Retatrutide
Retatrutide is a first-in-class investigational triple hormone receptor agonist (GIP, GLP-1, and glucagon) developed by Eli Lilly. In the Phase 2 trial (Jastreboff et al., NEJM 2023, n=338), the 12 mg dose achieved 24.2% mean body weight reduction at 48 weeks, with 100% of participants achieving at least 5% weight loss. Multiple Phase 3 TRIUMPH trials are ongoing, with TRIUMPH-4 (Dec 2025) reporting average loss up to 71.2 lbs with osteoarthritis pain relief. Expected FDA approval is 2027-2028.
BPC-157 is a synthetic 15-amino-acid peptide (sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, MW ~1419.5 g/mol) derived from a protein found in human gastric juice. It has demonstrated robust regenerative and cytoprotective effects across hundreds of animal studies spanning tendon, ligament, muscle, bone, nerve, GI tract, and blood vessel healing. However, human clinical data is extremely limited — only three pilot studies have examined BPC-157 in humans as of 2025 (knee pain n=16, interstitial cystitis n=12, IV safety n=2). The FDA classifies it as Category 2, prohibiting compounding, and WADA bans its use in sports.
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) found in human plasma, saliva, and urine. First discovered by Dr. Loren Pickart in 1973, plasma levels average 200 ng/mL at age 20 but decline to ~80 ng/mL by age 60. It has been extensively studied for wound healing, collagen synthesis, skin regeneration, and gene modulation, with decades of cosmetic use and a broad safety profile. Molecular weight is approximately 340 g/mol (as the copper complex), with the formula C14H24N6O4Cu.
Ipamorelin is the most selective growth hormone secretagogue (GHS) available, a synthetic pentapeptide (MW ~711.86 g/mol, formula C38H49N9O5) that stimulates pulsatile GH release from the pituitary gland without significantly affecting cortisol, prolactin, or appetite. It is widely regarded as the mildest GHS, making it popular in anti-aging, body composition, and recovery contexts. However, research on ipamorelin is limited, and it is not FDA-approved for any indication.
KLOW is a research peptide blend containing GHK-Cu, BPC-157, TB-500, and KPV. Its individual components have been studied in preclinical research involving tissue repair, cellular signaling, and inflammatory pathways, but the complete blend has not been clinically validated.
A BPC-157 and TB-500 blend, often called the "Wolverine Stack" is an informal combination of two synthetic peptides studied for tissue repair, cellular movement, and recovery
Cagrilintide is a long-acting synthetic analog of human amylin, a peptide hormone co-secreted with insulin by pancreatic beta cells. It is being developed by Novo Nordisk both as a standalone agent and in fixed-dose combination with semaglutide (CagriSema). The CagriSema combination targets complementary appetite pathways — amylin acts on hindbrain satiety circuits while GLP-1 acts on hypothalamic and gut pathways. In the REDEFINE Phase 3 program, CagriSema achieved 20.4% weight loss at 68 weeks. Novo Nordisk filed for FDA approval in 2026.
MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino-acid mitochondrial-derived peptide (MDP) encoded within the mitochondrial 12S rRNA gene (MT-RNR1). Discovered in 2015 by Lee et al. at USC, it acts as a metabolic regulator primarily through AMPK activation. In mouse models, MOTS-c prevents diet-induced obesity and insulin resistance, enhances exercise capacity (old mice ran 2x longer on treadmill tests), and reduces age-related metabolic decline. A modified analog (CB4211) showed good tolerability in a Phase 1 human trial. No clinical trials of native MOTS-c in humans have been completed.
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro, MW ~751.89 g/mol) developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is a structural analogue of the immunomodulatory peptide tuftsin with an added Pro-Gly-Pro sequence for stability. Approved in Russia as an anxiolytic and nootropic nasal spray, it crosses the blood-brain barrier to enhance GABAergic neurotransmission, modulate monoamine systems, and regulate neuropeptide Y signaling. A 2008 study of 62 patients with GAD showed Selank comparable to medazepam for anxiety reduction but with no sedation, cognitive impairment, or dependence risk. Half-life is approximately 2-10 minutes.
