Step by step
- Reconstitute the vial. Add bacteriostatic water to the powder following the reconstitution steps.
- Work out your units. Use the calculator to turn your vial size, water, and target dose into units on the syringe.
- Inject subcutaneously. Clean a rotation site, pinch, and inject into the fat under the skin.
- Log it. Note the date, dose, and site so you can track your cycle and rotate.
Before you start
- Work with a licensed provider
- Get baseline blood work so you can tell whether it is working
- Buy from a source that provides a Certificate of Analysis
What to have on hand
- The peptide vial and bacteriostatic water
- Insulin syringes and alcohol swabs
- A sharps container and fridge space
Start low and monitor
Begin at the low end of your provider's range, watch how you respond, and retest the relevant marker during the cycle.

FAQ
Subcutaneous injections with a short insulin needle are usually close to painless. Letting the vial reach room temperature and rotating sites helps.
For legal, quality-controlled access the cleanest route is a prescription filled by a licensed compounding pharmacy. Products sold "for research only" are not made for human use.
If the powder does not dissolve, let it sit and swirl gently. If the vial is cloudy, discolored, or you contaminated the stopper, do not use it.
