PT-141 questions
Answers are arithmetic only. Vialwise does not give dosing advice.
How much bacteriostatic water do I add to 10 mg of PT-141?
There’s no single correct amount. The water only sets the strength: more water means less PT-141 in each unit, which makes small doses easier to measure. With a 10 mg vial, 1 mL gives 10 mg/mL, 2 mL gives 5 mg/mL and 3 mL gives 3.33 mg/mL. Make sure the amount fits in your vial.
How much PT-141 is in 10 units?
10 units on a U-100 insulin syringe is 0.1 mL. With 10 mg mixed in 2 mL, 10 units holds 500 mcg. Mixed in 3 mL, it holds 333.3 mcg.
How many clicks is that on a peptide pen?
On a standard peptide pen one click is 0.01 mL, the same as one unit on an insulin syringe. With 10 mg in 3 mL, each click holds 33.33 mcg. A 3 mL cartridge holds 300 clicks.
Which syringe should I use?
Pick the smallest insulin syringe your dose fits in. A 0.3 mL syringe holds 30 units, 0.5 mL holds 50 and 1 mL holds 100, usually marked every 2 units. Smaller barrels spread the marks out, so small doses are easier to read.
