The peptide people reach for when the problem isn’t falling asleep but staying asleep — the 3–4am wake that growth-hormone peptides don’t address.

DSIP (delta sleep-inducing peptide) is a naturally occurring nine-amino-acid peptide first isolated from rabbits in slow-wave sleep in the 1970s. It is studied for its role in sleep maintenance and in modulating the stress axis, rather than for sedation — which is why it is the peptide most often chosen for early-morning waking rather than for difficulty falling asleep.
Where CJC-1295 + Ipamorelin deepen the early-night slow-wave phase, DSIP is aimed at the other half of the night. Many guests run the two together: the GH blend for depth, DSIP for continuity. It is a research peptide, not an approved medicine, offered only after a clinician screen.
Guests typically come to DSIP seeking:
Sealed, COA-verified vial delivered in Tulum. You reconstitute and dose yourself. +$15 delivery, free over $250. A clinician still does a quick screen before we confirm.
Bac water, a month of syringes, reconstitution syringes, prep pads, your personalized dosing page with batch certificates, a taught first dose and WhatsApp support. Kit is +$85 once per order, however many vials. Delivery included.
5 mg + 3 mL bac water = 1.67 mg/mL, so 100 mcg = 6 units on a U-100 syringe.
100 mcg (6 u) subcutaneous ~30 minutes before bed to start; titrate to 150–200 mcg (9–12 u) if needed. Nightly, or 5 nights on / 2 off. One vial is about a 4-week course.
General guidance, not a prescription — your clinician confirms your protocol at screening. Reconstituted vials keep ~4 weeks refrigerated.

Every vial ships with a Certificate of Analysis you can check against the lab’s own database — identity, content and purity by HPLC and mass spectrometry — and your dosing page carries the batch number that matches the label. Buy the vial alone if you know what you’re doing; add the kit if you want a clinician to teach the first dose. These are investigational peptides, not FDA-approved, offered in a wellness context after individual screening.
DSIP (delta sleep-inducing peptide) is a short peptide studied for its role in sleep maintenance and stress modulation. It is a research peptide, not an FDA-approved medicine, and we offer it only after individual clinician screening in a wellness context.
The GH blend supports the deep, slow-wave phase early in the night. DSIP is aimed at staying asleep through the second half. They address different halves of the night, and many guests run both.
5 mg reconstituted with 3 mL bac water gives 1.67 mg/mL, so 100 mcg is 6 units. Start at 100 mcg about 30 minutes before bed and adjust in small steps. The full kit includes a personalized dosing page with your exact units.
Yes. Vials-only is $75 with Tulum delivery ($15, free over $250). The Start & Continue kit adds bac water, syringes, a dosing page and a taught first dose for $85 per order.
