How to draw it up
Draw to
50.0units= 0.500 ml
U-100 insulin syringe · 100 units (1 ml = 100 units)
This dose is only 50.0 units. A 0,5 ml syringe (50 units) lets you read it more precisely.
Concentration
5.00 mg/ml
How many mg of peptide each ml of water contains after mixing.
Per mark
0.050 mg
How much peptide sits in 1 unit on the syringe.
Doses from one vial
4 doses
Lasts ± 4 days at 1× per day.
Reconstitution, step by step
- 1Let the powder vial and the bacteriostatic water reach room temperature first.
- 2Wipe both rubber stoppers with a fresh alcohol swab.
- 3Draw 2 ml of water and inject it slowly down the glass wall of the vial, don't aim straight at the powder.
- 4Gently swirl the vial until everything is fully dissolved. Don't shake, it foams and can damage the peptide.
- 5Draw your dose up to 50.0 units and store the vial refrigerated (2–8 °C), away from light.
Once reconstituted, most peptides keep for roughly 3–4 weeks refrigerated. Always check the label of the specific product.
For laboratory research only. Not for human or veterinary use. Always reconstitute with sterile bacteriostatic water and store per protocol.
