Understand your prepared solution
Understanding peptide weight and pen units
Peptide weight is measured in mg or mcg: 1 mg = 1,000 mcg. Your vial’s label states how much peptide it contains.
Once dissolved, the final solution volume determines the concentration—how much peptide is in each mL. More liquid means a lower concentration; less liquid means a higher concentration.
For your supplier-confirmed Everform pen, 1 unit = 1 click = 0.01 mL. The peptide weight delivered per click depends on that concentration.
Five pen units always deliver 0.05 mL on this pen, but the peptide weight in that volume can vary.
The calculators below connect these measurements using your inputs; they do not recommend a dose. Choose the syringe or pen tool.
Lyophilised vial preparation for a syringe
Enter the vial amount and BAC water added. Then select your syringe scale to see the amount represented by each marked interval.
Lyophilised vial preparation for an injection pen
Your supplied pen holds up to 3 mL and dispenses 0.01 mL for each dialled unit or click.
Reconstitution means dissolving freeze-dried material in a suitable liquid. Use BAC water only when specified as suitable for the material. These tools use the water added as an estimate of final solution volume unless a measured volume is entered.
Transferring the same solution to a pen does not change its concentration if no extra liquid is added. The pen’s 3 mL capacity is not automatically your solution volume.
Illustrative laboratory arithmetic, not preparation, injection or dose recommendations. Figures assume the stated compound mass and volume. Total blend mass gives a combined amount, not the amount of each ingredient. Pen figures use your supplier-confirmed specification; syringe figures apply only to a U-100 scale.What do these measurements mean?
| Term | Meaning | Useful conversion |
|---|---|---|
| mcg | Microgram: a unit of compound mass, not liquid volume. | 1,000 mcg = 1 mg |
| mg | Milligram: the amount of compound in the vial or measured sample. | 1 mg = 1,000 mcg |
| mL | Millilitre: a measure of liquid volume, not compound mass. | 1 mL = 1,000 microlitres (µL) |
| U-100 | An insulin scale designed for insulin containing 100 insulin units per mL. Here its markings are used only to express liquid volume; they do not measure peptide potency. | 100 marked units = 1 mL 1 marked unit = 0.01 mL |
Mass and volume are different. There is no fixed conversion from mg or mcg to mL without knowing the solution concentration.
For your supplied Everform pen: the supplier confirms 1 dialled unit = 1 click = 0.01 mL. This is specific to this pen and should not be assumed for other pens.
