I have heard of the shree brand as it was promoted big time with one of the coaches in jhb as the "best brand he has ever used." Blhow ever I see he is now sponsored by another brand and still using monster doses with his clients. So to be honest I don't know of their quality, all I know is people he worked with use massive doses of any brand that if they don't get results I would be shocked.
I have been using upa since 2018 exclusively, and I can tell you that hands down it is legit, and the results are there. Other than that evidence, I got nothing for you.
It would be amazing to see someone sending all the brands for testing, but get 3 of their products done. Anavar, primo and test as majority of these new labs that pop up underdose those products or even fake them. I'm using upa test e, primo and masteron currently and I'm getting the results so I know their products are legit.
