Dosing & Reconstitution Guide

The protocol below uses a 3.0 mL reconstitution volume to keep injection units comfortably above 10 on a standard U-100 insulin syringe, reducing measurement error. Doses are titrated as shown below.

Route: Subcutaneous · Frequency: Daily or 5–10 day cycles · Cycle: 5–10 day cycles

Reconstitution steps

01
Draw 3.0 mL of bacteriostatic water into a sterile syringe.
02
Inject the water slowly down the interior wall of the peptide vial -never directly onto the powder -to prevent foaming and denaturation.
03
Swirl or roll gently until fully dissolved. Do not shake. The lyophilized powder should dissolve completely within 30–60 seconds.
04
Label the vial with the reconstitution date and concentration (1.67 mg/mL). Refrigerate at 36–46 °F, protected from light. Use within 14 days.
Research use only. This protocol is derived from published preclinical and early-phase clinical literature. DSIP is not FDA-approved for human use. This information is not medical advice, diagnosis, or treatment. Consult a qualified healthcare professional before beginning any peptide protocol.

Storage Instructions

Lyophilized (dry powder)
−4 °F
Store frozen in dry, dark conditions. Minimize humidity exposure. Stable for 12–24 months when properly stored.
Reconstituted (in solution)
36–46 °F
Refrigerate after reconstitution. Use within 14 days. Do not refreeze reconstituted solution -freeze-thaw cycles degrade peptide integrity.

Allow refrigerated vials to reach room temperature before opening to minimize condensation uptake. Always inspect for cloudiness or particulates before use -discard if present.

How DSIP Works

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide first isolated from rabbit cerebral venous blood during induced sleep. It modulates GABA-ergic and monoaminergic neurotransmission, with particular influence on delta-wave (slow-wave) sleep architecture -the deepest restorative sleep stage associated with growth hormone secretion and tissue repair.[1]

Research indicates DSIP attenuates HPA axis stress response and possesses analgesic properties in chronic pain models. Its effects on sleep appear to be modulatory rather than sedative -promoting physiologic sleep patterns rather than forcing unconsciousness.[2] The peptide has a shorter reconstituted stability than most peptides (14 days), requiring attention to storage timing.

Observed Effects & Side Effect Profile

The following observations are derived from preclinical literature and limited early-phase human data. They do not constitute clinical claims.

Reported benefits (research literature)
  • Promotes delta-wave sleep architecture -the deepest restorative sleep stage
  • Modulatory rather than sedative -supports physiologic sleep patterns
  • HPA axis stress response attenuation in preclinical models
  • Analgesic properties observed in chronic pain research
Known limitations & side effects
  • Reconstituted shelf life only 14 days -shorter than most peptides
  • Human clinical evidence is dated and limited in scope
  • Effects vary significantly between individuals in reported use
  • Mechanism of sleep modulation not fully characterized
  • Not FDA-approved for any indication

Lifestyle Considerations

While the following suggestions are not protocol requirements, research on tissue repair and peptide efficacy consistently highlights these as factors that influence outcomes:

01
Protein intake. Collagen synthesis and tissue remodeling require adequate dietary protein. Research generally supports 1.6–2.2 g/kg/day during active recovery periods.
02
Sleep. The majority of tissue repair and growth hormone secretion occurs during deep sleep stages. 7–9 hours of quality sleep per night supports the biological environment in which recovery peptides operate.
03
Activity balance. Avoid complete immobilization (which impedes collagen remodeling) and overuse (which re-injures tissue). Progressive loading appropriate to the injury stage supports functional recovery.
04
Stress management. Elevated cortisol chronically impairs immune function and tissue repair. Evidence-based stress reduction techniques support the recovery environment.

Injection Technique

Standard subcutaneous injection guidance from clinical best-practice references.

01
Wash hands thoroughly. Clean your work surface. Gather all supplies before beginning.
02
Wipe the vial rubber stopper with a fresh alcohol swab. Allow it to dry completely before inserting a needle.
03
Draw the calculated dose volume into a sterile insulin syringe. Invert the syringe and tap to remove air bubbles; expel them before withdrawing the needle from the vial.
04
Select an injection site: abdomen (at least 2 inches from the navel), outer thigh, or upper outer arm. Clean with a fresh alcohol swab and allow to dry.
05
Pinch a fold of skin between thumb and forefinger. Insert the needle at a 45–90° angle depending on body fat thickness -45° for leaner individuals, 90° for more subcutaneous tissue.
06
Do not aspirate. Current clinical guidelines do not recommend aspiration for subcutaneous injections. Inject slowly and steadily over 2–3 seconds.
07
Wait 3–5 seconds after the plunger bottoms out before withdrawing the needle at the same angle. Apply gentle pressure with a clean swab -do not rub vigorously.
08
Rotate injection sites systematically with every dose. Reusing the same site repeatedly causes lipohypertrophy (hardened fat tissue) which reduces absorption consistency.
09
Dispose of used needles and syringes immediately in a puncture-resistant sharps container. Never recap needles by hand.

Important Notes

Research use only. DSIP is not FDA-approved for human use. Human clinical data may be limited. Do not use without consulting a qualified healthcare professional.
One syringe per injection. Never reuse needles or syringes. Each injection requires a fresh, sterile syringe to prevent contamination and infection risk.
Shorter reconstituted shelf life -14 days only
Document your protocol. Record daily dose, injection site, and any observations. This supports consistency and allows you to identify patterns or issues over the course of the cycle.
Inspect before each use. The reconstituted solution should be clear and colorless. Discard if cloudy, discolored, or if particulates are visible.
