TB 500 - Recover Smarter, Train Harder

Reconstitution & Storage

Mixing a peptide takes about a minute. What people usually get wrong is what happens afterwards. Work through the steps in the guide above, then store the vial the way we lay out further down.

How to Reconstitute

The five steps above cover it. Let the vial and the bacteriostatic water sit out until they reach room temperature. Then run the bacteriostatic water down the inside wall of the vial, slowly, so it does not foam up. Swirl it gently until the powder is gone. Do not shake the vial, and do not squirt the bacteriostatic water straight onto the powder.

How to Store the Mixed Peptide

As soon as it is mixed, put the vial back in the fridge. 2 to 8°C (35.6°F to 46.4°F) is what you want, and it stays there until you have used it up. Write the mixing date on the label. Do not rely on memory for that.

• Temperature: an ordinary fridge, 2 to 8°C (35.6°F to 46.4°F). Not the freezer, not a kitchen cupboard.
• How long it lasts: around 4 weeks. Anything past 28 days goes in the bin.
• Light: keep it in the box or in a dark drawer. Light breaks peptides down.
• Handling: wipe the stopper with an alcohol swab before each draw, use a new needle and do not shake it. Swirl if it needs a mix.
• Freezing: never freeze a mixed solution. Ice crystals form, and a freeze and thaw cycle costs you potency.
• Throw it out if: the liquid goes cloudy, changes colour, or you can see particles in it.

The dry powder is much easier to keep. Store it dry and away from light, at room temperature if it is only for a short while, or at -20°C for the long term. Only mix what you are going to use.
