What is — PT-141
PT-141, also known as bremelanotide, is a synthetic cyclic peptide supplied by Peptworks as a lyophilized 10 mg vial strictly for laboratory Research Use Only (RUO). It is an analogue related to the melanocortin (Melanotan) family and is listed here under the Tanning/melanocortin category. It is not a medicine, supplement, cosmetic or medical device, and is not intended for human or animal consumption. Peptworks makes it available to B2B buyers as bulk unbranded vials (white-label), all from stock already located inside the EU.
In research models, PT-141 (bremelanotide) is described as a non-selective agonist at melanocortin receptors, with reported activity at MC1R, MC3R and MC4R. MC1R signaling is studied in the context of melanin and pigmentation pathways, while central MC3R/MC4R signaling is investigated in rodent models of appetite, energy homeostasis and behavior. Every mechanistic statement here refers strictly to in-vitro systems and animal research, not to human use.
Research
- Melanocortin receptor (MC1R/MC3R/MC4R) binding and signaling assays
- Pigmentation and melanogenesis pathway research in vitro
- Central melanocortin pathways in rodent behavioral models
- Appetite and energy-homeostasis signaling research
- Comparative studies within the melanocortin / Melanotan peptide class
- Peptide solubility, stability and formulation studies
Advantages
- >=98% HPLC purity with an independent per-batch CoA, supporting reproducible in-vitro and preclinical work
- Lyophilized 10 mg format that reconstitutes readily for laboratory research protocols
- Well-characterized melanocortin receptor agonist, useful as a reference compound in receptor-binding and signaling assays
- EU-held stock enabling fast intra-community resupply for ongoing research programs
- Available bulk or white-label, simplifying research-reagent catalog expansion for B2B resellers
Safety
- Research literature on bremelanotide describes transient increases in blood pressure alongside reductions in heart rate in preclinical models
- Nausea is among the most frequently reported observations in the research literature
- Flushing and headache have been reported
- Transient focal hyperpigmentation / skin darkening has been reported in melanocortin-pathway research
- Yawning and, in animal behavioral models, spontaneous penile erection have been reported
Ideal for
- Melanocortin receptor (MC1R/MC3R/MC4R) pharmacology and binding studies
- Reference / standard compound in in-vitro signaling assays
- Preclinical central-melanocortin pathway research in animal models
- Peptide formulation, stability and reconstitution R&D
- B2B resellers building a bulk or white-label research-peptide catalog for the EU market

Frequently asked questions
Where can I buy PT-141 in bulk in the EU?
Peptworks is a B2B wholesale and white-label supplier of PT-141 (Bremelanotide) 10 mg, shipped from stock already inside the EU. Orders move intra-community in 3-5 business days with no customs. Orders start from a 4-vial pack per reference.
What is the wholesale PT-141 price per vial?
PT-141 10mg has two public per-vial prices: €35.90 in a 4-vial pack and €22.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs.
Do you offer PT-141 as white-label?
Yes, in the white-label sense: PT-141 comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order for PT-141?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the PT-141 Certificate of Analysis verified?
Every box carries the Peptworks label plus a unique QR code linking to that specific batch's Certificate of Analysis, verified through Peptworks. Each CoA is independent and per batch, covering HPLC identity/purity (>=98%) and heavy metals, so resellers and their customers can confirm exactly what shipped.
How do payment and shipping work for B2B orders?
Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees. there is no card checkout on the site.
