The part nobody explains when you start. Here is the clean, no-guesswork process for reconstituting and storing lyophilized research peptides, written for the bench. General handling protocol only, for laboratory research use.
Let the lyophilized vial and your bacteriostatic water sit out until neither is cold. Cold glass and cold liquid cause fogging and clumping.
Alcohol-wipe both rubber stoppers and let them dry. Use a fresh sterile syringe for every draw.
Angle the needle so the bacteriostatic water runs down the inside glass wall, not directly onto the powder. Never inject force straight into the pellet.
Swirl gently. Do not shake. Give it a few minutes to go fully clear. Peptides are fragile and shaking degrades them.
Once reconstituted, keep it refrigerated and out of light. Reconstituted peptides have a shorter shelf life than the lyophilized powder.
Concentration equals total mcg in the vial divided by the mL of water you add. Every compound and vial size is different, which is why the full guide has the per-compound tables.
