What it is claimed to help

What the human evidence actually is

Real, and worth reading honestly. The RECONNECT trials led to FDA approval in 2019 for hypoactive sexual desire disorder in premenopausal women. The effect size was statistically significant and clinically modest. Development for erectile dysfunction was abandoned earlier over blood pressure increases with intranasal dosing.

How it is supposed to work

Non-selective melanocortin receptor agonist acting centrally at MC4R on sexual desire pathways — a brain mechanism, not a vascular one like PDE5 inhibitors.

Safety

Nausea is very common. Transient blood pressure increase and heart rate reduction; contraindicated in uncontrolled hypertension or known cardiovascular disease. Focal hyperpigmentation with repeated use.

Storage and handling

Lyophilised peptide is generally stored at 2–8 °C, or below −20 °C for long-term storage. Reconstituted in bacteriostatic water (0.9% benzyl alcohol) a solution is typically treated as usable for about 28 days refrigerated, versus roughly 24 hours for plain sterile water, which has no preservative. Add the water slowly down the vial wall and swirl — never shake, which shears peptide chains and foams the solution.
