Question looking to get my #4 lab tested with purity % (harm reduction)?

[tablet press]

i want to provide the consumer a safe highly almost pure product this #4 chinna white was made fresh to my specs i wanna verify the quality and assure future clients that its Fent free and at least 85%to 98% pure i had the cook brew a batch just for me and made sure it was Fent free so it took 2 weeks to make and land at my door so i need a lab in the USA who can provide a report on % and confirm its fent free...

A basic way to test is utilize test strips to see what the active compounds are, fent test strips are pretty decent at detecting it and test strips which say OPI (opiate) sometimes assist in differentiating it apart if the fent strip says negative. Please be cautious as 95%+ of any opiate these days is synthetic and more likely than not the item you have is fent or an isoton analogue

There are places that do testing on this site, you Mail it in and call it something that identifies it as yours. Costs $100 at one place, but there are a couple
