All research peptides come as a powder because they're freeze-dried. Scientists do this so the peptides stay fresh longer and don't get damaged during shipping. To use them, you'll need to mix the powder with a special liquid called a solvent (like the one we sell on our website).
Bacteriostatic water is a commonly used solvent for reconstitution as it helps maintain peptide integrity and inhibits bacterial growth.
As of this writing, most peptide vials have a capacity of 3mL. NAD+ is 10mL. 5-Amino-1MQ is 5mL.
Typically, 1-2mL of bacteriostatic water is sufficient for reconstitution but consult specific product guidelines for exact volumes. For example, 2mL is usually ideal for products like AOD-9604, while blends such as GHK-Cu, BPC-157, and TB-500 remain within the 3mL vial capacity recommendation.
Vigorous shaking traps bubbles and can induce aggregation resulting in gelling or cloudy results. Reconstitute by letting the solvent run slowly down the vial wall, then gentle swirl/roll. Avoid foaming.
Sodium chloride can precipitate certain peptides. If you used 0.9% NaCl or BAC + NaCl, switch to sterile water for injection or low‑ionic‑strength diluent.
Few sequences don’t dissolve well in plain bacteriostatic water. If still cloudy, a small amount of acidified water (e.g., 0.1% acetic acid) can help.
Very cold diluent can slow dissolution. Bring both vial and diluent to room temperature before reconstitution.
You can use this peptide calculator to help figure out exactly how much solvent you need. Always avoid exceeding the vial's capacity to prevent overflow and ensure accurate measurements.
