AOD-9604 vs DS5
Side-by-side comparison of key properties, dosing, and research.
- Summary
- AOD-9604 is a modified fragment of human growth hormone (residues 177-191) with an additional tyrosine residue that significantly enhances bioavailability. Originally developed as an anti-obesity drug by Metabolic Pharmaceuticals, it stimulates lipolysis and inhibits lipogenesis without the diabetogenic effects of full GH.
- 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.
- Half-Life
- 30-45 minutes injectable; longer with nasal spray formulation
- Estimated 30-60 minutes (peptide degradation)
- Admin Route
- SubQ, Intranasal, Oral
- Subcutaneous, Intranasal (research)

- Explored for insomnia, chronic stress, and PTSD-related sleep disturbance
- Side Effects
- Localized injection site reactions
- Headache (rare)
- Hypoglycemia risk in combination with insulin (very rare)
- Generally well-tolerated in research subjects
- Possible morning grogginess at higher doses
