Pure Peptides Review & Prices

AOD-9604 is a modified fragment of human growth hormone (amino acids 176-191 with an added tyrosine). It was developed to study growth hormone's effect on fat breakdown without its effects on growth or blood sugar, and reached human weight-loss trials before development stopped.

ARA-290 (cibinetide) is an 11-amino-acid peptide designed from part of erythropoietin (EPO). It targets the innate repair receptor to study tissue-protective and anti-inflammatory effects, without EPO's effect of raising red blood cell counts.

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.

CJC-1295 is a member of the GHRH analogue family of peptides and consists of a sequence derived from hGRF(1-29). The addition of a DAC group allows for prolonged exposure by binding to albumin compared to native GHRH. That longer exposure is what makes CJC-1295 interesting in human pharmacology. Studies have followed changes in GH and IGF-1 , along with the pharmacokinetic behavior of the DAC form. At Peptide Grading , CJC-1295 listings can be compared by material form, supplier, reported specifications, COA documentation, quantity, shipping and price per mg.

A nonapeptide studied for sleep architecture, stress response and neuroendocrine signaling, with mixed human evidence.

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.

GHRP-6 (growth hormone releasing peptide-6) is a synthetic hexapeptide that stimulates growth hormone release by activating the ghrelin receptor. It is one of the earliest growth hormone secretagogues and is known for strongly increasing appetite.

Hexarelin (examorelin) is a synthetic hexapeptide in the growth hormone releasing peptide (GHRP) family, studied for growth hormone release through ghrelin receptor activation. Compare research vendor listings by vial size, price per mg and batch COAs on Peptide Grading .

Ipamorelin is a five-amino-acid peptide that switches on the ghrelin receptor and makes the pituitary release growth hormone. Novo Nordisk researchers built it in the 1990s, and what made it interesting was how narrow its effect looked. Older compounds in the same family pushed up other hormones too. Ipamorelin mostly didn't. It has no approved use anywhere. A Phase 2 trial in the early 2000s tried it for a bowel problem after surgery, and it didn't work well enough to continue. So what's left is mostly lab and animal data, and the research-labeled vials that vendors sell. On Peptide Grading , we list those vials with vendors, sizes, price per mg, and COA documents in one place, so you can compare them without hunting through tabs.

KPV is a tripeptide (lysine-proline-valine) taken from the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH). It is studied for its anti-inflammatory signalling, mainly in cell and animal models of inflammatory bowel conditions.
