About DSIP Source

The precursor problem

I expected a peptide's known sequence to come with a reasonably settled account of its origin. The 2006 DSIP review undid that expectation: no conclusively identified gene, precursor protein or specific receptor, after an already substantial history of experiments.

That gap gives DSIP Source its subject. To my mind, locating that protein would be more satisfying than extending the catalogue of possible benefits. It would answer a question that remains open even when an experiment produces a measurable effect.

Those awkward peripheral findings appeal to me: cortisol staying unchanged after an ACTH measurement falls, or rat tissue releasing an opioid peptide when direct opioid-receptor binding was absent. Those results make the biology more interesting and the sweeping claims harder to sustain.

DSIP Source

DSIP Source is a personal commentary on published research. “Source” refers to the molecule's biological origin and to the records that might help explain it. There is no DSIP supply service here: no stock, dispensing, shipments or treatment appointments. I cannot provide a prescription or choose care for a reader.

The pages are not medical advice. A paper about sleep cannot examine a person with a sleep problem, account for their medicines or investigate an underlying disorder. Those decisions require the clinician responsible for that person's care. DSIP has no FDA-approved medical use.

Unresolved biology

An identified precursor, a specific receptor and a consistent explanation of the body's DSIP production would materially change this account. So would a convincing modern human trial. An answer supported by that work would be a welcome replacement for an unresolved entry.

A result in an altered peptide, animal model or isolated tissue can still be interesting while that work remains unfinished. The research record is full of such leads. A source that changes a factual claim, or a broken link in that record, can be raised through the corrections page.
