Practical guides for the bench.
How to do the things that matter — calculate doses without dropping a digit, mix vials without compromising sterility, pick an injection site that won’t scar over. New to peptides? Start with the beginner’s guide below.
Start here — the beginner's guide
From a vial of powder to your first dose, in plain language. Step-by-step orientation that takes the fear out of the process and links into the deeper guides where you want more detail.

Peptide dose calculator
Reconstitution dose math with real-time edge-case warnings. Vial mg + BAC water + desired dose → exact draw volume and units on a U-30 / U-50 / U-100 syringe.
OpenReconstitution guide
Step-by-step sterile mixing for the bench. Live math sidebar updates as you change vial parameters; step state and form state persist so you can pause and resume.
OpenPeptides by goal
NewBrowse the library by what you're trying to do — weight, recovery, longevity, sleep, skin. Each entry is honestly labeled research-grounded vs community-practice. Add straight to your stack from the goal section.
OpenStack builder
NewPick the goals that matter. We'll pre-fill peptide candidates with sensible doses and frequencies; adjust inline; one button adds the entire stack. Skip the picker-by-picker grind.
OpenSyringes & needles
Gauge math (the inverse scale), needle lengths, syringe capacity, sterilization symbols on packaging, single-pack vs bulk bag, and the reconstitution-syringe recommendation that protects your vials.
OpenInjection locations & technique
Common subcutaneous sites, rotation patterns, sterile-technique fundamentals, what to expect at the injection site, and when to call your clinician.
OpenStorage & shelf life
What lyophilization is, the temperature range that keeps unreconstituted powders stable, why heat and UV matter, and the 4–6 week post-reconstitution window where peptides lose efficacy (not safety).
OpenNasal sprays
Which peptides are absorbable nasally and which aren't, why molecular size matters, why saline (not BAC water) is the right vehicle, and what the standard 0.1 mL pump actually delivers.
