Regulatory status
Research only
This substance is sold and handled as a research material and is not approved for human use. There is no approved label, which means there is no agency-reviewed information about how it should be handled, who should avoid it, or what happens alongside other medicines.
Not approved for human use
A regulatory status describes paperwork, not safety. An approved compound can still be wrong for a given person, and an unapproved one is neither thereby dangerous nor thereby fine.
Half-life
Short, minutes in plasma (~7-15 min reported); IV or subcutaneous. Half-life is an educational pharmacology figure, drawn from public sources, and is not a schedule or dosing instruction.
Storage & handling
Lyophilized powder kept frozen or refrigerated and protected from light; reconstituted solutions refrigerated, used within a limited window.

01What is DSIP?+
An endogenous nonapeptide first isolated for its association with delta-wave (slow-wave) sleep, studied for sleep modulation and neuroendocrine/stress effects. Its precise mechanism remains incompletely characterized. It is also referred to as Delta Sleep-Inducing Peptide. It is listed here under Cognitive / Longevity as educational reference, which is not a recommendation to use it.
02Is DSIP FDA approved?+
Research only. This substance is sold and handled as a research material and is not approved for human use. There is no approved label, which means there is no agency-reviewed information about how it should be handled, who should avoid it, or what happens alongside other medicines.
03What is the half-life of DSIP?+
Short, minutes in plasma (~7-15 min reported); IV or subcutaneous. A half-life is an educational pharmacology figure describing how long the body takes to clear half of a substance. It is not a schedule and does not imply one.
04How is DSIP stored and handled?+
Lyophilized powder kept frozen or refrigerated and protected from light; reconstituted solutions refrigerated, used within a limited window. Storage conditions come from a manufacturer's own label where one exists, and a compound with no approved label has no agency-reviewed handling instructions at all.
05What vial strengths of DSIP are commonly sold?+
Commonly listed vial strengths are 5 mg. A vial strength is a market fact about how a product is packaged. It is not a dose, and it says nothing about how much of anything belongs in any person.
