nobody warned me about reflux and I would have liked the warning

Discussionbranch of 5 comments

Posting this because I searched for it and got nothing useful. Setup: 0.5mg, week 95, injection-site soreness present but not ruining anything. I changed exactly one variable — area percent — and tracked it for 15 weeks. Result: a difference, but a small one, and well inside what I would call noise if someone else…

That is net peptide content, not purity. Different number, different meaning.

About c/coa

How to read a certificate of analysis and what it does and does not tell you. Area% versus mass%, identity versus quantity, water content, related substances, acetate counterions, and the difference between a vendor-supplied COA and an independent test on the vial you actually received.

c/coa rules
  1. Post the full document. Cropped COAs that hide the batch number or date get removed.
  2. Redact your own name and order id, not the vendor's batch details.
  3. No "is this good?" without saying what the compound and claimed purity are.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
