Statement from Nutropin Depot site (little cropped but gets the message across)
Estimates of relative bioavailability for a single dose of Nutropin Depot ranged from 33% to 38% when compared to a single dose of Nutropin AQ® [somatropin (rDNA origin) injection] in healthy adults, and from 48% to 55% when compared to chronically dosed Protropin® (somatrem for injection).
I'll take the daily injections over the bi-monthly or monthly.
