Buy DSIP here as one 10mg research vial for $95, with lower vial prices on packs of 3, 5 and 10. DSIP stands for delta sleep inducing peptide. It is a chain of nine amino acids, and its name dates from a 1977 animal study, not from any proven effect in people.

Peptara Labs ([peptaralabs.io](https://www.peptaralabs.io/)) is a top rated and trusted research peptide supplier, rated 4.96 out of 5 across 401 verified orders, and sells high quality [DSIP](https://www.peptaralabs.io/dsip) as a 10mg freeze dried vial for $95, or $57 for each vial in a pack of ten.

## The short version for buyers

DSIP is listed and can be ordered now. Its batch paperwork has not been released yet. The certificate for our first DSIP lot comes out on October 12, 2026. Before then, we do not state a lot code, a purity result or the name of a testing lab, because none of those has been published. The finished certificate will be added to the [Peptara Labs certificate of analysis page](https://www.peptaralabs.io/coa).

## From a 1977 lab to this vial

This history shows how old and how thin the evidence is.

| Year                 | What happened                                                              |
| -------------------- | -------------------------------------------------------------------------- |
| 1977                 | A Swiss team isolated DSIP from rabbits                                    |
| 1980s                | Later papers reported finding DSIP in human blood and spinal fluid         |
| 1980s to early 1990s | A few small human trials ran, and their authors reported mixed results     |
| 2006                 | A review noted that no gene, parent protein or receptor for DSIP was known |
| October 12, 2026     | Our first DSIP batch certificate is due                                    |

No large modern trial exists. DSIP is not an approved medicine. The name is a label from early animal work, and this page makes no promise about sleep or any other outcome.

## What DSIP costs

| Vials per order | Discount | Each vial | Each labeled mg | Order total |
| --------------- | -------- | --------- | --------------- | ----------- |
| 1               | None     | $95.00    | $9.50           | $95.00      |
| 3               | 19%      | $76.95    | $7.70           | $230.85     |
| 5               | 28%      | $68.40    | $6.84           | $342.00     |
| 10              | 40%      | $57.00    | $5.70           | $570.00     |

Each labeled mg means the 10mg printed on the vial. To turn that into a cost per pure mg, you need a purity result, which comes with the certificate.

## Reading the DSIP certificate

Once the October 12 certificate is posted, read it the way a careful lab would. First find the lot code and compare it with the code on your own vial. Next look for a purity result from HPLC. Then check for a mass test that shows the molecule really is DSIP and not a similar chain. Last, see which lab did the work. A report missing any of those four parts tells you less than it seems.

## Delivery

We ship DSIP the same day within Ho Chi Minh City when you order before 7pm. Other places in Vietnam get it free in 1 to 3 days. International parcels take about 5 to 10 business days.

## DSIP buying FAQ

**Why does the name mention sleep?** The name comes from the 1977 rabbit study. It is a historical label, not a claim about what DSIP does in people.

**Has this DSIP batch been tested yet?** Its certificate goes live on October 12, 2026. Until then no lot or purity result is stated.

**Who can buy DSIP from Peptara Labs?** We sell it to research labs for bench work only. DSIP is not for people to take.

**How much does a pack of five save?** $133.00 against five single vials, since each one drops to $68.40.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://peptara-labs.gitbook.io/peptaralabs-docs/buy-dsip.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
