What time of day did human ipamorelin research test?
The human study located for this page does not establish a best bedtime, meal interval, or workout schedule. It studied short intravenous infusions at different dose levels in healthy male volunteers, not a daily at-home timing routine.
What the human study measured
In a 1999 dose-escalation study, eight healthy men were studied at each of five infusion rates. Growth hormone release followed a single episode, with a reported peak at about 0.67 hours after infusion. The study measured pharmacokinetics and hormone response; it did not compare morning with bedtime dosing, test meals as a timing variable, or measure sleep or exercise outcomes.
