Generic nootropics are designed for nobody in particular. These are designed for a specific goal, with specific compounds, at specific doses — by the same biochemist who builds full protocols for our private clients. A 30-question assessment maps your neurochemistry and tells you exactly which stack to start with.
Beginner stacks from $49. Advanced tier unlocked by quiz. All three for $249.
Most nootropic companies start with a formula and find customers for it. We started with a biochemist who builds custom protocols for high-performers — and asked him to distill the patterns he sees into three precision stacks, each targeting a specific cognitive system.
Every compound is chosen for a reason. Every dose is based on clinical evidence. Every stack is designed around a specific biological goal — not a marketing category. You get the exact compounds, the exact doses, the research behind each one, and a sourcing guide so you can build it yourself.
This isn't a supplement brand. It's a window into how a biochemist actually thinks about your neurochemistry — packaged in a way you can act on immediately.
What You Get
Each stack comes with everything you need to understand what you're taking, why it works, and how to source it.
Every compound, every dose, and the specific biochemical rationale behind it. Not marketing claims — mechanisms of action.
A clear explanation of which systems the stack targets, how the compounds interact, and why this combination produces the effect.
Direct links to the specific products and brands we recommend. No affiliate games — just the same sources our biochemist uses with private clients.
A clean reference document with the full formulation, dosing schedule, and notes. Take it to your practitioner, your cabinet, or your cart.
The same person who builds full protocols for clients paying 10x–50x more designed these stacks. Same rigor. Same depth.
Log in anytime to review your stack. If we update the science or swap a compound, your portal reflects it automatically.
Three Stacks
Each stack targets a specific cognitive system. Two tiers per stack — beginner compounds you can source today, and an advanced tier unlocked by the assessment for people ready to go deeper.
Prefrontal ACh · mitochondrial energetics · zinc-NMDA gating
Sustained, unbroken cognitive output — by design.
Synaptogenesis · BDNF/NGF cascade · LTP facilitation
Information that consolidates — and stays.
DMN modulation · AMPA flexibility · cognitive rigidity reduction
Ideas from directions you didn't know existed.
Not sure which stack? Let the quiz decide.
30 questions. Maps your cognitive profile across focus, memory, and creative flow. You get a personalized recommendation — and access to the advanced tier if your profile warrants it.

These stacks were designed by Pedro Do Amaral — the biochemist behind every Protocol by Sonder engagement. The same rigor he applies to full protocol design for clients investing $2,500–$10,000+ went into building these three stacks across two tiers.
Every compound was selected based on mechanism of action, clinical evidence, synergistic interaction with the other compounds, and real-world results across hundreds of client protocols. This isn't guesswork, trending ingredients, or marketing-driven formulation. It's biochemistry applied to specific goals.
If you want the full picture — bloodwork, genetics, neurochemistry, a complete custom protocol — that's what our core protocol design is for. These stacks are the tip of the iceberg.
Beginner stacks use clinically-backed compounds you can source from mainstream retailers today — no grey-market, no cycling protocols, no exotic delivery methods. Advanced stacks include research peptides, racetams, and compounds that require more knowledge, stricter dosing, and sourcing from specialized vendors. The quiz determines which tier matches your experience level and goals.
That’s literally the point. We give you the exact compounds, the exact doses, and the exact products to buy. You source everything yourself using our links. What you’re paying for is the architecture — the formulation design, the biochemical rationale, and the knowledge of which compounds interact and why.
Amazon nootropics are designed for the broadest possible market. These stacks are designed by a biochemist around specific biological systems — with compounds chosen for how they interact with each other, not just how they look on a label. You also get the full rationale, not just a supplement facts panel.
Probably — especially if you assembled your stack from podcasts, Reddit, or trial-and-error. These stacks are designed as integrated systems where every compound supports the others. You’ll likely find that some of what you’re taking is redundant and some critical pieces are missing.
Because most people have overlapping goals. You want focus AND memory. You want creative flow AND the ability to consolidate what you learn. The stacks are designed to be taken independently or combined — and the Complete Toolkit saves you significantly over buying them individually.
A full protocol starts with your bloodwork, genetics, and a deep intake — and results in a completely custom system across nootropics, nutrition, training, sleep, and lifestyle. These stacks are goal-based formulations designed with the same rigor, but without the personalization of individual diagnostics. Think of this as the best generic option, built by someone who usually only does custom.
It maps your cognitive profile across three domains — focus, memory, and creative flow — and scores your responses to determine which stack matches your primary need. It also evaluates whether your experience level and goals warrant the advanced tier. You get a personalized recommendation at the end.
Three stacks. Two tiers. Each one designed by a biochemist who usually charges thousands for this level of specificity. Take the 30-question assessment to find out which one matches your brain — or get all three and build the complete toolkit.
