Buying smart 5 lessons
- Comparing prices: price per mg, kits and vial countsWhy the sticker price misleads, and how to compare listings fairly.
- How to read a certificate of analysis (COA)What each part of a peptide lab report means and what to check before trusting it.
- Purity isn't the same as the right amountWhy a 99% pure vial can still be a bad vial, and how lab-test scores account for it.
- Endotoxins and sterility: what lab reports can missThe contamination tests most peptide COAs don't include, and why they matter.
- Research chemical, compounded or FDA-approved?The three ways peptides are sold in the US, and what each one guarantees.
Working with the numbers 5 lessons
- Units: mg, mcg, mL and IUThe unit mix-ups behind most calculation mistakes.
- Reading a U-100 insulin syringeWhat the 'units' on an insulin syringe measure and how they relate to mL.
- Reconstitution math: water, concentration and unitsHow the amount of water you add sets the strength, with worked numbers.
- Storage and how long a mixed vial lastsPowder vs solution, temperature, and the 28-day rule for opened multi-dose vials.
- What's in a blend vialHow to work out each component's amount when one vial holds several peptides.
Reading the research 3 lessons
- How to judge a study headlineQuestions that separate strong evidence from a promising rat study.
- What the A–D evidence grades meanHow this site grades the research behind each peptide, and what a grade doesn't say.
- Clinical trial phases and registrationsWhat phase 1, 2 and 3 mean, and why a registered trial isn't a result.
