Opened vials need refrigeration, which makes larger bottles a liability away from base. The 3ml solves that: it stays sealed and stable at room temperature until you need it, then covers one to three reconstitutions at typical volumes of 1 to 3ml per peptide vial. Travel, a short protocol, or a first order to verify our product before committing to a bigger size, this is the format for all three.
It also earns a place in a stocked setup. Keeping a sealed 3ml alongside an open larger bottle means a mid-protocol breakage or a lost vial never stalls your schedule.
The Formula
Sterile water for injection and 0.9% benzyl alcohol, both on the label, nothing else in the vial. The preservative inhibits bacterial growth between draws, which is what permits multiple withdrawals over the 28-day window and what matches the USP bacteriostatic water monograph used in clinical practice.
The same label test applies at this size as any other. Small “reconstitution solution” vials on marketplaces are frequently unpreserved sterile water, single-draw only. No benzyl alcohol listed means no multi-dose protection, whatever the title claims.
Opening and Storage
Sealed: controlled room temperature, out of direct light, good until the printed expiry. Once punctured: refrigerate at 2 to 8C, swab the stopper before every draw, fresh sterile syringe each time, date the vial, 28 days maximum. At this volume most users finish the vial well inside the window, which is the point.
One Direction Only
No sterile product sold here is ever returned, restocked or resold. Your vial goes factory, warehouse, you, sealed throughout. Damaged on arrival? Photo within 5 days of delivery gets a full refund or replacement, usually with no requirement to send anything back.

FAQ
Is 3ml enough to reconstitute one peptide vial?
Yes. Most reconstitutions use 1 to 3ml, so one vial covers at least one full reconstitution and often two or three at lower volumes.
Why not just fly with my opened larger bottle?
Opened vials should stay refrigerated and lose their sterility assurance if mishandled. A sealed 3ml travels at room temperature with no clock running, then opens fresh at your destination.
Can I buy these in multiples?
Yes, and for repeated travel or backup stock, multiples of the 3ml beat opening a large bottle you cannot finish. For regular home-base use, the 10ml or 30ml costs less per ml.
