More signal stops meaning more effect — a peptide doctor's own teaching example.
The concept
Every peptide acts on receptors, and receptors adapt. Dr. Ashley Froese’s teaching example is epitalon: it “might knock you out for 3 days in a row with good sleep, and then all of a sudden you’re up at 3:00 a.m. again, and again, and again” — which she attributes to probable receptor desensitization.
Why stackers should care
Froese applies the same question to the Wolverine stack: both components drive angiogenesis from different entry points. “If you overdo it, are you saturating receptors and suppressing feedback? Nobody really knows.” That unknown is the honest state of the science for every multi-peptide combination: no combination has been through a human trial, so no desensitization curve for any stack has ever been measured.
The site’s line
Any creator who presents stacking as simple addition — effect A + effect B = both effects — is skipping the receptor problem. Pages in our Stacks section carry the desensitization question by default.
