The Problem

The struggle with cellular
decline

Millions of people struggle to reach their optimal health due to outdated treatments and one-size-fits-all approaches. Your body's chemistry is unique.

DSIP Detail
01

Standard Care Falls Short

Generic supplements and broad advice rarely address the root cause of your specific metabolic or cellular imbalances.
02

Lost Time and Money

You spend years trying unproven methods, only to experience rebound effects or minimal progress.
03

The Need for Precision

Without clinical-grade, targeted interventions, true optimization remains out of reach.
How It Works

Circadian
Reset.

DSIP doesn't just knock you out; it modulates your brain waves, ensuring you spend adequate time in the reparative Delta wave sleep phase.

Delta Wave Promotion

Increases the duration of Delta sleep, the deepest stage of sleep where physical repair and memory consolidation occur.

Hormonal Balance

By normalizing sleep, DSIP indirectly boosts natural growth hormone production and testosterone (LH) release at night.

Stress Reduction

Lowers corticotropin-releasing factor, effectively reducing cortisol levels and minimizing the physical impact of chronic stress.

Pain Management

Exhibits significant analgesic properties, making it useful for patients suffering from fibromyalgia or chronic pain disrupting sleep.

DSIP FAQ

DSIP in India — your questions, answered.

Doctor-reviewed answers covering dosage, results, side effects, legality, sourcing, cold-chain delivery and how the Longegra DSIP program works for patients across India.

DSIP is a nine-amino-acid neuropeptide that crosses the blood-brain barrier and promotes deep, restorative slow-wave sleep — the sleep stage most critical for memory consolidation, GH release and physical recovery. Unlike sleep medications, DSIP does not sedate; it improves sleep architecture.
Typical dose is 100–500 mcg subcutaneous injection 15–30 minutes before bed, 3–5 nights per week. It is not designed for nightly use — your physician will set an intermittent schedule to prevent receptor desensitisation.
Melatonin shifts your circadian rhythm but does not deepen sleep. Zolpidem (Ambien) induces sleep but fragments sleep architecture and impairs memory. DSIP works specifically to extend slow-wave (deep) sleep — the stage that actually drives recovery. Many Longegra patients use DSIP as a way to get off sleep medications.
DSIP has a very clean safety profile in long-term Russian and European clinical use. No dependence, no morning hangover, no impairment. Mild headache and vivid dreams are the most-reported effects.
Yes. DSIP is prescribed and dispensed through Longegra's licensed network of Indian physicians under the existing pharmacy and telemedicine framework (the 2020 Telemedicine Practice Guidelines and Drugs & Cosmetics Act). Every DSIP order requires a valid prescription written by a doctor registered with an Indian State Medical Council after your intake review.
Yes — DSIP is a prescription-only therapy. Longegra is a doctor-led peptide program, so you will not see a "buy DSIP online India" shopping cart anywhere on the site. Instead, you complete an online medical intake, our physician reviews your history and biomarkers, and only then is a prescription issued and the medication dispatched.
