How to reconstitute PT-141

TR8CE uses one simple standard: 0.1 mL of bacteriostatic water per mg. A 10 mg vial takes 1 mL of water for a clean 10 mg/mL solution. Larger vials scale the water up to fit the glass.

Units are shown for a U-100 insulin syringe. A common starting dose is 1.75 mg. At 10 mg/mL, that draws to 17.5 units on a U-100 insulin syringe.

How PT-141 works

Activates MC-3 and MC-4 receptors in the brain to modulate sexual arousal through central neural pathways rather than the vascular system.
