## About

Peptide Critic provides independent vendor reviews, third-party lab testing and price comparison for research peptides such as BPC-157, GHK-Cu and TB-500. Find compounds by name or synonym, compare vendor ratings and review counts, inspect vendor-level lab-verified COA and warning flags, compare list and discounted prices per milligram, and find coupon codes. Filter comparisons by vendors' shipping origin and pack size, or look up a vendor profile. Results use Peptide Critic's Best Value ranking, which favors partners when offers are comparable; returned buy links are tracked affiliate links. The app returns public catalogue data without sign-in and does not place orders or process payments. Prescription-drug analogues are excluded from compound search and comparison. Research use only; no dosing or medical advice.

## How to use

1. **Add it in ChatGPT** Open Peptide Critic in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Peptide Critic, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Example prompts
