I know back in my day Wazza recommended 200-400 mg's a day dosage. I personally took 300mg's a day myself along with all the rest on his Pharmacy of Supplements and Drugs List!!!!
I also added Vit D to my regime and 1/2 a tsp of fresh Royal Jelly too a day (this particular one was for egg quality, which just for the record tasted vile like rancid beeswax!!!!..Blegh!!!).
I took all of it for almost 7 months non-stop between Cycles 4 and 5.
