Kisspeptin-10: Master upstream regulator of the reproductive axis — the GnRH releaser. Typical dose 50-200 mcg. Oxytocin: The "bonding hormone" — neuropeptide with established obstetric and exploratory social roles. Typical dose 24-40 IU (intranasal) mcg. Both fall under the Sexual Health category.
Stacking Kisspeptin-10 with Oxytocin is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.
Kisspeptin-10 is typically dosed: Once or twice daily (SubQ) for Libido / HPG axis stimulation; Single dose 36 hours pre-collection for IVF trigger (clinical, IV). Oxytocin is typically dosed: As needed, typically 30-45 min before relevant activity for Intranasal social/research; As needed for Subcutaneous wellness; Titrated infusion for Obstetric (clinical IV).
Kisspeptin-10: Not FDA approved as a therapeutic. Oxytocin: FDA approved as injectable Pitocin for obstetric indications since the 1960s. Intranasal oxytocin not FDA-approved as therapeutic; available via compounding pharmacies.
