Vial kit. Oxytocin 20 mg, PT-141 20 mg, Kisspeptin-10 20 mg and Bacteriostatic Water 10 ml. For laboratory research use only.

PT-14120 mg

KLIKPT141 contains PT-141 (Bremelanotide), a synthetic cyclic heptapeptide analogue of alpha-MSH derived from Melanotan II. Each pen contains 10mg/2ml. It acts as a non-selective agonist at melanocortin receptors MC1R, MC3R, MC4R, and MC5R. Research focuses on its mechanism of action through the central nervous system rather than the vascular system, distinguishing it from other compounds in related research areas. It was FDA-approved in 2019 under the brand name Vyleesi.

Kisspeptin-1020 mg

KLIKPEPTIN contains Kisspeptin-10, the minimal bioactive fragment of the kisspeptin family. Each pen contains 10mg/2ml. Kisspeptins are products of the KISS1 gene and act on the KISS1R (GPR54) receptor in the hypothalamus to stimulate gonadotropin-releasing hormone (GnRH) neurons. Research focuses on its role as the master regulator of the hypothalamic-pituitary-gonadal axis, puberty onset, fertility, and reproductive hormone regulation.

Bacteriostatic Water10 ml

Store at 2–8°C, do not freeze.

For laboratory research use only. Not for human or veterinary administration.

Frequently asked questions

Orders are dispatched in insulated, temperature-controlled packaging with cold packs where required. Tracked delivery is £20 everywhere. Free delivery on orders of £300 or more. Tracked UK delivery typically arrives within 1–3 working days. If the packaging arrives damaged or warm, contact us within 24 hours and we will arrange a replacement batch.

Products with an inspected external report list the report ID, tested compound and amount, source laboratory, measured purity where reported, and a link to the external record. A report applies only to that tested sample and does not verify every variant or future batch.

Follow the product label, supplied documentation and your validated laboratory protocol. Storage requirements can vary by compound and presentation, so no single temperature or duration applies to the whole catalogue.

Use only the diluent, concentration, aseptic process and stability window defined by your validated protocol and the applicable product documentation. Apex does not publish one universal reconstitution instruction for every compound.

Because products are perishable and supplied for research use, they are non-returnable once dispatched, unless the cold chain has been broken or the batch is defective — in which case we will replace it. See our shipping and returns policy for full terms.

No. All products are supplied strictly for laboratory research use only, and must not be administered to humans or animals. Orders are screened accordingly.
