How library entries are researched, graded, and kept separate from the commercial side of the site.

What this site is
TRAINNORTH:LABS publishes a personal healthspan record and a reference library of laboratory research compounds. Neither is medical advice, a dosing protocol, or an endorsement to use any compound on a human being. The library exists so a reader can see what the evidence for a compound actually says, rather than take a seller's word for it.
How an entry gets written
Each library entry starts from the compound's published evidence position: is it an approved medicine anywhere, does it have completed human trial data, is human evidence limited or anecdotal, or is the evidence preclinical (animal or mechanistic only). That position sets the entry's evidence tier before anything else is written. See how grading works for the detail.
A compound's popularity, price, or how often it is discussed elsewhere plays no part in its grade.
Independence from the commercial side
The site links to an independent supplier of research materials and discloses a referral relationship in full at commercial disclosure. That relationship does not change an entry's evidence tier: a compound with completed human trials is not moved up for being easier to sell, and a compound with no human data is not moved down for being harder to. The two are written and reviewed separately.
Corrections
Grading errors get fixed when they are found or reported. See the corrections policy for how to flag one.
