Reconstitution explained

Your peptide shows up as a dry powder, which is something you cannot inject. So you reconstitute it, which just means adding liquid to turn it into something you can draw into a syringe. The liquid is bacteriostatic water (bak-teer-ee-oh-STAT-ik), which is water with a tiny bit of preservative so it stays clean in the fridge for weeks. You'll sometimes see this abbreviated as "BAC water."

A standard insulin syringe holds 100 units in 1 mL. This makes the math really simple. 1 unit is 1% of a mL. There are 100 marks on a syringe, so if your dose is 8 units, you're pulling to the 8th mark printed on the syringe.

The amount of water you add to your powder is a choice, not a fixed rule. More water spreads the same peptide across more units, which makes a small dose easier to measure accurately. Less water packs it into fewer units. You are deciding how spread out each dose is.
