MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded by a short open reading frame in the mitochondrial 12S rRNA region. Peptide Grading tracks MOTS-c vendors, quantities, prices, shipping details, and COA information to make research-product listings easier to compare.

Tesamorelin is a synthetic 44-amino-acid analogue of human growth hormone-releasing factor (GRF). The peptide carries an N-terminal hexenoyl group, a structural change that distinguishes it from native GRF while retaining activity at the GRF receptor. Tesamorelin has been studied extensively in human endocrine research, particularly in work involving growth hormone release and IGF-1 response. Peptide Grading compares current listings by supplier, quantity, stated specifications, COA availability, shipping, and price per mg.

Retatrutide is an experimental once-weekly injection from Eli Lilly (internal code LY3437943). It's a single molecule that activates three receptors: GIP, GLP-1, and glucagon. Tirzepatide covers the first two, and retatrutide adds the third. It isn't approved anywhere, for anything. Lilly has said it plans to file with the FDA in the first quarter of 2027. On Peptide Grading , we list the research-labeled vials with sizes, price per mg, and COAs side by side. Being listed there isn't an endorsement, and those vials aren't Lilly's product.

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

If you've ever seen a blue-tinted skincare serum, you've already met GHK-Cu. It's a copper-carrying tripeptide that was first pulled out of human blood plasma back in 1973, and it's been sitting in cosmetics for decades. What's newer is its life as a research peptide: vials of it, and blends like Glow and Klow that put it alongside BPC-157 and TB-500 . I'll say upfront that GHK-Cu is a bit unusual in this catalog. It has a long research history, and the skin-care version is a mainstream cosmetic ingredient. But no GHK-Cu drug is approved by the FDA, and the injectable side is much less studied than the creams. On Peptide Grading , we line up the research-labeled listings, with vendors, sizes, price per mg, and COAs , so you can see the differences. A listing isn't a recommendation to use it.

Tirzepatide is a first-in-class dual GIP and GLP-1 receptor agonist developed by Eli Lilly, FDA-approved for type 2 diabetes (Mounjaro) and chronic weight management (Zepbound) including severe obstructive sleep apnea in adults with obesity. It is a 39-amino-acid peptide with a C20 fatty di-acid moiety that promotes albumin binding, enabling once-weekly dosing. Clinical trials consistently demonstrate it delivers the most substantial weight reduction among incretin-based therapies, with up to 22.5% mean body weight loss at 72 weeks.

BPC-157 is a 15-amino-acid peptide first described from gastric juice. Most of the published work is preclinical, with studies covering tendon, muscle, gastrointestinal, vascular, and other injury models. Researchers have looked at several signaling pathways, including VEGFR2, nitric oxide, Akt-eNOS, and ERK1/2 . Other work has focused on angiogenesis, fibroblast activity, endothelial responses, and inflammation. Human data are still sparse. Small studies have looked at knee pain, interstitial cystitis, and intravenous safety and pharmacokinetics , but the number of human studies remains small and larger controlled trials are not available.

IGF-1 LR3, also called Long R3 IGF-1 , is a recombinant analogue of human insulin-like growth factor 1. Its structure combines a 13-amino-acid N-terminal extension with an arginine substitution at position 3 of the mature IGF-1 sequence. These changes were designed to alter how the molecule interacts with IGF-binding proteins while retaining activity at the IGF-1 receptor. Research has therefore used IGF-1 LR3 as a tool for studying IGF signaling, cell growth, protein synthesis, and growth-factor biology.

Klow Stack is Glow plus KPV: four peptides ( GHK-Cu , BPC-157 , TB-500 , KPV) in one vial. Each one is researched for a different job, from tissue remodeling to inflammation. The catch is that the research is on the peptides individually, mostly in animals. Nobody has published results on the blend itself. Klow packs them into a single product instead of four separate vials. On Peptide Grading , we track Klow Stack listings in one place: vendors, vial sizes, price per mg, shipping details, and certificate of analysis (COA) documents, so you don't need ten tabs open to compare them.

5-Amino-1MQ is a small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT) . Unlike peptide compounds, it is a quinolinium-based molecule studied mainly in cell and animal models to understand NNMT activity, methylation metabolism, and related NAD+ pathways. Current evidence remains preclinical , with no established human clinical profile.
