Type
DSIP is a naturally occurring nonapeptide discovered in 1974 in rabbit brain. Originally isolated for sleep-promoting properties, it has diverse neuromodulatory effects including stress reduction, pain modulation, and endocrine regulation without traditional sedative effects.

Overview of DSIP
Modulates multiple neurotransmitter systems including GABA enhancement, NMDA receptor interaction, and endogenous opioid system modulation. Also regulates hypothalamic-pituitary-adrenal axis for stress response.
sleep
- Promotes delta wave sleep, the most restorative sleep phase for physical recovery.
- Reduces sleep latency and nocturnal awakenings without morning grogginess.
- Supports natural sleep cycles rather than forcing sedation like traditional sleep aids.
mood
- Helps regulate cortisol and stress response through HPA axis modulation.
- Supports emotional balance without sedation.
- May help reduce anxiety through neuromodulatory effects.
pain and recovery
- Significantly reduced pain levels in 6 of 7 patients with chronic pain conditions.
- Helps manage withdrawal symptoms in alcohol and opioid-dependent patients.
- Supports post-training recovery through enhanced sleep quality.

PeptideDSIP Protocols
Subcutaneous injection is the standard route. Best taken 30-60 minutes before bedtime. Some prefer earlier evening dosing for gradual onset.
| Goal | Dosage | Frequency | Route |
|---|---|---|---|
| Sleep enhancement | 100 | 1 week range | SubQ |
| Chronic pain support | 250 | 1 week range | SubQ or IV |
| Stress management | 150 | — | SubQ |
| Withdrawal support | 200 | 2 week range | IV preferred |
| Athletic recovery | 100 | — | SubQ |
Reconstitution Instructions
Materials needed:
Steps to reconstitute
- Clean vial tops with alcohol swab and let dry completely
- For 1mg vial, add 1mL bacteriostatic water (creates 1000mcg/mL)
- Inject water slowly down vial side to prevent foaming
- Gently roll between palms - do not shake
- Solution should be clear and colorless
- For 100mcg dose, draw 0.1mL (10 units on insulin syringe)
- Store reconstituted peptide in refrigerator immediately
DSIP Cycle
The DSIP Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.
Taking breaks between cycles may help maintain effectiveness and support better overall results.

Reconstitution Tips
- Use bacteriostatic water (BAC) — contains 0.9% benzyl alcohol for preservation
- Inject water slowly — aim down the vial wall, not directly onto powder
- Never shake — gently swirl or roll the vial until dissolved
- Store properly — refrigerate at 2-8°C after reconstitution
- Use within 28 days — most reconstituted peptides remain stable for about 4 weeks
- Keep sterile — always clean vial tops with alcohol before drawing

Frequently asked questions
What is a peptide dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
