GHK-Cu plasma levels decline 75% between ages 20 and 80. A deep dive into the copper tripeptide that modulates over 4,000 genes — the Broad Institute finding that stopped Dr. Clarianne cold — and what it means for longevity, post-surgical recovery, skin aging, and hair loss in clinical practice.
30 years of clinical data. Approved in 35 countries. Almost completely unknown to US practitioners. A complete clinical guide to Thymosin Alpha-1 — the immune modulator that upregulates when suppressed and downregulates when overactive.
The 4-question protocol framework that replaces memorized compound lists with a systematic, patient-centered decision process grounded in the PNEI NeuroCode™. The framework nobody teaches — but every practitioner needs.
The FDA's Pharmacy Compounding Advisory Committee is meeting July 23-24 to vote on whether BPC-157, TB-500, and five other compounds belong on the 503A Bulks List. Here is what practitioners need to understand before the vote.
The Protocol Letter is not a summary of headlines. It is not a product newsletter. It is a weekly deep dive into the science of amino acid compounds and holistic health — written by a practitioner, for practitioners.
Each issue covers one topic in depth: the mechanism, the clinical evidence, the PNEI axis context, and the practical implications for practice. No fluff. No speculation. No agenda beyond the science.
"I write the newsletter I wish I had when I started. The one that treats practitioners as scientists — not consumers."
— Dr. Clarianne Jiménez, PhDMechanism, evidence, clinical context — not a summary, a deep dive.
Every compound placed within the 7-axis framework so you understand the system, not just the molecule.
What this means for the patients already in your practice — not theoretical applications.
Every factual claim sourced. You can verify everything. That's the standard.
The PNEI NeuroCode™ Certification is where the full framework lives — 12 weeks, 7 axes, and a complete clinical education in amino acid compounds.
