Vaginal atrophy affects up to 50% of postmenopausal women. Research into BPC-157 and GHK-Cu explores whether peptides that support mucosal repair and collagen synthesis could play a role in mucosal health research.
Ipamorelin, Sermorelin, and CJC-1295 all stimulate growth hormone but through different receptors, with different half-lives, and different GH release patterns. This comparison explains how each works and when each is used in research.
Premature ejaculation involves complex neurobiological pathways that peptides like PT-141 and Kisspeptin may interact with. This article reviews the current research — what’s known, what’s theoretical, and what the gaps are.
Varicocele is the most common correctable cause of male infertility. Research into BPC-157, TB-500, and Gonadorelin explores whether peptides can address the inflammation, oxidative stress, and hormonal disruption varicocele causes.
What Is Vasoactive Intestinal Peptide (VIP)? Vasoactive intestinal peptide (VIP) is a 28-amino-acid neuropeptide belonging to the secretin/glucagon superfamily.
What Is Melanotan II? Melanotan II (MT-II) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH), a naturally occurring neuropeptide involved in the regulation of melanogenesis, appetite, and sexual function.
What Is Kisspeptin-10? Kisspeptin-10 is a synthetic decapeptide corresponding to the C-terminal 10 amino acids (residues 112-121) of the full-length kisspeptin protein, also known as kisspeptin-54 or metastin.
Peptides and steroids are both studied for muscle and body composition research but work completely differently. This comparison covers mechanisms, evidence quality, and risk profiles for each approach.
Male hypogonadism affects millions of men. Research into Gonadorelin, Kisspeptin-10, and Sermorelin explores whether peptides can support the HPG axis and preserve fertility in ways TRT cannot.
Perimenopause disrupts the HPG axis long before menopause. Research into Kisspeptin-10 and PT-141 explores how peptides may influence the hormonal signaling pathways affected during this transition.
