14 compounds. Mechanisms. Half-lives. The literature, hyperlinked. No dosing guidance, no testimonials — just the science you can verify yourself.
Every Sunday at 9am ET. 5–7 minute read. Five sections: The Compound of the Week, The Stack, The Literature, Lab Notes, The Source.
Written for the founder-biohacker who's already in the game — not a beginner's guide and not a clinic funnel. Signal density beats word count.
Five tests — COA, Half-Life, Literature, Founder-Voice, Conflict. Run them on every compound, every vendor, every newsletter. Including this one.
A reproducible vendor-vetting checklist — date, lab, identity, purity, contaminants. Ninety seconds. Pass or reject.
The 30-minute mental model for split-dosing, AUC, and why a 4-hour-half-life peptide on a once-a-day schedule is a protocol written for the writer's calendar, not the molecule.
I'm Colby. I run heroxbio.com (an RUO peptide vendor, disclosed in every issue's footer) and have spent the last several years buying, researching, and stacking peptides — pre-labs, post-labs, blinded daily journals, the lot.
The Compound is what I wish existed when I started: the Sunday briefing that consolidates the field for serious operators — without the Discord noise, the clinic upsell, or the influencer-grade dose recommendations. The same five-test framework I use on every protocol I run on myself, applied to one compound or stack at a time, every Sunday.
