Dosing Mention Comparison
Dihexa dosing
- host: 10 milligrams per dose; daily use eventually feels drug-like (00:03:31)
- DrJones: Anecdotal reports indicate users exploring Dihexa cycles for potential neurogenesis/synaptogenesis effects (00:13:56)
- Steve: Two or three times per week, taken in the morning due to long-lasting effects; cycle through with bromantane and noopept rather than daily use (00:15:05)
- host: The host reported using 5 mg orally once a day in the morning for a 14-day cycle, followed by 6-8 weeks off. Dihexa is reported to be... (00:18:24)
- Speaker 1: According to Speaker 1's approach: Do not start with Dihexa; first clear neuroinflammation, get mitochondria functioning, optimize... (00:20:19)
Noopept dosing
- host: Users report taking 10 mg (up to 20 mg) orally, 30 to 60 minutes before sparring sessions or matches. Some report starting with lower... (00:09:04)
- Steve: 10 mg twice per day, morning and afternoon (00:15:15)
- Steve: 2-3 servings daily, stacked with alpha-GPC + uridine in final serving (00:55:07)
- Speaker 1: Nasal spray Noopept described as short acting for a couple hours; capsules may affect sleep while nasal spray did not for speaker. (01:39:04)
Side Effect Notes
Anecdotal reports for both compounds vary by route, dose, and individual. Neither should be treated as an approved medication. Consult a qualified clinician.
When To Choose Which
