AICAR Benefits
- ✓Increases endurance capacity, enhances fatty acid oxidation, promotes mitochondrial biogenesis, improves glucose uptake, cardioprotective effects
Desmopressin Benefits
- ✓memory consolidation
- ✓reduced pressor burden
- ✓recall support
- ✓short-term learning
AICAR Dosing
Research doses: 50-150 mg subcutaneously. Typically administered 30-60 minutes before physical activity in research settings.
Desmopressin Dosing
intranasal research dosing|10-40 mcg or IU-equivalent studies|single-dose protocols
AICAR Side Effects
- ⚠Potential hypoglycemia, lactic acidosis at high doses, injection site reactions. Banned by WADA as a metabolic modulator.
Desmopressin Side Effects
- ⚠hyponatremia
- ⚠headache
- ⚠nasal irritation
Research Overview
AICAR
Salk Institute researchers demonstrated AICAR could increase endurance in sedentary mice by 44% without exercise training. Activates AMPK, triggering PGC-1α expression, mitochondrial biogenesis, and enhanced fatty acid β-oxidation.
Desmopressin
The literature is mixed, but desmopressin has shown memory-related effects in selected populations and experimental paradigms. Its cognitive effects are usually discussed as a vasopressin-pathway probe rather than a primary nootropic.
