DSIP 5mg reconstitution is simple: add bacteriostatic water, swirl gently, and refrigerate. See a concentration chart, storage tips, and safety notes.
To reconstitute a 5 mg DSIP vial, draw 2.5 mL of bacteriostatic water into a sterile syringe, inject it slowly against the inside wall of the vial, and swirl gently until the powder dissolves. That produces a concentration of 2 mg/mL, or 2,000 mcg per mL. DSIP (delta sleep-inducing peptide) is a lyophilized research peptide that is not FDA-approved for human use in the United States.
Small math or technique errors change how much peptide ends up in each draw. The sections below cover supplies, mixing steps, a concentration chart, storage, and safety. Clean technique is the most important part of any dsip reconstitution.
Supplies Needed for a 5 mg DSIP Vial
Gather everything before you open the vial. Working quickly reduces the time the powder is exposed to room air.
- The 5 mg DSIP vial (lyophilized powder)
- Bacteriostatic water (0.9% benzyl alcohol) or sterile water
- Alcohol swabs
- A U-100 insulin syringe or a 1 mL syringe with a 25-30 gauge needle
- Clean gloves and a disinfected work surface
- A sharps container
Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits bacterial growth and lets the mixed peptide last longer in the refrigerator. Sterile water has no preservative, so it is best for single-use vials.
A frequent forum question — is reconstitution solution bacteriostatic water — has no single answer, because some suppliers use the terms interchangeably. If you are comparing products, reconstitution solution vs bacteriostatic water for peptides is a common search for that reason. Always read the label and confirm the preservative content.
Step-by-Step DSIP Reconstitution
- Wash your hands and wipe the work surface with an alcohol swab.
- Swab the rubber stopper of the DSIP vial and the water vial. Let both dry for 10-15 seconds.
- Pull air into the syringe equal to the volume of water you plan to add (2.5 mL of air for 2.5 mL of water).
- Insert the needle into the water vial, inject the air, invert the vial, and withdraw the water.
- Insert the needle into the DSIP vial at a slight angle. Aim the stream of water at the glass wall rather than directly onto the powder.
- Remove the needle and swirl the vial in a slow circle. Do not shake it.
- Write the date and concentration on the vial, then refrigerate it immediately.
Never shake a peptide vial, because agitation can damage the peptide chain. The powder should dissolve in under a minute; a faint haze can take a few more minutes of gentle swirling.
DSIP 5 mg Concentration Chart
The table below shows how much diluent changes the concentration of a 5 mg (5,000 mcg) vial. The last column shows the amount in a 0.1 mL draw, which equals 10 units on a U-100 insulin syringe.
| Diluent Added | Concentration | Peptide per 0.1 mL (10 units) |
|---|---|---|
| 1 mL | 5 mg/mL (5,000 mcg/mL) | 500 mcg |
| 2 mL | 2.5 mg/mL (2,500 mcg/mL) | 250 mcg |
| 2.5 mL | 2 mg/mL (2,000 mcg/mL) | 200 mcg |
| 3 mL | 1.67 mg/mL (1,667 mcg/mL) | 167 mcg |
| 5 mL | 1 mg/mL (1,000 mcg/mL) | 100 mcg |
| 10 mL | 0.5 mg/mL (500 mcg/mL) | 50 mcg |
A 5 mg vial contains 5,000 mcg of peptide, so the total amount does not change — only the volume you draw changes. If you change the diluent volume, a bac water reconstitution calculator can convert milligrams to micrograms per unit for you. Rounding errors are common when people do the math by hand.
Storage and Stability After Mixing
Refrigerate reconstituted DSIP at 2-8 °C (36-46 °F) and keep it out of direct light. A dark box or a refrigerator door with minimal temperature swings works well. Avoid leaving the vial at room temperature for long periods.
With bacteriostatic water, a reconstituted peptide is usually stable for several weeks when refrigerated. With sterile water, the lack of preservative means it should be used within days. Freezing reconstituted peptide is generally not recommended, because ice crystals can degrade the peptide.
Bacteriostatic water is not the same as sterile water, and that difference directly affects how long a reconstituted vial stays usable.
Discard the vial if you see cloudiness, particles, or a color change. When in doubt, throw it out, because a new vial is cheaper than a contaminated injection.
Safety, Legal Status, and Common Mistakes
DSIP is sold as a research chemical and is not approved by the FDA for human use. Human safety and dosing data are limited. Because human data is limited, any dsip 5mg dosage should be discussed with a licensed healthcare professional.
Common mistakes include:
- Shaking the vial instead of swirling it
- Using tap water or saline instead of bacteriostatic water
- Spraying the diluent directly onto the powder
- Forgetting to swab the stopper
- Reusing needles or sharing vials
- Storing the mixed vial in a warm place or in sunlight
Do not combine DSIP with other peptides in the same vial, because different peptides can interact or degrade at different rates.
Side effects of DSIP in humans are not well characterized. Anyone using it outside a research setting should consult a healthcare professional and follow local laws. This article is for informational purposes only and is not medical advice.
Frequently Asked Questions
How much bacteriostatic water should I add to a 5 mg DSIP vial?
A common choice is 2.5 mL, which gives 2 mg/mL (2,000 mcg/mL). You can use 1 mL for a stronger concentration or 5 mL for a weaker one, as long as you recalculate the units per draw. There is no single correct volume, only the concentration that fits your measurement tool.
How long does reconstituted DSIP last in the refrigerator?
With bacteriostatic water, most researchers store it at 2-8 °C and use it within roughly two to six weeks. Sterile water offers no preservative, so the same vial may only be safe for a few days. Follow the supplier's storage instructions and discard any vial that looks cloudy.
Can I use sterile water instead of bacteriostatic water for DSIP?
Yes, sterile water can dissolve the powder, but it contains no preservative. That means bacterial growth is not inhibited, so the vial should be treated as single-use or short-term. Bacteriostatic water is the more common choice for multi-draw vials.
