What you are paying for with Kisspeptin
Kisspeptin is a neuropeptide encoded by the KISS1 gene that is a key upstream regulator of the reproductive hormone axis. It is studied for its reported ability to stimulate gonadotropin-releasing hormone (GnRH) and downstream hormone signaling. Because of that, the cost of Kisspeptin reflects more than raw material. Kisspeptin research focuses on activation of GnRH neurons, which drives luteinizing-hormone signaling and the broader reproductive axis - a model for fertility and hormone research.
What drives Kisspeptin pricing
Three things move the price of Kisspeptin most. First, vial size: Kisspeptin is cataloged in 5 mg vial, 10 mg vial, and a larger vial holds more peptide, so it costs more per unit even at the same per-mg rate. Second, purity and testing: genuine third-party verification to a 99%+ target with a Certificate of Analysis is a real production cost, and it is what makes a research result trustworthy. Third, quantity: ordering Kisspeptin in bulk or on a recurring research schedule lowers the effective per-vial cost.
Cost per milligram
Comparing peptides on price alone is misleading because vial sizes differ. The fair comparison is cost per milligram of verified peptide. When you evaluate Kisspeptin, divide the vial price by its milligram content and compare like-for-like against other 99%+ third-party-tested material - not against unverified powder that happens to be cheaper.
Getting the best value on Kisspeptin
Kisspeptin can be ordered as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months), and bulk or standing-order pricing is available for research programs. The best value is not the lowest sticker price - it is the lowest cost per milligram of documented, third-party-tested Kisspeptin, which is the standard every Peptides Factory Direct lot is held to.
Frequently asked questions
How much does Kisspeptin cost?
Kisspeptin typically ranges from $45 to $130 per vial at research-market pricing, depending on vial size. All Peptides Factory Direct Kisspeptin is third-party tested to a 99%+ purity target with a COA on request. Research use only.
Why does Kisspeptin pricing vary between suppliers?
Differences come down to purity and documentation. Material with genuine third-party COAs, lot tracking, and identity confirmation costs more to produce than unverified powder. The fair comparison is cost per milligram of verified peptide, not sticker price.
Is cheaper Kisspeptin a good deal?
Not if it lacks a Certificate of Analysis. Across the research-supply market the strongest trust signal is verifiable third-party purity testing. Unverified Kisspeptin can cost far more in failed experiments than the few dollars it saves.
Can I get bulk pricing on Kisspeptin?
Yes. Kisspeptin is available for one-time or recurring research orders, and bulk or standing-order pricing is available for research programs - note it on your order or open the portal.
