An extremely powerful brain peptide -- it's millions of times more potent than your brain's own growth signal (BDNF) at helping brain cells form new connections. One of the strongest nootropics available for memory and cognitive enhancement.
What to Expect
Week 1–2
Rapid cognitive enhancement — improved memory formation, focus, and mental clarity. Enhanced pattern recognition. Mood brightening.
Week 3–6
Sustained nootropic effects. Improved spatial and verbal memory. Enhanced learning capacity. Neuroplasticity effects building. BDNF pathway activation.
Week 8+
Peak cognitive benefits. Long-term neuroprotective effects. However, long-term safety data is very limited — caution warranted.
Common Side Effects
Dosing
10-20 mg oral or 5-10 mg subq daily. Cycle for 4-8 weeks with breaks in between.
Practical Guide
Reconstitution
Oral or intranasal formulations available. Subq: dissolve in DMSO or appropriate solvent per research protocols.
Storage
Store in dark, cool place. Protect from light and moisture. Use quickly after preparation.
Timing
Morning or early afternoon. Avoid evening dosing — may interfere with sleep. Start with lowest possible dose.
Food
Sublingual: do not eat or drink for 15 minutes after. Intranasal: clear nose before administration.
