The Complete System

Three pillars. One optimized cognitive architecture.

Peak cognitive performance isn't the result of a single ingredient — it's the product of a system working in rhythm with your body's natural cycles. Core, A.M. Formula, and P.M. Formula are engineered to work together across a full 24-hour window, each addressing a distinct phase of neural performance: build, activate, and restore. 


Pillar 1: The Foundation — Core

Provides the raw materials to support neural foundation.

Core is the structural foundation of the system. By delivering a high-potency, standardized dose of Erinacine A from ErinaPrime™ — a pure Lion's Mane mycelium ingredient produced by Grape King Bio — Core supports the body's natural neurological signaling pathways and the maintenance of healthy neural structure. This is the daily infrastructure your focus, memory, and long-term cognitive resilience are built on. 

  • Cognitive Resilience
  • Brain Health Support

Pillar 2: The Ignition — A.M. Formula

Delivers the daily spark to activate focused cognition.

By combining a clinically-studied dose of Cognizin® Citicoline (500mg), enXtra® (300mg), and Suntheanine® (200mg), A.M. Formula supports the neurotransmitter production, sustained mental energy, and calm attention required for peak daytime performance. Where Core builds the foundation, A.M. Formula switches it on. 

  • Sharp Focus
  • Cognitive Agility

Pillar 3: The Recovery — P.M. Formula

Restores the nightly reset to deepen rest and repair.

By combining a clinically-studied dose of OPITAC™ Glutathione (250mg), PharmaGABA® (200mg, delivering 160mg GABA), and Suntheanine® (200mg), P.M. Formula supports the body's natural overnight restoration and the mind's return to a calm, refreshed state — the restorative processes that occur during sleep, so you wake up ready to perform again tomorrow. 

  • Restorative Rest
  • Overnight Renewal

How the System Works Together

  • Build (Core): Lays down the neural foundation by supporting the body's natural neurological signaling pathways and long-term brain resilience — the structural base that daily performance is built upon.
  • Activate (A.M. Formula): Ignites that foundation each morning with the neurotransmitter precursors, sustained energy, and calm focus needed to convert potential into performance.
  • Restore (P.M. Formula): Closes the loop each evening by supporting the body's natural restorative processes, relaxation, and the transition into restful sleep — ensuring the system resets and compounds gains over time.

Why It's an Optimized System

Each formula is intentionally engineered to complement the others rather than overlap. Core works on the structural timescale (weeks to months), A.M. Formula on the performance timescale (hours), and P.M. Formula on the recovery timescale (overnight). Together, they cover the full arc of cognitive performance — foundation, ignition, and recovery — so no phase of your day is left unsupported. 

How to Use the Stack

  • Morning: Take Core + A.M. Formula together with breakfast to build the foundation and activate focused cognition for the day ahead.
  • Evening: Take P.M. Formula 30–60 minutes before bed to support restorative rest and overnight renewal.
  • Consistency: The system is designed for daily use — benefits compound with consistent daily support of the build, activate, and restore cycle.

I had been searching for a better way to have quite a few of the the ingredients without taking 7 different supplements, or eating a bunch of mushrooms every day. I noticed the difference within an hour of trying the AM formula. I would highly recommend giving this a shot.
