  4. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  5. No contact handles, wallet addresses or tracking numbers — they identify people.
  6. Be recognisably decent. Disagree hard, insult nobody.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
