Peptide math,
without the guesswork.
Millions of people are doing mg-to-units conversions on the back of an envelope, for compounds that aren't even approved yet. The FDA has documented hospitalizations from exactly those conversion errors. We built the instrument that makes the math explicit - and the evidence library around it.
- We never sell peptides
- Primary sources cited
- Medically reviewed

The evidence library
What the trials actually measured, what regulators actually said, and where the law actually stands - separated from what sellers claim.
Updated monthly
Retatrutide FDA approval status
Where Lilly's triple agonist actually is in the pipeline, what the TRIUMPH trials showed, and why nothing sold online today is the real thing.
Foundations
How peptide reconstitution works
Concentration, diluent volume, and why the same dose can be 4 units on one vial and 40 on another.
Regulation
Are peptides legal in the US?
The FDA's compounding categories, the 2026 policy signals, and what “research use only” actually means.
Why trust a peptide site?
Don't. Check our sources.
Nearly every peptide site is run by someone selling peptides. We aren't. Every factual claim links to a primary source - peer-reviewed trials, FDA statements, court records. Where evidence is thin (and in this field, it often is), we say so in the first paragraph, not the last.
- 01 - No sales, no vendor sponsorships
