Getting started
- How to reconstitute peptides — adding bacteriostatic water, the common mistakes, and the dosing math.
- Bacteriostatic water: how much to use — what it is, how much to add, and how the amount changes the calculated dose.
- First time using peptides — supplies, choosing a first peptide, and the first injection.
Measuring and injecting
- Insulin syringe units explained — U-100 barrel sizes, reading marks, and converting units to mL, mg, or mcg.
- Injection sites and rotation — the subcutaneous sites, the rotation rule, and avoiding lumps.
Storing and verifying
- Storage and shelf life — fridge vs freezer, lyophilized vs reconstituted, and what ruins a vial.
- Peptide half-lives and dosing cadence — what half-life means for dosing frequency.
- Reading a Certificate of Analysis — HPLC purity, mass-spec identity, and the red flags of a fake report.
