The category spans everything from your morning coffee to research peptides that modulate neurotrophic factors. Here's what's actually worth knowing about. ## Peptide Nootropics ### Semax - **What it is:** Synthetic analog of ACTH(4-10) - **Route:** Intranasal - **What it's studied for:** BDNF expression, cognitive enhancement, neuroprotection - **Notes:** Originally developed in Russia. The N-Acetyl version (NA-Semax) is considered more potent. Start conservative. ### Selank - **What it is:** Synthetic analog of tuftsin - **Route:** Intranasal - **What it's studied for:** Anxiolytic effects, cognitive function, immune modulation - **Notes:** Often paired with Semax. Generally considered to have a calming effect on cognition rather than stimulating. ### Dihexa - **What it is:** Angiotensin IV analog - **Route:** Typically sublingual or intranasal - **What it's studied for:** Extremely potent neurotrophic activity โ€” orders of magnitude more than BDNF in some studies - **Notes:** Very limited human data. Potent stuff. Not for beginners. ### BPC-157 (Cognitive Angle) - Beyond its healing reputation, some research suggests BPC-157 influences the dopaminergic system and may have neuroprotective properties. ## Non-Peptide Nootropics Worth Knowing - **Lion's Mane Mushroom** โ€” promotes NGF (nerve growth factor). The most studied natural nootropic. - **Creatine** โ€” yes, it works for the brain too. 5g/day. - **Magnesium L-Threonate** โ€” the only form shown to cross the BBB effectively - **Omega-3s (DHA)** โ€” foundational. If you're not taking this, start here before anything fancy. ## Stacking Considerations The classic beginner nootropic peptide stack: 1. **Semax** (intranasal, AM) for focus and BDNF 2. **Selank** (intranasal, PM) for anxiolysis and calm cognition 3. **Lion's Mane** (oral, daily) for NGF support Use our Intranasal Calculator (https://www.bodyhackguide.co/tools/intranasal) to figure out spray dosing. ## Safety Notes - Start ONE compound at a time. You can't troubleshoot a stack. - Keep a log of subjective effects โ€” memory, focus, mood, sleep - Cycle peptide nootropics. Don't run them indefinitely without breaks. - Get bloodwork done periodically. Our Bloodwork section (https://www.bodyhackguide.co/) covers what to track. ## Related Guides ๐Ÿ’‰ getting-started ### How to Reconstitute Peptides: Step-by-Step Guide The complete walkthrough for reconstituting lyophilized peptides with bacteriostatic water โ€” no guesswork needed.
