Kiyoshi top work and also your praise for HOT-ROX Extreme is a big recommendation in my books, since, as you said, you work in a supplement store and have tried everything. I haven’t tried the HOT-ROX Extreme one but might soon - it was banned in Australia but now I am in the UK and everything is legal here it seems, if you can find/afford it.
I would definetely give the Metabolic Drive a go. I am not lactose intolerant and so not a good authority but apart from being a great product I’d expect it to be pretty low in lactose.
There are a number of weird new proteins out there like “pea protein”, rice protein and also one based on hemp … I don’t know anything about them though. I certainly have not tried them.
Please note I don’t particularly endorse those sites, I just googled to get some.
Biotest products are very good quality but they don’t have anything like these yet. Maybe they should make a whey protein with the lactaid build into it! Might be a seller.
Back in Oz I used to use pure hyrolysed whey and pure hydrolysed casein (which was better). OK it is not 100% hydrolysed but it was just the whey/casein, hydrolysed, very low lactose I believe, 0.2% … it was a bitter taste, but you get used to it real fast and start craving it.
The company that sells it also sells Biotest stuff. Of course it is in Australia but I believe they do international orders. Or there might be a similar product in the US, or in fact, Biotest Surge might be incredibly low in lactose too. Or maybe 0.2% isn’t that low I have no idea. I think lactose accounts for about 30% of my calories (just kidding).
Thank you very much for your input!!! I am going to look into Metabolic Drive
