Does PTM7950 and thermal grizzly ptm perform similar?

I ordered ptm7950 from china about a month ago they delivered it yesterday but i didn't get the results i expected, it performed even worse than traditional paste so it is a fake one sadly. And I know how to apply PTM properly as I've done it 5 times before to my laptop and my friends laptops too when I ordered a big and legit one. I asked all my friends and they say temps are the same as 1 year ago. I sold my old laptop and bought a new one so I wanted to use PTM on this one as well but I got a fake ptm sadly and I don't want to wait for another month of shipment. I can get thermal grizzly ptm from the tech store tomorrow and I wanna ask if waiting another month of shipment is worth it over just getting thermal grizzlys ptm. And there is also the doubt that if i order from china again it can be fake again
