Pro Chem is underdosed on their oils, they have fucked a few batches up and landed people in A&E. They try to blame it on counter fit but it comes from the same half arsed lab in Manchester. It used to be a good lad back in the day but its gone down big time, plenty of guys not been dialing in on stage and looking shit as a result, allot of people been getting really bad pip especially from there One Rip shit, my mate couldnt walk of this as his arse swollen like a balloon! For your glutes to swell like that there is like 7+ % BA in there. Glutes are tought to that stuff. As for their orals one word SHIT.
Rohm, same shit different name, used to be good, gone pants, lots of speculation about them being the same lab because they use chromo vials, same rip tops etc.. Either way, junk.
Wild Cat, under dosed, simple. No horror stories of yet but it not top quality.
Linxus, shit loads of fakes, lots and lots, just not worth gambling with no more.
MTS spot on as far as UGL go, like I said you need to go DIRECT because people have been know to play around with them and unless you getting it direct you cant be sure, they selling allot of good products and upsetting allot of the labs above so you can be sure of some shit to be about to try disrupt them. There a few big US private chefs and MTS are up there with them, they opperate very well and are very humane, they will give out 100 vials when they build a new blend just to get feed back before releasing it after their sponsered fellas have been on it. You can believe what you want but I know this opp very well and it is as good as it get in the UGL world.
As for global brands well there that many that just pop up out of no where. The Pharma stuff is heavily faked also. Stay clear of B.Disp.. it is good IF you get the legit lab but they got opp problems and 90% is shit, B.Dragon same storey. Genza is hit and miss but even if you hit its nothing special. STAY CLEAR of Balkan like your life depended on it!!.. there that many labs popping up and going it just hard to keep track. My best advice is either get in with a good UGL (hard to find) and stick with, get a good chef and stick to him or cook your own but you will need good hook ups to get solid steady supply
As for your floater, lax storage conditions could be the answer if it was genuine.. It gets too cold the powder can drop out of solution and form waxy lumps, crystals etc, their can even be seperation. Stuff can grow in the oil like in any steroid if the conditions are poor. Depends whats in it and end of the day it depends where it come from.
