Kosher Supplements
Isolate - https://www.amazon.com/dp/B00MPR1DZ2/?coliid=I1T6M2M23G0AAV&colid=10H8R8SOT4D61&psc=1&ref_=list_c_wl_lv_ov_lig_dp_it , I get the unflavored one as I have a sensitive stomach and prefer to flavor it with my own natural sweetener, which is Peanut Butter powder.
As of writing this, there is not a Cholov Yisrael, Hydrolized Whey Protein Powder product.
Currently, the only Cholov Yisrael products are all concentrates. I doubt there will be a product which will be Isolate soon, as I am under the impression that the vast majority of Jews are NOT lactose intolerant. However, I would also assume that, Ethiopian Jewery are likely to be mainly Lactose Intolerant due to African genetics. I myself am Half-African, Half-European.
The Tribulus I take is Kosher
I would only recommend taking Testosterone supplements before going to bed as doing this will damper aggression which is a side effect of testosterone supplements.
Another testorone focused product coming is Male Energy from Nutri-Supreme.
Cholov Yisreal
This Cholov Yisrael product is from Qualify which has a high certification but doesn't seem to be a Jewish-Centric company.
However, this Cholov Yisreal product is from a Jewish-Centric company but is much more pricey.
I would buy the latter product if it was Hydro or at the very least an Isolate but since I am VERY lactose intolerant, I am buying neither of them for personal consumption.
ToDo: Create a petiton for a Kosher certified Hydrolized whey product are there are currently none on the market.
