DS5- Summary
- Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH) with 100x the potency of native GnRH. An FDA-approved drug (Trelstar) for prostate cancer and precocious puberty, it is also used in post-cycle therapy (PCT) to rapidly restart the hypothalamic-pituitary-gonadal (HPG) axis after anabolic steroid suppression.
- 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
- Depot forms: weeks to months; aqueous: 6-8 hours
- Estimated 30-60 minutes (peptide degradation)
- Admin Route
- SubQ, IM
- Subcutaneous, Intranasal (research)

- Key Benefits
- Rapid HPG axis restart after steroid use
- Single-injection PCT protocol possible
- Massively elevates LH and FSH via flare effect
- Restores endogenous testosterone faster than traditional PCT
- FDA-approved for established medical uses
- 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
- Initial testosterone flare (intended)
- Injection site reactions
- Hot flashes (with chronic use)
- Decreased libido (chronic dosing)
- Generally well-tolerated in research subjects
- Possible morning grogginess at higher doses
- Mild blood pressure fluctuations reported with DSIP
- Limited human safety data for DS5 specifically
