Kisspeptin-10 is the "master switch" research peptide for the reproductive hormone system. It sits at the very top of the hormonal chain and signals downstream neurons to release the hormones that ultimately drive LH, FSH, testosterone, and estrogen release.

ProSource Labs supplies KISSPEPTIN-10 in the following available vial sizes: 5mg. Each KISSPEPTIN-10 vial contains pure lyophilized peptide — no fillers, no bulking agents. Product SKU references: KISSP-10MV.

• Reproductive Axis: Master trigger for the hormonal chain that produces LH, FSH, and sex hormones
• Short & Active: Just the last 10 amino acids of the parent KISS1 protein — full activity retained
• Upstream of GnRH: Sits ABOVE GnRH in the reproductive signaling hierarchy
• Puberty Research: Central research tool in reproductive-development studies

Batches are characterized by ESI mass spectrometry to confirm molecular weight against the theoretical value, with amino-acid sequence confirmation on selected QA lots. Peptide content assay distinguishes net peptide mass from residual counter-ion salt.

Lyophilized KISSPEPTIN-10 vials should be stored at -20°C (or colder) in a laboratory freezer, inside the sealed factory container. Minimize warm-up cycles — move only the specific vial needed for a given experiment out of frozen storage at a time.

All laboratory handling of KISSPEPTIN-10 should follow the receiving institution's SOPs and applicable peer-reviewed protocols relevant to the researcher's specific experimental question. ProSource Labs does not publish end-user preparation or usage instructions.

Every batch of KISSPEPTIN-10 released by ProSource Labs undergoes independent reverse-phase High Performance Liquid Chromatography (HPLC) — the industry-standard analytical method for this class of research compound. Target chromatographic purity is typically ≥ 99%.

Additional characterization may include ESI mass spectrometry for molecular weight confirmation, Karl Fischer titration for residual moisture, and appearance/solubility inspection. A batch-specific Certificate of Analysis (COA) is available on request through customer support after purchase.

Each production lot of KISSPEPTIN-10 is quarantined pending analytical release, tested against documented purity, identity, and moisture acceptance criteria, and only released to sellable inventory after passing every QA checkpoint. Batches that fail any single criterion are quarantined and never reach customer-facing inventory.

If a vial of KISSPEPTIN-10 you received from ProSource Labs ever fails your own institution's incoming QA testing, contact customer support at support@prosourcelabs.org — we retain samples of every batch for cross-verification.

Research and lab work on the reproductive endocrine axis, GnRH neuron activation, and puberty/fertility research. It's the upstream trigger of the entire hormonal reproductive cascade.

KISSPEPTIN-10 vials ship in tamper-evident, moisture-resistant, cold-chain-friendly outer packaging from our Southern California distribution facility for fast US domestic delivery — typically 2-4 business days coast-to-coast, with expedited options available at checkout.

Every KISSPEPTIN-10 shipment is discreet — the outer packaging carries no product-specific branding or direct reference to the compound name inside, protecting researcher privacy. Tracking numbers are emailed automatically. For institutional or high-volume orders, dedicated wholesale pricing is available through the wholesale portal.
