i have come across a sale of these 2 products on a buy 1 get one free, so i would get a total of 4 bottles for 80 bucks, i know fizogen is widely considered crap, but others say they have decent product just way overpriced, like MT. any thoughts on wether this stack would be worth the 80 bucks, at bottle dosage it would last 40 days.thank u EZ
