Thymogen Potential in Immune Cell Regulation
Jul 17, 2026
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
Jul 8, 2026
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
Jun 30, 2026
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...
Kisspeptin 45-54 Peptide Interactions with Hypothalamic and Neuronal Cells
Jun 19, 2026
Kisspeptin 45-54 is posited to be a synthetic, 10–amino acid research peptide that is also referred to as kisspeptin 10. It may correspond to residues 45–54 of the parent kisspeptin precursor, and its sequence appears to be Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH2....
T-31 Peptide Interactions with Cellular Aging, Renewal, and Stress Pathways
May 28, 2026
T-31 is posited to be a synthetic, three–amino acid research peptide consisting of the sequence Ala-Glu-Asp (AED), and is also sometimes referred to in the literature as Cartalax. Structurally, it appears to belong to the family of so-called Khavinson’s short...
PNC-27 Peptide Interactions with Different Tumor Cell Lines
May 20, 2026
PNC-27 is posited to be a synthetic, 32–amino acid research peptide composed of two main segments. Specifically, its N-terminus appears to be made of a p53-derived HDM-2–binding sequence which represents the 12-26th residue of p53. On the other hand, its C-terminal...
Tesamorelin’s Potential for Anabolic and Catabolic Signaling in Cells
May 11, 2026
Tesamorelin is considered to be a synthetic analog of growth hormone-releasing hormone (GHRH), designed to activate GHRH receptors in pituitary gland cells. The peptide consists of the full 44-amino-acid sequence matching endogenous GHRH but includes key modifications...
Pal-AHK Interactions with Follicular Cells Growth and Apoptosis
May 6, 2026
Pal-AHK appears to be a tripeptide with the sequence alanine–histidine–lysine, which has been palmitoylated via a C16 fatty acid chain to the N-terminus of the sequence.(1) The peptide sequence appears to have a high affinity to copper ions, while the palmitoylation...
Interactions Between PE-22-28 and Nerve Cells
Apr 30, 2026
PE-22-28 is a 7-amino-acid peptide derived from the degradation products of spadin (PE 12-28), which itself originates from the post-translational maturation of sortilin. Researchers have posited that the peptide may act primarily through a TREK-1 blockade, and data...
