Sounds like you got a clen by mistake or something, although that would have been 200mcg. I've done 200 drol ED two different occasions, 100mg per sitting, and it does ZIP to any kind of heart racing and it never killed my appetite. Some people do get lots of sides from drol, high BP (mine does go up), loss of appetite and lethargy - I dont get that at all.
Heart racing and occasionally being mildly jumpy though sounds like clen to me.
His clomid is probably good, I trust many of his tabs but not the drol. Heard way too many negatives and I ran that little survey about 2 years ago, so I basically wasted my dough on that one. At that time for me finding drol tabs under $2 each was not likely to happen, so I took a risk. His dbols were legit but 50mg a tab means cutting up lots of bits unless you are a high doser, I run 25mg for the whole day.
His batches just vary, supposedly he has something like 5-7 outfits at any one time making his goods. Sometimes you can judge by the color if its a good batch or bad, or just plain not as potent (more recent dbols people said felt like 30s). His accutane is the only thing I really stocked up on 500 tabs at a time, anything else nowdays though I just buy powder unless I'm getting a good deal on it.
IP is a risk, so seriously unless you know its legit dont stock up on it, and the drols have been labeled bogus for years now and I'm not exaggerating when I say years. If you ask around if you find anyone who can say something good about them in the last 2-3 years, you found someone I didn't.
Cost of the powders is the same so either a lab screwed him on a huuuuuuuge batch or maybe its his doing, I have no idea. He does so much volume he can afford to lose people, so it matters to him very little I'm sure, he is considered the first UG lab.
So just to recap:
If I can run half a gram of drol in a single day (10x50 = 500mg) and feel not even a SLIGHT hint of something, its not even a friggin 5mg dbol.
