IV doses of 25-400 mcg/kg for safety studies Important: These are experimental doses used in animal studies and cannot be extrapolated to other species due to significant differences in metabolism, pharmacokinetics, receptor expression, peptide degradation rates, and tissue distribution patterns
Sleeping through that first dose at the new level, then resuming your normal morning schedule the following week, can make escalation significantly more tolerable
