The Journal

Quietly considered writing on biology.

Notes on the compounds we carry, the questions we are asked most often, and the slow practice of treating one’s own biology with care.

Coming soon

The reconstitution problem: a practical guide.

Dilution math is the single most common question we receive. We break it down from first principles — no assumptions, no guesswork.

Coming soon

What “research grade” actually means — and what it doesn’t.

The phrase appears on nearly every peptide label in North America. We unpack what it does and does not promise, and why the gap between suppliers matters.

Coming soon

GHK-Cu: the copper peptide literature in plain English.

Decades of research, one of the most well-studied peptides in the catalog. A plain-language summary of what the evidence actually shows.

Coming soon

The GLP-1 landscape: Tirzepatide, Retatrutide, and what comes next.

From dual to triple agonism — a brief account of where the metabolic peptide research space currently stands.

Coming soon

BPC-157 and TB-500: what separates them, and when researchers use both.

Two of the most studied healing peptides, often conflated. A clear explanation of their distinct mechanisms.

Coming soon

NAD+ and the mitochondrial peptides: a longevity reading.

MOTS-c, Epithalon, and the emerging longevity peptide literature — what the animal data shows and where the gaps remain.
