Commercial disclosure
TRAINNORTH:LABS receives a referral benefit on enquiries sent to its supplier. Here is exactly what that means and does not mean.
Last reviewed 24 Jul 2026
The relationship, stated plainly
TRAINNORTH:LABS does not sell, stock, ship, or take payment for any research material. Enquiries made through this site are sent by the visitor, from their own device, to an independent supplier over WhatsApp or email. TRAINNORTH:LABS receives a referral benefit from that supplier when an enquiry made this way leads to an order.
What that does and does not affect
The referral relationship funds the site. It does not influence the library's evidence grading, which follows the methodology above and is written independently of anything commercial. A compound is not graded up for being profitable to refer, and a compound is not graded down for being hard to sell.
What is not disclosed here
The specific referral mechanism used to reconcile orders with the supplier is not published, for the same reason a shop does not publish its supplier contracts. What is disclosed, in full, is that the relationship exists and that it does not change the evidence a reader is shown.
No payment on this site
No card, bank, or crypto details are ever collected by TRAINNORTH:LABS. Payment, if any, is arranged directly between the visitor and the independent supplier, on terms the supplier sets.
