For in vitro research use only · Not medical advice

Preset to a 10 mg PT-141 (Bremelanotide) vial in 2 mL of diluent. A 10 mg vial in 2 mL gives 5 mg/mL. Keep reconstituted material protected from light.

A 10 mg PT-141 (Bremelanotide) vial reconstituted with 2 mL gives 5 mg/mL. Measuring 0.100 mL gives 500 mcg per portion — about 20 portions from the vial.

Choosing a diluent for PT-141 (Bremelanotide)

Water-soluble and straightforward to reconstitute. The molecule is cyclic — closed through a lactam bridge rather than a disulfide — which makes it conformationally constrained and notably more rigid than a linear peptide of similar length.

PrimaryBacteriostatic water (0.9% benzyl alcohol)
Alternative 1Sterile water (USP grade)

Handling notes for PT-141 (Bremelanotide)

  • Protect from light at all stages.
  • Standard gentle reconstitution; the constrained ring is not agitation-sensitive in the way flexible long chains are.
  • Store refrigerated and aliquot rather than repeatedly sampling one vial.

After reconstitution

StorageRefrigerate at 2–8 °C, protected from light on account of the tryptophan residue.
Working windowCommonly worked with for 2–4 weeks at 2–8 °C.
Freeze–thawAliquot on reconstitution. The lactam ring is chemically robust, so the constraints here are the usual oxidative and interfacial ones.
