How much bac water should I add to a 10mg retatrutide vial?

A common reconstitution is 2ml of bacteriostatic water to a 10mg vial, giving a concentration of 5,000 mcg/ml. This makes dosing simple — for example, 500 mcg equals 10 units on a U-100 syringe. You can use any volume between 1ml and 3ml depending on your preferred concentration.

What syringe size should I use for retatrutide injections?

Most researchers use a 0.5ml or 1.0ml U-100 insulin syringe. A 0.5ml syringe (50 units) offers finer precision for smaller doses (under 1mg), while a 1.0ml syringe (100 units) is better for larger doses. Our calculator supports 0.3ml, 0.5ml, and 1.0ml syringes.

What is the typical retatrutide dosage protocol?

Research protocols typically start at 250-500 mcg per week and titrate up gradually. Common weekly doses in clinical trials ranged from 0.5mg to 12mg. Always follow your specific research protocol and consult published literature for dosing schedules.

Can I use this calculator for other peptides?

Yes. While optimized for retatrutide, this dosage calculator works with any lyophilized peptide. Simply enter the peptide amount in mg, your bacteriostatic water volume, and your desired dose — the math is universal for all reconstituted peptides.
