What DSIP does: DSIP (Delta Sleep-Inducing Peptide) is researched for promoting deep restorative sleep, reducing stress, and improving next-day energy and focus — without grogginess or dependence. Ideal for anyone researching sleep quality, stress recovery, or circadian health.
PEPTIVA DSIP 5MG VIAL contains 5mg of high-purity lyophilised DSIP — a naturally-occurring 9-amino acid nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated in 1977. Peer-reviewed studies report DSIP's ability to promote slow-wave (delta) sleep — the deepest, most physically restorative stage — without altering REM sleep or causing morning grogginess. It readily crosses the blood-brain barrier at 849 Da molecular weight and modulates hypothalamic-pituitary-adrenal (HPA) axis activity, reducing basal ACTH and cortisol levels. Additional research explores DSIP's involvement in stress recovery, analgesic effects, mood modulation, and non-habit-forming sleep support.
- Deep sleep — researched to promote slow-wave (delta) restorative sleep
- Stress recovery — reduces cortisol and modulates HPA-axis activity
- Better next-day energy — no morning grogginess reported in studies
- Non-habit forming — no dependence or withdrawal in published research
- Blood-brain barrier permeable — acts directly on brain sleep centres
- Mild analgesic effects — researched for pain-threshold modulation
- Fast-acting nonapeptide — 849 Da, rapid onset
