. Visitors to the site were met with a farewell notice in place of the usual catalog: “After careful consideration, Peptide Sciences has made the...
AEDL Potential Actions on Inflammation in Lung Cells
AEDL, also referred to as Bronchogen, is a short peptide made of four amino acids that falls into the category of peptide bioregulators. This tetrapeptide is classified amongst the so-called Khavinson’s peptides, which stem from the team of researchers who have most... Tripeptide-1 and Its Potential Interactions with Dermal Cells
Tripeptide-1 is a tripeptide that is also referred to as GHK Basic, stemming from its sequence of Gly-His-Lys (GHK). It is purportedly found as a sequence in type 1 collagen and may signal that there is collagen breakdown to various dermal cells. Consequently, this... KEDP Potential on Gene Activation and Cellular Aging
KEDP, also referred to as Prostamax, is a synthetic tetrapeptide carrying the sequence Lys-Glu-Asp-Pro and belongs to the family of short bioregulators associated with the work of Khavinson. Investigators have positioned it as a candidate for tissue-specific repair... N-Palmitoylrigin Actions on Integrity and Repair of Cellular Systems
N-Palmitoylrigin (also known as Palmitoyl Tetrapeptide-7) is a short synthetic peptide with the sequence glycyl-glutamyl-prolyl-arginine, commonly abbreviated GQPR. Laboratory descriptions of the molecule generally frame it as a candidate regulator of extracellular...
Sermorelin & GHRP-6 & GHRP-2 Blend: Anabolic Potential and Synergism
Sermorelin, GHRP-6, and GHRP-2 are synthetic peptides that are under investigation regarding their potential to interact with various receptors on anterior pituitary cells and stimulate the release of growth hormone. Structurally, Sermorelin appears to be a fragment... Sermorelin & GHRP-6: A Research Perspective on Dual-Pathway Pituitary Stimulation
Researchers suggest that anterior pituitary cells may be prompted to release growth hormone through more than one signaling route. Specifically, this may be prompted by combinations of peptides such as Sermorelin and GHRP-6, as they appear to interact with the same... Thymogen Potential in Immune Cell Regulation
Thymogen appears to be a synthetic dipeptide composed of the two amino acids L-glutamine and L-tryptophan (Glu-Trp). It was originally identified by a team of researchers led by Khavinson et al., and thus it is considered to be one of Khavinson’s peptides.(1) The... CJC-1295 & Hexarelin Blend Potential for Growth Hormone Signaling Stimulation
Researchers investigating growth hormone (GH) regulation in mammalian research models may consider experiments combining peptides that engage somatotroph cells of the anterior pituitary through complementary receptor systems. Two such peptides are CJC-1295 (Mod GRF... Oxytocin Actions On Neuronal Circuits in Different Mammalian Research Models
Oxytocin is posited to be a cyclic nonapeptide composed of nine amino acids in the sequence Cys–Tyr–Ile–Gln–Asn–Cys–Pro–Leu–Gly-NH2 (CYIQNCPLG-NH2), with a molecular weight of approximately 1007 Da. Structurally, it appears to consist of a six-residue ring stabilized...
