Areas first, compounds second
The catalogue can be read two ways. Product-first: find a compound, read its page, check its certificate. Or area-first: start from a research question, see which compounds the literature attaches to it, and work inward. This page serves the second route.
Each area page follows the same contract: what the field actually studies, what the evidence honestly supports, which compounds we stock for it, and what to read next. Where a literature is thin, the page says thin — the sleep area is four sentences of candour for a reason.
Areas overlap, deliberately. NAD+ appears under energy and features in the knowledge base as not being a peptide at all; the GLP-1 class anchors weight but reaches into metabolic work broadly. The links between pages are the map; every page connects to its neighbours.

One line of honest summary each. The pages carry the rest.
Weight research
The incretin class: one receptor family, three generations of compounds, and the deepest trial data on this site.
Read MuscleMuscle and performance
Growth hormone secretagogues and the pulsatility argument — plus the heaviest anti-doping overlap in the catalogue.
Read RecoveryRecovery and repair
BPC-157, TB-500 and the injury-model literature: substantial in animals, absent in humans, stated as such.
Read SkinSkin research
GHK-Cu and the dermal work — the corner of the field with the most direct line to established cosmetic science.
Read CognitionCognition research
Semax, selank and dihexa: compounds from research traditions the Western literature is still catching up with.
Read EnergyEnergy and longevity
NAD+, MOTS-c, SS-31 and epitalon — mitochondria, ageing claims, and the widest gap between hype and data.
Read SleepSleep research
The smallest area, essentially DSIP and honesty about a literature that never grew.
Read LibidoLibido research
PT-141 and oxytocin: central mechanisms rather than vascular ones, and one genuinely approved molecule.
ReadPages that serve every area
Whatever the research question, these four apply.
