I'm going to disprove this with bloods.
I sure do wish for that to happen - I sure do wish I am wrong about this. But as of now, it's one persons opinion over "1000's" of other users.
Regarding UGL's, well yeah, obviously they are not pharma grade, but saying serm's are significantly underdosed, especially the cheap clomid and tamox, is kinda silly. For the part that I have taken clomid and tamox, they have always been effective. Done tons of bloods. Saying all UGL gear is either bunk or severely underdosed, is just plain wrong.
There are not a lot of people in this thread, so there probably wont be much replies, that are antagonistic to your views ... But we can open a thread on this and I dare to presume, that most will confirm the validity of UGL clomid and tamox. It just doesn't pay off for UGL's anymore to fake stuff that much. Demand is high, bad word spreads quickly over the net. Times have changed. Might be different for var or primo for instance, but clomid and tamox, not really.
Go to meso, go to PM, etc. state this facts, as you have done so here. Ask for bloods, ask for cycle's that have had serm's in them.
I do agree that for strictly scientific purposes, everything needs to be tested for purity, but you still can not disregard all the anecdotal evidence, backed up by bloods as falls, due to non regulatory circumstances. If most non scientific evidence points in one direction, you just can't disregard it. That's just silly and it signifies more about your character, or your love for this topic, then you care to realise.
Even if you somehow are able to keep hpta up, again, it's one user over many many other's that haven't succeed. And scientifically speaking, when is something valid? High enough sample pool, research needs to be replicated and it needs to hold up to scrutiny. You use your scientific stance for your own gain and disregard it completely, when it comes to your claims. This logic can just as easily be turned back on to your claims and your personal tests, that you are about to do.
But I digress ... Post your bloods, post your cycle and we will add it to the interwebs circle of infinite knowledge and let the average gym rat decide for him self, what to do with his body.
