Melanocortin-receptor research peptide and essential reconstitution supplies for the laboratory. COA-backed, US-shipped, and supported by our handling guides.
This category pairs a melanocortin-receptor research peptide with the bench supply most labs need to work with any lyophilized reagent. Both are supplied strictly for laboratory research. For research use only — not for human consumption. The description of PT-141 below reflects only how it is characterized in the research literature and makes no claim about effects in people.
PT-141 (bremelanotide) is a synthetic melanocortin peptide that has been investigated in research models for its activity at melanocortin receptors, particularly MC4R. It is a standard reference compound in melanocortin-signaling assays, and laboratories that buy PT-141 for research receive a lyophilized powder qualified against a batch COA. As with every peptide we stock, it is a research chemical only.
Bacteriostatic water is a reconstitution supply, not a peptide. It is water containing a low concentration of benzyl alcohol as a bacteriostatic agent, used in the laboratory to dissolve lyophilized powders for study. Stocking it alongside PT-141 lets a lab prepare working solutions without sourcing the diluent separately. See the reconstitution guide for how solvent choice affects a research preparation.
Our peptides are independently analyzed before they reach inventory: HPLC confirms purity against a ≥99% target and mass spectrometry confirms identity, with results on a batch-specific Certificate of Analysis. Each PT-141 vial is traceable to its source lot so it can be qualified before use. The COA reading guide explains how to verify the reported mass matches the sequence you ordered. Supplies such as bacteriostatic water are quality-checked appropriately for their role as reconstitution media.
Keep lyophilized PT-141 cold, sealed and out of light; reconstitute only what a protocol needs and aliquot the rest to avoid repeated freeze-thaw. Bacteriostatic water should be stored per its label and used within its stated in-use window once opened. The storage & handling page details cold-chain expectations from arrival to bench, and the reconstitution guide walks through mixing a powder into a stable working solution.
No — it is a reconstitution supply used to dissolve lyophilized peptides for laboratory study.
It is investigated in research models for its activity at melanocortin receptors; it is a research chemical and not a treatment.
That depends on the target concentration of your protocol — the reconstitution guide covers the calculation from vial mass to final volume.
Sourcing both together means the reconstitution medium is on hand the moment a lyophilized vial arrives, and both are covered by the same shipping and traceability record, which keeps a bench workflow tidy and auditable.
