A DSIP peptide dosing chart with typical research doses, reconstitution math, timing, and cycle lengths, plus safety notes for this non-approved peptide.
Most published DSIP peptide dosing charts list research amounts between 100 mcg and 500 mcg per day, given as a single subcutaneous injection in the evening. DSIP, or delta sleep-inducing peptide, is a nine-amino-acid compound that researchers have studied since the 1970s for sleep and stress-related endpoints. None of the amounts in these charts have been approved by the FDA for human use.
What DSIP Is and Why Doses Vary
DSIP is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from rabbit brain tissue in 1977. Its plasma half-life is short, roughly 15 minutes, but researchers report that sleep-related effects can persist for hours after a single dose.
Because DSIP is not a licensed drug, no official dose exists. Protocols come from small animal studies, older human trials run in Europe and Russia, and vendor-supplied research notes. That is why dsip peptide dosing ranges so widely from one chart to the next.
DSIP Peptide Dosing Chart at a Glance
The table below summarizes the amounts that appear most often in research write-ups and peptide community references. Treat every figure as a starting point for reading, not as a recommendation.
| Protocol | Typical research dose | Route | Frequency | Notes |
|---|---|---|---|---|
| Low-dose sleep model | 100 mcg | Subcutaneous | Once daily, 30–60 min before bed | Appears in older dose-translation work |
| Standard research protocol | 200–300 mcg | Subcutaneous | Once daily in the evening | Most frequently cited range |
| Higher-dose protocol | 400–500 mcg | Subcutaneous | Once daily | Reports of vivid dreams and next-day grogginess |
| Intranasal protocol | 100–200 mcg | Intranasal | Once daily | Split between nostrils; absorption is variable |
| Cycled protocol | Same daily dose | Subcutaneous | 5 days on, 2 days off | Used in anecdotal logs to limit tolerance |
No protocol in this table exceeds 500 mcg per day, and larger amounts are not supported by published DSIP research.
Reconstitution Math: From Milligrams to Micrograms
Most DSIP ships as a lyophilized 5 mg vial, and most dosing confusion comes from unit conversion rather than from the peptide itself. One milligram equals 1,000 micrograms.
If you add 2 mL of bacteriostatic water to a 5 mg vial, the concentration is 2,500 mcg per mL. On a standard U-100 insulin syringe, that works out to:
- 5 units (0.05 mL) = 125 mcg
- 10 units (0.10 mL) = 250 mcg
- 20 units (0.20 mL) = 500 mcg
Keeping a peptide dosing chart pdf on hand makes those conversions easier to double-check, especially when a vial is reconstituted with a different water volume.
The same math applies to an aod-9604 peptide dosing chart or to any other research compound sold in lyophilized vials. Concentration always equals total peptide divided by total liquid.
Timing, Frequency, and Cycle Length
Timing matters more with DSIP than with many other research peptides because the compound is tied to sleep architecture.
- Evening dosing: most protocols place the dose 30 to 60 minutes before lights out.
- Once daily: split or multiple daily doses are rare in the literature.
- Cycle length: anecdotal logs often run 4 to 6 weeks on, then 1 to 2 weeks off.
- Consistency: researchers tracking sleep data keep the injection time fixed to reduce variables.
By contrast, a peptide dosing chart tirzepatide reflects FDA-labeled titration steps for a prescription drug, and that schedule should never be mixed up with research-peptide charts like this one.
How to Read a Peptide Dosing Chart Correctly
Charts are only as good as the units behind them. Before following any number, check four things:
- Is the dose written in micrograms or milligrams? A decimal error changes the amount by 1,000 times.
- Does the chart state the reconstitution volume? A 5 mg vial in 1 mL is twice as concentrated as the same vial in 2 mL.
- Is the syringe U-100 or U-40? Unit markings are not interchangeable.
- Does the chart list the route? Subcutaneous, intranasal, and oral doses are not equivalent.
Any chart that skips these details should be treated as incomplete.
DSIP Peptide Benefits Reported in Research
Published findings on dsip peptide benefits are preliminary and come mostly from small studies. Commonly reported areas include:
- shorter sleep latency and fewer night wakings in some older trials
- changes in cortisol and other stress-hormone markers
- analgesic effects in animal pain models
- antioxidant activity in cell studies
These results are not proof of a treatment effect in humans, and DSIP has never completed the FDA approval process for any indication.
Safety, Storage, and Legal Status
DSIP is not FDA-approved for human use in the United States, and it is sold as a research chemical rather than as a supplement or medication. It should not be injected or ingested outside a supervised research setting.
Side effects reported in older human studies included headache, nausea, and next-day drowsiness. Anyone considering DSIP for a sleep concern should speak with a licensed healthcare professional about approved options first.
Storage matters as well. Lyophilized DSIP is stable at room temperature for short periods but is usually refrigerated for long-term storage, while reconstituted vials are kept at 2–8 °C and used within a few weeks.
A DSIP peptide dosing chart is a reference tool, not a prescription. Verify the math, keep the dose constant, and treat every published number as research context rather than medical guidance.
Frequently Asked Questions
How much DSIP peptide is typically used in research?
Most research references place DSIP between 100 mcg and 500 mcg per day, usually as one evening subcutaneous injection. There is no FDA-approved dose, and DSIP is sold only as a research chemical. Anyone seeking treatment for a sleep problem should ask a healthcare professional about approved options.
Is DSIP peptide legal in the US?
DSIP is not an approved drug or dietary supplement, so it cannot legally be sold for human consumption in the United States. It is widely offered as a research chemical, which means buyers handle a product that the FDA has not reviewed for safety, purity, or dosing accuracy.
How long does DSIP take to work?
In older human studies, sleep-related changes were reported within the first night or after a few consecutive doses. DSIP has a short plasma half-life of roughly 15 minutes, so it does not build up in the body the way long-acting drugs do. Individual responses in research settings have varied widely.
