A few private questions, then you connect to a licensed provider on a live video call — usually within seconds.

DSIP — delta sleep-inducing peptide — is a nonapeptide first described in 1977, isolated from the cerebral venous blood of rabbits during induced slow-wave sleep. It takes its name from that observation.
Despite the name, the human evidence for a sleep effect is limited and inconsistent, and the peptide's mechanism is not well established. DSIP is not an FDA-approved medication and is not approved to treat insomnia or any sleep disorder.
This is a compounded preparation, not an FDA-approved medication, and compounded drugs are not reviewed by the FDA for safety or effectiveness. Individual results are not guaranteed. It is prescribed only where a licensed provider determines it is appropriate after reviewing your health history.
DSIP is discussed almost entirely because of its name and its origin in slow-wave sleep research from the 1970s. The human literature is small and mixed, and no sleep indication has been established.
Every DSIP prescription here follows a live consultation with a licensed provider who sees your health history, current medications and goals. If it isn't appropriate for you, it isn't prescribed.
Your vial is compounded by a licensed U.S. 503A pharmacy and dispensed against a prescription written in your name — not sold as a "research only" product with no oversight.
The short answer: unregulated supplements make claims nobody checks, "research only" vials sold online carry no prescription, no pharmacy and no accountability, and a prescribed DSIP is compounded by a licensed 503A pharmacy against a provider's order written for you.
| Oral supplement | "Research only" vial | Prescribed DSIP (Rx) | |
|---|---|---|---|
| What it is | An unregulated oral precursor | A vial sold without a prescription | Compounded DSIP dispensed on a provider's order |
| Licensed provider reviews you | No | No | Yes — before anything is dispensed |
| Compounded by a licensed pharmacy | No | No | Yes — U.S. 503A |
| Your name on the vial | No | No | Yes |
| Dose set by a prescriber | No | No | Yes |
| Legal to sell for human use | As a supplement | No | Yes — by prescription |
The simplest test of any peptide seller: is your name on the vial? A "research only" label means no prescriber reviewed you, no licensed pharmacy compounded it, and nobody is accountable for what is actually inside.
Three steps: answer a short set of medical questions, connect straight to a licensed provider on a live video call, and if they prescribe, a 503A pharmacy compounds and ships it.
A short private medical questionnaire — your history, current medications and what you are hoping to address. It takes a couple of minutes.
You go straight onto a video call with a provider licensed in your state — no appointment, no waiting room. They review your answers with you and decide whether DSIP is appropriate.
If they prescribe, a licensed U.S. 503A pharmacy compounds your vial and ships it discreetly, with your name on the label.
It's for adults who want DSIP prescribed and compounded properly rather than bought from a grey market. Whether it is appropriate for you is a decision for the provider who sees you on the call.
DSIP was isolated in slow-wave sleep research, which is the origin of the interest in it.
Reviewed on a live call by a licensed provider, compounded by a 503A pharmacy, dispensed with your name on the vial.
Amount and schedule are set by your prescriber.
DSIP is compounded as a subcutaneous injection.
DSIP is not FDA-approved and is not approved to treat insomnia or any sleep disorder. The human evidence is limited and inconsistent. If you have a persistent sleep problem, that deserves evaluation by a clinician rather than a peptide. If you are pregnant or breastfeeding, have an active cancer diagnosis, or have significant kidney or liver disease, tell your provider on the call. New or unexplained symptoms should be evaluated by a clinician rather than self-treated.
You answer a few questions, meet a licensed provider on a live video call, and — if they prescribe — your medication is compounded and shipped to your door. No insurance required, no in-person appointment, no waiting room.
Answer a short set of private medical questions. One peptide per visit — each needs its own provider consultation.
You are connected to a provider licensed in your state on a video call, usually within seconds. Approval is never guaranteed.
If prescribed, your vial is compounded by a 503A pharmacy and ships in plain, unmarked packaging to all 50 states.

DSIP is compounded as injection. The amount and the schedule are set by the provider on your video visit — we deliberately do not publish a dosing regimen here, because that is a clinical decision about you, not a product specification.
DSIP is not FDA-approved and is not approved to treat insomnia or any sleep disorder. The human evidence is limited and inconsistent. If you have a persistent sleep problem, that deserves evaluation by a clinician rather than a peptide.
Reported effects are most often related to the injection itself or to infusing too quickly. They can include:
Tell your provider about every condition and medication before starting, including pregnancy or breastfeeding. Stop and seek care for signs of an allergic reaction — rash, swelling of the face or throat, or difficulty breathing. For emergencies call 911.

DSIP is a nine-amino-acid peptide first described in 1977, isolated from the cerebral venous blood of rabbits during induced slow-wave sleep — which is where the name comes from.
The human evidence is limited and inconsistent, and no sleep indication has been established. It is not approved to treat insomnia or any sleep disorder.
No. A persistent sleep problem deserves proper evaluation. Raise it on your video visit — the provider can tell you whether a peptide is the wrong tool for what you are describing.
No. After the questionnaire you are connected to an available provider on a video call, usually within seconds — there is no scheduling step and no waiting room.
Every peptide requires its own provider consultation, so each one is its own visit. Complete this visit and you can return to the peptide shop to start another.
