AICAR vs DS5
Side-by-side comparison of key properties, dosing, and research.
- Summary
- AICAR is a cell-permeable AMP analog that activates AMPK (AMP-activated protein kinase) — the master metabolic switch that triggers fat burning, mitochondrial biogenesis, and adaptations normally only achieved through exercise. It has been called the 'exercise in a pill' compound.
- DS5 is a synthetic variant of the delta sleep-inducing peptide (DSIP), a nonapeptide originally isolated from rabbit cerebrospinal fluid during slow-wave sleep. Like DSIP, DS5 is explored for sleep optimization, stress modulation, and circadian rhythm normalization, with proposed improvements in potency or stability over the parent molecule.

- Key Benefits
- AMPK activation mimics aerobic exercise adaptations
- Increased fat oxidation and endurance
- Mitochondrial biogenesis (PGC-1alpha)
- Improved insulin sensitivity and glucose metabolism
- Anti-inflammatory effects
- Potential cardiac protection during ischemia
- Synergistic with actual exercise training
- Reduces hepatic glucose production
- Promotes delta-wave (deep) sleep and improves sleep quality
- May reduce sleep onset latency
- HPA axis modulation for stress reduction
- Non-addictive sleep support without tolerance development
- Potential circadian rhythm normalization
- Explored for insomnia, chronic stress, and PTSD-related sleep disturbance
- Side Effects

- Lactic acidosis at high doses (animal data)
- Injection site irritation
- Generally well-tolerated in research subjects
- Possible morning grogginess at higher doses
- Mild blood pressure fluctuations reported with DSIP
