Question 1

How do you calculate a dose for a blended peptide vial?

Accepted Answer

Each peptide in the vial has its own concentration equal to its milligrams divided by the shared bacteriostatic water volume in mL. When you draw a volume, every component comes along in that same volume, so pick one component as the anchor, divide its target dose (in mg) by its concentration to get the draw volume, then multiply each component’s concentration by that volume to see how many micrograms of each you actually deliver.

Question 2

Why can’t a normal reconstitution calculator handle a blend?

Accepted Answer

A single-peptide calculator solves for one concentration. In a blend, two to four peptides share one vial and one water volume, so a single draw delivers a fixed ratio of all of them at once. You can only target one component’s dose freely — the others are locked to that same volume, which is exactly what a blend calculator surfaces.

Question 3

How many doses are in a blended vial?

Accepted Answer

Divide the total bacteriostatic water volume in the vial by the volume of a single draw. Because every component is depleted in proportion to the volume withdrawn, that single figure is the doses-per-vial for the whole blend.
