There is no fixed amount: the volume of bacteriostatic water you add sets the concentration. More water means a lower concentration; less means a higher one. A reconstitution calculator gives the exact volume for your target.
It is a concentration choice
The amount of peptide in the vial is fixed. Adding water only changes how concentrated the solution is. For example, a 10 mg vial in 1 mL of water is 10 mg/mL, while the same vial in 2 mL is 5 mg/mL. Both contain the same total peptide.
Choosing a volume
Common choices are round numbers like 1 mL, 2 mL, or 3 mL, picked so the resulting concentration makes measurement convenient on a U-100 syringe. The calculator lets you try volumes and see the resulting concentration and draw amounts instantly.
Use the reconstitution calculator
Enter vial strength and water volume to get concentration, draw units, and doses per vial.
A handling note
Add the water slowly down the vial wall and swirl gently. This is laboratory preparation of a research compound, not guidance for human use.
Key takeaways
- The amount of water sets the concentration, not the peptide amount.
- More water means a lower concentration; less means higher.
- A 10 mg vial is 10 mg/mL in 1 mL, or 5 mg/mL in 2 mL.
- A calculator gives the exact volume for your target.
A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
