Enter your vial size, your dose and how often you take it. You'll get the bacteriostatic water to add, the exact units to draw shown on a real syringe scale, and how long the vial lasts.
Pick one to pre-fill a common vial size, dose and frequency — or choose custom and type your own.
Milligrams of dry peptide in the vial, printed on the label.
How much peptide you take in a single shot.
Sets how long one vial lasts. It doesn't change the units you draw.
How much you mix into the whole vial. This sets your draw size — never the number of doses.
Every insulin syringe uses the same units — 1 unit is 0.01 mL. This only changes the barrel size and how crowded the marks are.
List every peptide sharing the vial and how many milligrams of each. They all dissolve into the same water, so every draw delivers all of them in proportion.
Total millilitres mixed into the vial.
Pick the peptide you dose to. Everything else follows from the ratio in the vial.
How long a vial lasts is vial mg ÷ dose mg. A 10 mg vial at 2 mg a shot is five doses, whether you reconstitute with 1 mL or 5 mL. Adding more water only dilutes what's already there.
Concentration is mg ÷ mL. More water means a weaker solution and more units pulled per dose; less water means fewer units. Aim for a draw that lands on a mark you can read without squinting — roughly 10 to 50 units.
Every insulin syringe is marked so 1 unit = 0.01 mL. U-100, U-50 and U-30 only change the barrel size and how far apart the marks sit. The same volume is the same unit number on all three.
In a shared vial each compound has its own concentration — its own mg divided by the same water. One draw delivers all of them at the ratio you mixed, so you dose to one and read off the rest.
Angle the needle so the water runs down the inside wall rather than jetting onto the powder. Swirl or roll gently, never shake. Leave it to dissolve on its own.
Keep lyophilised vials cool and dark. Once reconstituted, refrigerate at 2–8 °C and keep the stopper wiped with alcohol before every draw.
