Peptide Mixing Kit

The Peptide Mixing Kit provides the consumables needed for reconstituting and handling research peptides -- typically bacteriostatic water, insulin syringes, alcohol swabs, and storage vials in a single package. The bundled format solves the practical problem that these items are sold in larger quantities than a researcher typically needs, and sourcing them from multiple suppliers means dealing with shipping timelines that may not align with compound delivery.

Contents and Use

Bacteriostatic water (0.9% benzyl alcohol) is the reconstitution medium of choice for any peptide that will be stored after reconstitution. The benzyl alcohol is bacteriostatic at this concentration -- it does not kill existing contamination, but it prevents the growth of bacteria introduced during vial puncture, extending usable life to 28-30 days at refrigerator temperature. For single-use reconstitution where the entire vial will be used immediately, sterile water is acceptable; for multi-dose research protocols, bacteriostatic water is standard.

The syringe gauge matters more than researchers sometimes appreciate. 29G or finer needles draw liquid slowly but leave a clean septum hole that re-seals well. Coarser needles (25G and above) core the rubber septum over time, introducing particulates. For low-viscosity peptide solutions, 29G is a good balance of flow rate and septum NAD+ and sirtuin-pathway activity in cited studies. Very viscous solutions (some long-acting fatty-acid conjugated peptides) may require 27G but this is the exception.

Storage

Store bacteriostatic water at room temperature or 4°C, away from direct sunlight. Once opened, label the vial with the date and keep refrigerated; discard after 28 days regardless of remaining volume. Syringes and swabs store at room temperature in their original packaging. Use within the expiry dates printed on all components.
