Question 1

What is peptide reconstitution?

Accepted Answer

Peptide reconstitution is the process of dissolving a lyophilized (freeze-dried) peptide powder into a liquid solution, typically bacteriostatic water (BAC water). This creates a solution at a known concentration, allowing precise dosing for research protocols.

Question 2

How much BAC water do I add to a peptide vial?

Accepted Answer

The amount of BAC water depends on the peptide amount in the vial and the concentration you want to achieve. Common volumes are 1–3 mL. For example, adding 2 mL of BAC water to a 10 mg vial yields a concentration of 5 mg/mL. Use a reconstitution calculator to determine the exact volume for your desired dose.

Question 3

How do I calculate syringe units for a peptide dose?

Accepted Answer

First, calculate the concentration by dividing the peptide amount (mg) by the BAC water volume (mL). Then divide your desired dose (mg) by the concentration to get the draw volume in mL. Finally, multiply the draw volume by 100 to convert to units on a standard U-100 insulin syringe (where 1 mL equals 100 units).

Question 4

What is a U-100 insulin syringe?

Accepted Answer

A U-100 insulin syringe is a standard syringe calibrated so that 1 mL equals 100 units. It is the most common syringe type used in peptide research for precise sub-milliliter measurements. When researchers refer to 'units' in peptide dosing, they typically mean markings on a U-100 syringe.

Question 5

How many doses are in a 10mg peptide vial?

Accepted Answer

The number of doses depends on the dose size. For example, a 10 mg vial dosed at 250 mcg (0.25 mg) yields 40 doses. A 10 mg vial dosed at 500 mcg (0.5 mg) yields 20 doses. Use a reconstitution calculator to determine the exact number for your protocol.
