Multiple doses? Maybe Opko Healths "CTE" technology it acquired when it bought Prolor would be of benefit. Dr. Frost has and is applying it to many things including vitamins and various drugs to keep them in the blood stream longer. I believe it extends the half-life by double in vitamins and drugs like Vitamin B called Niagen by Chromadex, Vitamin D called Rayaldee by Opko, HGH CTP (still in ph 3 trials) by Pfizer, and Niraparib by Tesaro. All are showing great confidence in results. Might be a WONDER DRUG in combo with A 3-71!
