Frequently Asked Questions
Straight answers to the questions we are asked most.
Last reviewed September 1, 2026
Does Peptide Atlas sell peptides?
No. Peptide Atlas is an independent publication. We do not manufacture, sell, distribute or fulfil any product, and our vendor and supply directories list third-party companies we do not own or control.
Can you tell me what dose to take?
No. We summarise protocols reported in published research and approved labels, and we cite the source. We do not provide individualised dosing, and nothing on this site is medical advice.
Why do so many compounds have a low evidence grade?
Because most peptides discussed in wellness settings have been studied in animals and cells rather than in people. The grade reports that honestly rather than smoothing it over.
Does a low grade mean a compound does not work?
No. It means we do not know. Unproven and disproven are different states, and conflating them is as much an error as overselling.
Are your evidence grades the same as an official system?
No. The A-to-E scale is our own editorial framework, applied consistently across the library and explained on every compound page. It is designed for transparency, not to replace formal appraisal tools.
