Description
The PT-141 spray from LA Peptides is a ready-to-use nasal spray holding 10mg of PT-141 in a 10ml bottle. It’s already in solution, so there’s no powder to reconstitute. Made for laboratory research only.
What’s in the PT-141 spray?
PT-141 (bremelanotide) is a cyclic heptapeptide that acts on MC3 and MC4 melanocortin receptors in the brain. It was developed from Melanotan II.
Unlike most compounds studied for sexual function, it works in the central nervous system, not on blood flow. That’s what made it interesting in the first place.
PT-141 acts on melanocortin receptors in the brain. It doesn’t work through blood flow, so the delivery route is a real research question. The spray gives you a premixed, consistent solution for intranasal work.

Why choose a nasal spray format?
A spray is the fastest way to get started. The peptide is already dissolved at a known concentration, so there’s no weighing, no mixing and no risk of a bad reconstitution. Every pump delivers a fixed volume.
Powder in a vial still keeps longer and gives you more control over concentration, so for long studies a vial can make more sense.
Prefer powder? Take a look at PT-141 10mg. The PT-141 10mg vial costs $69.99, against $59.99 for this spray, so the choice usually comes down to convenience versus flexibility.
Research background
Palatin Technologies developed it from Melanotan II after researchers noticed side effects in the original tanning studies. An injectable version was approved by the FDA in 2019 under the name Vyleesi, for a specific condition in premenopausal women.

How to store the PT-141 spray
Keep the bottle upright in the fridge with the cap on. Before the first use, prime the pump with a few sprays into a tissue until you get a fine, even mist. Wipe the tip after each use so nothing builds up.
Use it within about 30 days of opening, and don’t swap nozzles between bottles.

Keeping track of a spray bottle
Write the date you opened the PT-141 spray on the label. Note how many pumps you use per session and how many went into priming, so you know roughly how much is left. If the pump delivers about 0.1ml per press, a 10ml bottle gives around 100 presses, so a simple tally tells you when to reorder.
Keep the lot number in your notes too. If you switch to a new bottle partway through a study, you’ll know which results came from which batch.
Common mistakes with nasal sprays
The usual ones are skipping the priming step, storing the bottle on its side so the tube draws air, and leaving it out of the fridge between sessions. Each of these changes how much solution comes out per press, which makes results harder to compare.
