Samples outside the 90–100 range are clear fakes. I can’t stress this enough. I mentioned the best providers in 2020 earlier. It is said that Quick Fix is among the few fake urines on the market that you can cool or heat daily without compromising the sample’s validity and authenticity. If you decide to get a kit from Quick Fix so you can heat and cool the sample as often as you need to, you should also get their leg strap or additional heating pads.
