Good Primo? Any lab suggestions?

Looking to run primo for the first time, but I know globally alot of batches are bunk.

any lab recommendations?

be careful thats all I can say, it seems to get proper primo is a mission.

I recently bought Primo from a reputable SA brand and was bunk. Did not test it but the effects were really a concern. PS: i have used before with no problems.
better stick with the basics
