← All stacks🧠 Focus & Mood
Limitless+
Sharp, calm, and driven — rewire your brain for focus without the Adderall crash or the jitter.
Why this stack works
Brain fog, no focus, mentally flat — most people reach for Adderall or more caffeine, which just dump dopamine and leave you fried. The real fix isn't more gas in a broken engine — it's building a better engine. This stack rewires your brain for focus and keeps you calm, without the crash.
The 3 — and what each does
The 'real-life Limitless' peptide — raises BDNF to sharpen focus, memory, and verbal fluency, with none of the stimulant jitter.
Takes the anxious edge off without sedation or dependence — so you're clear and calm, not wired.
The coenzyme your mitochondria run on. Refill the tank and ~500 cellular reactions switch back on — real, all-day energy, and it kills the MOTS-c startup fatigue.
How they work together
Semax raises BDNF to sharpen focus, memory, and verbal fluency — the 'real-life Limitless' effect — while Selank takes the anxious edge off so you're clear, not wired. NAD+ underneath gives your brain the cellular energy to actually run at that level. Sharp, calm, and driven, with none of the stimulant burnout.

⚡ Support the stack — run it right
🧠 Semax: Focus stack: L-tyrosine + Mg + L-theanine + NAD+; pair Selank for the cortisol edge.
🌊 Selank: Pairs with Semax; add L-theanine + glycine + Mg for the wind-down.
⚡ NAD+: Pairs with MOTS-c to kill the startup fatigue; SubQ only (oral is destroyed in the gut).
💡 Pro tips — running this stack
▹ Clear division of labor: Semax drives (focus, BDNF up in ~3 hrs), Selank smooths (tapers the cortisol edge Semax can cause), NAD+ powers (the energy to actually process). Complementary, not redundant.
▹ Don't drop Selank to 'save money' — Semax alone can dip HRV and raise cortisol; Selank is the balancer that makes the focus usable.
▹ Effects are same-day (Semax ~3 hrs, Selank ~30–60 min, NAD+ fast) but the real rewiring is cumulative over weeks — it 'builds a better engine,' and the gains persist after you stop.
▹ Keep NAD+ SubQ (oral/NMN is gut-destroyed) — it's the ATP floor the whole nootropic effect sits on; without it Semax has focus but no fuel.
