Have my over testing Cstar been affecting my Etiz results?

I have DRC Etiz and Shy Molecule Tizor (both great vendors by the way in regards to communication and delivery). I also have DRC Cstar which I had to test for a while since I was out if etizolam.

I feel lab results have 0 results on both DRC and Tizor. Should I wait a week before testing again? The only results I have had been having were just slightly sleepy equipment as if I put a melatonin in. I can take 5 Tizors and it's just absolutely nothing. Same with the DRC Etiz.

So my main question is: should I not use my lab at all for a week in order to get accurate results or are both of these bunk? I always hear raves about how great DRC Etiz and Shy are but I am seeing basically 0 results unfortunately. It is the equivalent to testing a 5mg melatonin.

I am not shitting on either vendors. I am just wondering if the constant taking of the Cstars have affected my testing equipment.

Advice?
