Zentch labs anyone?

Hi all, again still feeling my way into this site so apologies for anything that’s not in line with site rules.

I’ve started a cycle and had some feedback on moderating it slightly but just want to know if anyone has used zentech before?

Got it in the uk from a guy who has sorted other labs line organon sis aburahain and other stuff that turned out fine so no reason to think otherwise.

Just wanted to know if anyone can give any feedback as struggling to find much online.

Cheers in advance
