A thread drawing two consecutive days of sustained community attention surfaces a question that researchers acknowledge may have no clean answer: how confident can any self-experimenter be that a peptide sample is free of trace contaminants when independent analytical verification remains largely out of reach.

Bottom line is we probably will never achieve a 100% confidence level in this realm. I certainly never felt totally at ease with my compounded tirz knowing there’s no FDA guarantees with those fine institutions.

§ I.6 · Bad batches

Bad batches just discovered

Last 7 days · classifier-flagged endotoxin or ≤-25% underdose

No bad batches in the last 7 days — that's a good sign.
