Buying & shipping FAQ

What you need to know before ordering hormonal vials.

Kisspeptin-10 5 mg or 10 mg?

10 mg at $89.99 = $8.99/mg vs $10.80/mg for the 5 mg. If you're committing to a Kisspeptin-10 protocol, 10 mg is the better buy.

Can oxytocin be taken orally?

No — oral bioavailability is effectively zero. Use sublingual drops or intranasal sprayer. Ships as lyophilized powder.

Gonadorelin vs Kisspeptin-10?

Both drive LH/FSH but at different points. Gonadorelin is a direct GnRH analogue at the pituitary. Kisspeptin-10 acts upstream at hypothalamic GnRH neurons.
