Some human use

It has been used in people, but no trial has settled how much or how often.

The human evidence for DSIP used the intravenous route. The draw worked out here assumes a subcutaneous injection, so the amount is not a direct read-across.

Published research contexts for DSIP describe 100300 mcg per administration. Descriptive only, not a recommendation.

Cleared within minutes in plasma; human estimates are rough.

Human studies in the 1980s administered DSIP intravenously and mostly returned null results on sleep and related measures; no dose-ranging trial fixes a subcutaneous schedule, and the injected figures in circulation are community-derived, so no schedule table is shown.
