Amazon has thousands of listings for every supply on this site. PepPrep narrows each one to a few and explains the numbers. Six steps, in order; most people need three of them.
- Work out what you actually need. Which one do I need? asks what you are doing, then lists must-haves, nice-to-haves and things to skip. Three taps.
- Understand the words on the listing. The glossary explains gauge, U-100, luer-lock, bacteriostatic, dead space and the rest in a sentence each. The listings guide shows what a bad Amazon listing looks like.
- Choose the right version. The Product Finder turns specifications into three to five products. Compare puts any of them side by side with the differences marked.
- Do the arithmetic once. The reconstitution calculator answers "how much water, which line". The temperature-loss calculator answers "is it still good after the parcel sat in the sun".
- Read the guide for your situation. The safety checklist first, then mixing, storage, flying or disposal. Every guide says which supplies it assumes.
- Buy through your own country's Amazon. Every button on this site opens the listing in the store for your country (US, Canada, UK, Germany and the EU, Australia), with a backup listing if the first is out of stock. Affiliate links; your price is the same.

What this site is, and is not
PepPrep sells nothing and stocks nothing: it lists Amazon products, and none of them are peptides or medicines: only the supplies and equipment around them. It gives no dosing advice and its tools never ask what you are taking. Where a rule depends on your country (flying with supplies, disposing of needles), the guides link to the official page for each country rather than paraphrasing it.
