DSIP

A naturally occurring peptide your brain already uses to regulate deep, restorative sleep. DSIP doesn't sedate you — it works with your body's own sleep rhythms to improve the quality and depth of sleep you get, reducing the time spent in shallow rest and increasing the repair and recovery that only happen in deep sleep.

Delivered as a nasal spray — no needles, no preparation required. Spray before bed, lie down, and let it work.

How DSIP Works

Sleep isn't just one thing — it cycles through different stages throughout the night, and the most valuable stage is deep sleep (sometimes called slow-wave sleep). This is when your brain consolidates memories, your body repairs tissue and muscle, and your immune system does most of its maintenance work. Most people don't get enough of it.

DSIP — Delta Sleep-Inducing Peptide — is a naturally occurring neuropeptide that your brain already produces to help regulate this process. It works by supporting the brain's own mechanisms for transitioning into and sustaining deep sleep, rather than forcing sedation the way sleeping pills or antihistamines do. The result is more time in genuinely restorative sleep, without grogginess, dependency, or rebound insomnia when you stop using it.

DSIP also helps regulate cortisol — your primary stress hormone — which is one of the main reasons people struggle to fall or stay asleep. High evening cortisol keeps the brain in an alert state when it should be winding down. By supporting a calmer nervous system response, DSIP addresses one of the root causes of poor sleep quality rather than just masking the symptoms.

Why a nasal spray? The nasal lining has a direct pathway to the brain through the olfactory nerve — one of the most efficient routes for peptides that work on the central nervous system. Delivering DSIP nasally means it absorbs quickly and reaches its target more effectively than oral routes where digestive enzymes break it down. Lying down immediately after spraying enhances this absorption further.

What DSIP Does For You

Most people notice improvements in sleep depth and morning restfulness within the first 3–7 days. Stress, mood, and cognitive benefits build over the 4–8 week course.

Deeper, More Restorative Sleep

DSIP increases the proportion of time you spend in deep sleep — the stage where your brain and body do most of their repair and maintenance work. Users typically notice they wake up feeling genuinely rested rather than just having been unconscious for hours. The difference is particularly noticeable in the first week.

Reduced Stress & Anxiety

DSIP directly supports the body's ability to reduce cortisol — the stress hormone that, when elevated in the evening, prevents the nervous system from settling into sleep mode. This makes DSIP particularly helpful for people whose sleep problems stem from an overactive stress response rather than a purely sleep-timing issue.

Sharper Focus & Better Mood

Sleep quality and cognitive performance are directly linked. Better deep sleep means the brain's glymphatic system (its overnight cleanup process) runs more effectively — clearing metabolic waste that accumulates during waking hours. The downstream effect is noticeably sharper focus, better memory recall, and a more stable, positive mood during the day.

Recovery During Sleep

Deep sleep is when growth hormone is released, muscle tissue is repaired, and the immune system consolidates its response to the day's exposures. More time in deep sleep means more time in this repair window. Athletes and physically active users often notice DSIP as a meaningful complement to their recovery protocols — particularly when combined with products like CJC-1295 & Ipamorelin.

Hormone Balance

Poor sleep and chronic stress are two of the most disruptive forces on hormone balance — they elevate cortisol, suppress growth hormone, and interfere with thyroid and sex hormone regulation. DSIP addresses both simultaneously: improving sleep architecture and dampening the cortisol response that drives the stress-sleep-hormone disruption cycle.

Brain Protection Over Time

Chronic sleep deprivation accelerates neurological aging — it increases oxidative stress in the brain and reduces the clearance of proteins linked to cognitive decline. DSIP has neuroprotective properties that reduce this oxidative stress, supporting cognitive resilience over time. This is particularly relevant for anyone using DSIP as part of a broader longevity or anti-aging protocol.

How to Use DSIP

DSIP nasal spray is simple to use — no needles, no mixing, no preparation. Spray into your nostril before bed and lie down immediately. That's it.

Days 1–3 · Starting Dose

1 spray into 1 nostril at night

Start with a single spray into one nostril, 30 minutes before bed. Lie down immediately after to optimize absorption through the nasal lining. This lets your body adjust to the peptide before increasing the dose. Most people notice an improvement in sleep depth within the first few nights at this level.

Day 4+ · Full Dose (if needed)

Up to 4 sprays (2 per nostril) nightly

If you want to increase the effect, you can build up to 4 sprays per night — 2 into the left nostril and 2 into the right. Many people find 1–2 sprays is sufficient for meaningful benefit. There is no requirement to reach the maximum dose — use the amount that produces the sleep improvement you're looking for. Continue daily for 4–8 weeks.

What	Amount	Details
Starting dose	1 spray, 1 nostril	First 3 days — let your body adjust before increasing
Full dose	Up to 4 sprays (2 per nostril)	Increase only if you want stronger effect — 1–2 sprays works well for most people
When to use	30 min before bed	Then lie down immediately — staying upright reduces absorption
Frequency	Daily	Consistent nightly use produces better results than occasional use
Duration	4–8 weeks	Continuous use allows full sleep pattern regulation to take effect

Lie down immediately after spraying. This is important — not just a recommendation. Lying down immediately prevents the spray from draining down the throat and ensures it stays in contact with the nasal lining where it can absorb into the bloodstream and brain. Sitting or standing for 10–15 minutes after spraying will significantly reduce the benefit you receive.

Step-by-step how to use your spray

1

30 minutes before bed, prepare your space

Have the spray bottle ready on your nightstand. Get into bed or a position where you can lie down immediately after spraying. Don't spray it standing in the bathroom — you need to be horizontal within seconds.

2

Gently blow your nose if needed

Clear your nasal passages lightly so the spray can contact the nasal lining directly. Don't blow hard — just clear any obvious obstruction.

3

Insert the nozzle and spray

Insert the spray nozzle just inside one nostril, tilt slightly toward the outside wall of the nostril (not straight up), and press down on the pump once. Inhale gently through your nose as you spray — this carries the mist further into the nasal cavity.

4

Lie down immediately

As soon as you've sprayed, lie on your back or side. This is the most important step — horizontal positioning ensures the peptide stays in the nasal lining rather than draining. Stay still for at least 5–10 minutes.

5

If using multiple sprays, alternate nostrils

For a 2-spray dose, do 1 spray per nostril. For a 4-spray dose, do 2 sprays in each nostril sequentially. Lie down after your final spray and stay horizontal.

Common Questions

Is DSIP a sleeping pill? Will it knock me out?+

No — DSIP is nothing like a sleeping pill. It doesn't sedate you, it doesn't force unconsciousness, and it doesn't leave you groggy in the morning. It works by supporting the brain's own sleep-regulation mechanisms, helping you transition more easily into deeper sleep stages rather than chemically overriding your nervous system. Many users describe it as feeling like their brain finally "decides" to sleep properly, rather than fighting against wakefulness.

Why do I have to lie down immediately after spraying?+

The nasal lining absorbs DSIP directly and efficiently — but only if the liquid stays in contact with it. When you're upright, gravity pulls the spray down the back of the throat where it gets swallowed and largely broken down before it can reach the brain. Lying down immediately after spraying keeps the peptide in the nasal cavity, where it can absorb into the bloodstream and follow the olfactory pathway to the brain. This step makes a meaningful difference to how effective each dose is.

How soon will I notice a difference?+

Many people notice something within the first 3–5 nights — typically a sense of falling asleep more easily, sleeping more continuously, or waking up feeling more genuinely rested. Sleep quality improvements often appear before mood and cognitive changes, which build over 2–4 weeks of consistent use. The effect compounds over time — consistent nightly use for the full 4–8 week course produces noticeably better results than occasional use.

Can I become dependent on it or will I have trouble sleeping when I stop?+

No — DSIP does not cause dependency and there is no rebound insomnia when you stop using it. This is one of its most important advantages over traditional sleep aids. Because it works by supporting your body's own sleep regulation rather than overriding it, stopping DSIP simply removes the support — your sleep may return to its baseline, but it doesn't actively worsen. Many people find that after a full course, their sleep patterns have genuinely improved and they need less support to maintain good sleep quality.

I only need 1 spray — do I have to work up to 4?+

Not at all. 4 sprays is the maximum — not the target. Many people find that 1 or 2 sprays produces all the sleep improvement they need. Start with 1 spray for the first few nights, assess how your sleep changes, and only increase if you feel you want a stronger effect. There's no benefit to taking more than you need, and the right dose is the lowest one that gives you the outcome you're looking for.

What if I have vivid dreams or feel drowsy the next day?+

Vivid dreams in the first few nights are normal and typically reflect the increase in deep sleep and REM activity as your brain adjusts. Most people find them interesting rather than disturbing, and they usually settle after 3–5 days. If you feel mildly drowsy the next morning, try spraying earlier in the evening or reducing to 1 spray. These effects are temporary and resolve with continued use as your sleep architecture normalizes.

Can I use DSIP alongside other Bespoke Biology products?+

Yes — DSIP pairs especially well with CJC-1295 & Ipamorelin (the growth hormone stack), since both work during sleep and reinforce each other: DSIP increases time in deep sleep, which is when CJC-1295 & Ipamorelin's growth hormone release peaks. NAD+ & Glutathione also complements DSIP well, supporting the cellular repair and brain protection that deep sleep enables. Let your provider know your full protocol to confirm timing and combination are right for your goals.

Is it safe to use if I take other sleep aids or medications?+

Always discuss this with your healthcare provider before combining DSIP with any other sleep aid or medication. Because DSIP works through a different mechanism than most sleep medications, direct interactions are unlikely, but your provider should know everything you're taking to give you appropriate guidance — particularly if you use prescription sleep medications, antidepressants, or anything that affects cortisol or the nervous system.

How should I store my DSIP spray?+

Store your DSIP nasal spray in the refrigerator at 35–46°F (2–8°C) when not in use. Protect it from direct light and heat. Do not freeze it. Before using, you can let it come to room temperature briefly for comfort — cold spray in the nostril is fine but room-temperature feels slightly better. Check the expiration date on the bottle and follow your provider's guidance on how long an opened bottle should be used.

Side Effects to Watch For

DSIP nasal spray is very well tolerated. Side effects are uncommon and typically resolve with continued use:

/Temporary nasal irritation or dryness — usually mild and fades within a few days
/Vivid dreams in the first few nights — a sign of increased deep sleep activity; typically settles after day 3–5
/Mild drowsiness if taken too early in the evening — try delaying to closer to your actual bedtime
/Rare: mild headache or nasal congestion — uncommon and typically short-lived

These effects are uncommon and resolve with continued use. If anything feels unusual or persistent, contact your provider.
