PM's if best on this....

Looking for high grade/Pharma grade maybe of liquid C and V in the USA... Tuff looking online as everyplace I research, has some sort of bad rep along the way.
Kinda frustrating but hey this is how it goes when I don't run along the typical paths to get this stuff.
trying chems r x and I am still not sure on the quality.

Any ideas?? PM's if you prefer.
Thanks folks!
