Stock wholesale starts at 252 vials for 10 mL glass (one tray) or 304 vials for 30 mL glass (two trays). For 10,000+ vials, request a custom quote.

In-stock orders ship within 48 hours. Private-label orders typically require 1-3 weeks after artwork approval; the final schedule is confirmed in your quote.

Yes. We can provide a Certificate of Analysis from a recent production lot so your QA team can review before committing. Just reach out via the contact form or email and we will send one over.

Stock glass vials ship in their full trays, which we reuse to protect the vials. Shipping is calculated separately for each order based on the destination and delivery needs.

We currently offer 10 mL and 30 mL vials. Both sizes contain bacteriostatic water formulated with 0.9% benzyl alcohol as a preservative.

Formulated and tested to meet USP-grade standards. Production follows cGMP and USP 797 requirements, documented SOPs, and QC controls. Every lot is independently tested for sterility, endotoxin, pH, and preservative concentration.

It is unbuffered: nothing added but 0.9% benzyl alcohol, typically measuring pH 5-6, within the USP pharmacopeial range (4.5-7.0). Pure water cannot hold pH 7 by itself; left in contact with air it absorbs carbon dioxide and drifts toward 5.6, and holding it neutral would take phosphate or bicarbonate buffer salts that would end up in every solution you reconstitute. Unbuffered water has essentially no buffering capacity, so once you add your peptide, the peptide's own chemistry sets the solution's pH. Benzyl alcohol preserves equally well across this range, so nothing is lost by leaving it unbuffered.
