PT-141 Nasal Spray Price Comparison — Verified Vendors & Lab-Tested COAs

How much does PT-141 Nasal Spray cost per month?

The cheapest verified PT-141 Nasal Spray protocol works out to about $10.61 per month: Ascension Peptides's 10 mg bottle at $24.50 with code WPA, dosed at 1 mg once weekly (the most-common community protocol). One bottle provides 10.0 doses — about 10.0 weeks of supply at this cadence — so the per-week cost is roughly $2.45, which works out to $10.61 on a 4.33-week month. This protocol is derived from 506 verified PT-141 calculator runs logged by the WPA community. Cost scales roughly linearly with the per-spray dose and weekly frequency you choose.

PT-141 Nasal Spray COA Coverage Across Tracked Vendors

4 of the 5 tracked PT-141 Nasal Spray listings (80%) publish a third-party Certificate of Analysis. Assayed purity on those reports ranges from 98.00% to 99.26%. 4 listings report more PT-141 in the bottle than the label claims, which lowers the real cost per milligram below the printed price. The most recent PT-141 Nasal Spray COA on file is dated 5/26. The remaining 1 listing has no published report, so its purity is the vendor's own claim.

A COA is only worth what it proves: it has to name the independent lab, be dated within the last 12 months, and match the exact PT-141 Nasal Spray batch and bottle size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose PT-141

Across 506 PT-141 calculator runs logged by the WPA community, the most common dose entered is 1mg, most often once weekly. The size researchers calculate against most often is the 10mg bottle (487 runs). The most common bacteriostatic water volume is 2mL, which is what sets the draw marks on the syringe for that dose. At that dose a 30mg bottle yields roughly 30 doses, so the bottle size you buy decides how often you reorder as much as the price does.

PT-141 Nasal Spray Discount Codes

5 of the 5 tracked PT-141 Nasal Spray listings carry a WPA researcher discount code. The largest live discount is 50% off. Every price and per-milligram figure on this page is the post-discount number, so you are never comparing a discounted listing against an undiscounted one. Codes change and some exclude sale items or carry order minimums.

About PT-141

PT-141 (bremelanotide) is a melanocortin research peptide most often sourced for libido and sexual-function research. It is the same molecule sold as the FDA-approved drug Vyleesi, and ships as a lyophilized powder you reconstitute with bacteriostatic water before use.

Its reported half-life is ~2.7 hours, which is the main reason the community cadence above looks the way it does. FDA-approved as Vyleesi (bremelanotide injection) for premenopausal HSDD, June 2019.

Reading PT-141 Nasal Spray Listings

Nasal spray listings are ranked on total PT-141 per bottle, so a lower-priced bottle at a lower concentration can still be the more expensive option per milligram. Where a vendor publishes it, the mcg or mg delivered per spray is what determines how many doses a bottle actually contains.

A nasal spray COA should confirm the active ingredient's purity, and — where available — the preservative system and pH range, which do not appear on a vial COA. Intranasal delivery differs from injection in absorption kinetics, so vial protocols do not carry over.
