Posting rules, in plain words
Self-promotion is judged case by case.
- Report Your Affiliations: If you're discussing your own site or otherwise promoting a service/product of yours or anyone else's, you need to gain permission from the Mod Team.
- No Source Solicitation or Price Discussion: This subreddit is for discussing general information and experiences related to peptide research (no human use discussion), and scientific research on peptides. Do not post URLs or vendor names, ask for sources openly or via DM, and do not solicit others to DM you about sources. That is transactional and it is against Reddit rules.
- No Human Use Discussions!: Peptide source is only for discussing peptide research. Please refrain from discussing any personal use of peptides or their effects on humans unless citing actual research.
- Keep It Science/Evidence Based: This is a science/evidence based sub. Usage of citations to support your claims is highly encouraged and may become mandatory.
Quoted from the community’s own published rules. Always re-read them before posting.
