Pre-dose checks
Peptide tools
Each tool here answers one question you have before the first injection. Reconstitution math runs against your own vial. The U-100 units calculator translates a dose into the barrel line you pull to. The COA literacy checklist tells you what the certificate is and is not proving when a vendor sends it with the order. For a full cycle plan with schedule, supplies, and stop rules, the protocol checker takes you from goal and source lane to a generated plan.
Reconstitution calculator
Vial mass + BAC water → mg/mL concentration, U-100 draw units per dose, and doses you actually get from the vial.
Use when: You are about to mix a fresh vial and need the math from your own vial, not a number copied off a forum.
U-100 syringe calculator
Dose in mcg or mg + your vial concentration → the exact units to draw on the U-100 barrel for tonight’s injection.
Use when: The vial is already mixed and you need to translate "0.25 mg" or "250 mcg" into the line on the barrel.
COA literacy checklist
What fields a Certificate of Analysis must carry, what each field does and does not prove, and how to spot a doctored or generic COA.
Use when: A vendor sent you a COA with the order and you want to read it as evidence rather than reassurance.
When you need more than one of these
A single tool answers a single question. If you are choosing a primary goal, a cycle length, a source lane, and how the compounds layer together, the planner is the right starting surface; it carries the same math and adds schedule, supplies, stop rules, and risk flags.
