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.

Frequently asked

How much bacteriostatic water do I add to PT-141?

What is a common PT-141 dose?

A common PT-141 starting dose is 1.75 mg, which at 10 mg/mL draws to 17.5 units on a U-100 insulin syringe.

How do you reconstitute PT-141?

Draw bacteriostatic water into a syringe, inject it slowly down the inside glass of the PT-141 vial (not onto the powder), and swirl gently until clear. Store refrigerated and use within the common window.

How do you reconstitute a 10 mg PT-141 vial?

Add 1 mL of bacteriostatic water to a 10 mg PT-141 vial for a 10 mg/mL solution. A 1.75 mg dose then draws to 17.5 units on a U-100 insulin syringe.
