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.

Why people ask about it

Why does DSIP come up?

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.

✔A provider decides, not a quiz

Every DSIP prescription here follows a review by a licensed provider of your health history, current medications and goals. If it isn't appropriate for you, it isn't prescribed.

✔Compounded, not a research chemical

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.

Know the difference

Prescribed DSIP vs. supplements and grey-market vials — what's the difference?

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.

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.

How it works

How does getting DSIP actually work?

Three steps: answer a short set of medical questions, a licensed provider reviews them, and if they prescribe, a 503A pharmacy compounds and ships it.

I

Answer a few questions

A short private medical questionnaire — your history, current medications and what you are hoping to address. It takes a couple of minutes.

II

Meet your provider live

A provider licensed in your state reviews your answers online — no appointment, no waiting room. They decide whether DSIP is appropriate.

III

Compounded & shipped

If they prescribe, a licensed U.S. 503A pharmacy compounds your vial and ships it discreetly, with your name on the label.

Who it's for

Who is DSIP for?

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 reviews your visit.

✔Interested in the sleep and recovery category

DSIP was isolated in slow-wave sleep research, which is the origin of the interest in it.

✔You want a real prescription

Reviewed by a licensed provider, compounded by a 503A pharmacy, dispensed with your name on the vial.

✔You want the dosing decided for you

Amount and schedule are set by your prescriber.

✔You prefer an injectable

DSIP is compounded as a subcutaneous injection.

✕When it's not the right fit

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 in your answers. New or unexplained symptoms should be evaluated by a clinician rather than self-treated.

How to get it

How do I get DSIP online?

You answer a few questions, a licensed provider reviews your answers, and — if they prescribe — your medication is compounded and shipped to your door. No insurance required, no in-person appointment, no waiting room.

A few questions

Answer a short set of private medical questions. Add as many peptides as you like; one checkout, and a provider reviews each.

Using it & safety

How is it taken, and is it safe?

DSIP is compounded as injection. The amount and the schedule are set by the provider who reviews your visit — we deliberately do not publish a dosing regimen here, because that is a clinical decision about you, not a product specification.

Safety & side effects

⚠ Not a treatment for insomnia

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:

  • Redness or soreness at the injection site
  • Daytime drowsiness
  • Headache
  • Vivid dreams

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 FAQ

What is DSIP?

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.

Does DSIP actually help you sleep?

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.

Should I use this instead of seeing someone about my sleep?

No. A persistent sleep problem deserves proper evaluation. Raise it in your online visit — the provider can tell you whether a peptide is the wrong tool for what you are describing.

Do I have to book an appointment?

No. You complete the questionnaire online and a licensed provider reviews it — there is no scheduling step and no waiting room.

Can I order more than one peptide?

Yes. Add each one to your cart and check out once. A provider reviews every treatment in your order.
