clen brand/manufacturer difference?

[MAXOUT]

is there a difference between Nihfi clen and spiropent? been doing a lot of research on spiropent and it seems to be one of the top choices among board members as well, but alot of my research gives a choice as "Nihfi or spiropent" and i was just curious as to what the difference is?

I wouldn't worry about different brand names as long as their legit.
