Hormonal & Sexual Health

Restores natural testosterone production and testicular function. 10,000 IU vial. Human Chorionic Gonadotropin (hCG) is a heterodimeric glycoprotein hormone composed of an alpha subunit shared with luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH), paired with a unique beta subunit. It binds the LH/hCG receptor (LHCGR) and has been widely used as a research tool to study gonadotropin receptor signal transduction, Leydig cell steroidogenesis, and corpus luteum maintenance in animal models. This preparation is provided as a lyophilized powder with stated biological activity in International Units for in vitro and ex vivo research use only.

Upstream hormone trigger for LH/FSH and natural reproductive signaling. 10mg. Kisspeptin-10 is a decapeptide — a chain of ten amino acids — with the sequence Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH₂. It is the shortest bioactive fragment of the kisspeptin-54 protein, which is encoded by the KISS1 gene, first identified in 1996 at Pennsylvania State University. The peptide has the molecular formula C₆₃H₈₃N₁₇O₁₄, a molecular weight of 1302.45 g/mol, and CAS number 374675-21-5. The C-terminal amide group on the final phenylalanine is a defining structural feature that distinguishes it from truncated kisspeptin variants. Supplied as a white lyophilized powder with purity of 98% or higher by HPLC, highly soluble in bacteriostatic water. Store refrigerated at 2–8 °C. This product is strictly for research purposes only. Not approved for human or animal use.

Bremelanotide for libido and arousal, works on desire not just blood flow. 10mg. PT-141 (bremelanotide) is a synthetic cyclic heptapeptide belonging to the melanocortin peptide family. It was derived from the research compound Melanotan II and first described in the early 2000s. The molecule features a lactam bridge — a cyclic bond between amino acid side chains — that constrains it into a ring shape. It has the molecular formula C50H68N14O10, a weight of 1,025.2 g/mol, and CAS number 189691-06-3. Classified as a melanocortin receptor ligand, it is structurally related to compounds in the MC1R through MC5R family. Supplied as a white to off-white lyophilized powder, soluble in water. This product is strictly for research purposes only.
