STUDY AMOUNTS, NOT USE INSTRUCTIONS
DSIP Dosage Reported in Human and Animal Work
The amounts below came from studies. They don't show what would be safe for any person.
DSIP dosage in a study isn't a safe-use guide
Sleep studies tested DSIP, a body-made protein piece. This page shows you amounts from published work. It identifies the people or animals involved. It also says how researchers gave DSIP.
These facts aren't use steps. DSIP isn't an approved medicine. No study has found an amount known to be safe for people. Effects vary and often don't appear. An animal amount can't guide another animal or a person.
Animal blood loses DSIP within minutes. Old studies used shots or put it into brain fluid. No approved DSIP pill exists. The DSIP half life page explains those animal minutes.
You won't find a personal plan here.
Human DSIP dosage studies repeated one amount
Several human studies used 25 nanomoles per kilogram, a lab count of tiny DSIP pieces rather than a familiar weight. Body weight set the total. The amount went into a vein. People with long-term insomnia slept longer. Waking spells also fell. Researchers first saw better sleep in hour two [2].
A separate trial used 25 nanomoles for every kilogram of body weight. People fell asleep sooner and slept more of the night. Neither side knew who got DSIP or a placebo. A placebo looks like the treatment but holds no DSIP. The gains were modest [18].
A stress study used the same amount. One stress hormone fell. Cortisol kept its normal daily course [4]. During alcohol and opiate withdrawal, everyone knew DSIP was being given. Sickness eased, but the study had no fair comparison group [19].
These old research amounts don't make a safe standard. No modern controlled trial has set one.
You can't turn them into a personal amount.
Animal DSIP peptide dosage differed by test
Animal studies used very different amounts. Cats got 120 nanomoles per kilogram. A nanomole counts tiny pieces rather than weight. A shot placed DSIP under the skin. Deep sleep rose, while dream sleep didn't fall [7].
Female mice got Deltaran in five-day rounds each month. Deltaran contains DSIP. Researchers used about 100 micrograms per kilogram, with each microgram equal to one-millionth of a gram. That worked out to about 2.5 micrograms for each mouse. The study watched life span and tumors [5].
In 2024, a mouse test ran for five straight days. Its liquid was 100 nanomolar, meaning the lab counted how tightly DSIP pieces were packed in the liquid. The figure doesn't tell how much reached each mouse. The mice had been kept from sleep [6].
Animal work put DSIP under skin, through the nose, or into brain fluid. One test passed DSIP through a guinea-pig brain kept supplied with liquid outside the animal. It watched DSIP move into brain tissue.
None of these tests gives you a safe human amount.
No DSIP peptide nasal spray has approval
A DSIP peptide nasal spray may sound simple. Animal researchers have put DSIP into the nose while checking brain harm. Researchers hoped the nose might offer a direct route toward the brain. That was an animal idea, not a reason to try a spray.
No approved DSIP nose spray exists. No controlled human trial has tested one [3]. Researchers haven't found a safe human amount for a nose spray. Research-labelled DSIP products are still sold online. Their strength, contents, and freedom from germs may differ.
Animal blood loses DSIP very fast. That helps explain the interest in another route.
It doesn't show that a nose spray works or is safe.
Fast breakdown led to changed forms of DSIP
Blood proteins break DSIP apart fast. That helps explain why most studies used a shot. Some put DSIP straight into brain fluid. Most work didn't use a swallowed form.
Older papers tried changed forms because plain DSIP broke apart quickly [17]. They didn't set a safe amount for people. In 2024, researchers made another form that reached mouse brains. It lasted longer and cut mouse wake time more than plain DSIP [6]. The work still wasn't done in people.
Labs often keep DSIP as dry powder. They add germ-free water before a test. No approved medicine sets one strength or storage time. Researchers also haven't measured how people clear DSIP.
These studies can't show you how to use DSIP safely.
