c/hplc rules

Chromatogram or it did not happen. Axis labels included.
State the method: column, gradient, detection wavelength, injection volume.
Area% is not mass%. Posts that conflate them get a correction flair, not a removal.
Independent community. Nobody here sells anything, and anyone who tries is banned.
Not medical advice. Describe what you did; never prescribe to a stranger.
Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
No contact handles, wallet addresses or tracking numbers — they identify people.
Be recognisably decent. Disagree hard, insult nobody.
