Your peptide arrives as a small amount of white freeze-dried powder at the bottom of the vial. You add bacteriostatic water to it, and it dissolves into a clear liquid you can draw and inject. Here's exactly how.
Let everything reach room temperature
Take the peptide vial and the bacteriostatic water out of the fridge and let them sit for 20–30 minutes. Cold liquid hitting cold powder can shock the peptide.
Decide how much water to add
This sets your concentration. More water = more dilute = more units per dose (easier to measure small doses). Use our calculator below to pick the right amount.
Swab both stoppers
Wipe the rubber top of both the peptide vial and the bac water vial with an alcohol swab. Let it air-dry for a few seconds.
Draw the bacteriostatic water
Draw your chosen volume of bac water into the syringe.
Add it slowly, down the side
Insert the needle into the peptide vial and push the water out slowly, aiming at the glass wall — not straight onto the powder. Spraying directly onto the powder can damage the peptide.
Swirl gently — don't shake
Roll the vial gently between your fingers until the powder fully dissolves. Never shake it. The liquid should turn completely clear. If it's cloudy or has floaty bits, something's wrong — message us.
Refrigerate
Put the reconstituted vial in the fridge. Label it with the date. It's now ready to use.
The calculator
Pick your peptide, vial size, and how much water you added, and our free tool gives you the concentration, the units to draw on a U-100 syringe, and how many doses you'll get per vial.
The calculator's "target dose" options reflect commonly-cited research dose ranges from the published literature. They are not a prescription. What dose is right for you is a decision for you and your doctor — we just do the math.
