What it does

Sterile water preserved with 0.9% benzyl alcohol (USP), supplied in a 10 mL multi-dose vial. This is the standard diluent used to reconstitute lyophilized research peptides and to fill refillable insulin / peptide pen cartridges (typically 3 mL). The bacteriostatic preservative keeps the vial usable across multiple draws for up to ~28 days once opened.

Typical research protocol

Reconstitution
Draw with a sterile syringe and inject slowly down the inside wall of the peptide vial. For pen loading, draw the volume your protocol calls for (commonly 1–3 mL) and inject into the peptide vial before transferring to the cartridge.
Dose
Typical mixes: 1 mL for small/potent peptides (MT-II), 2 mL for most research peptides (Reta, Tesa, Ipa, Selank, Semax), 3 mL when filling a full pen cartridge.
Pen units (U-100)
On a U-100 pen, 1 mL = 100 units, 2 mL = 200 units, 3 mL = 300 units of total reconstituted volume.
Frequency
Use at the time of reconstitution or pen refill. Store the opened BAC water vial refrigerated and discard 28 days after first puncture.

Recommended: use a single-use, sterile drawing syringe and needle for reconstitution — available in the accessories section.

For in-vitro research only — not for human or veterinary consumption.
