Seriously, there is repping a product and then there is this...
For someone to really compare a "natural" product to ECA or Clenbuterol is just OUTRAGEOUS in my opinion... Here is his question: "I'm looking into the best option out there for cutting, here's what I'm looking into. and then some people suggest Erase + T2 + OEP? Over ECA or Clen? Seriously? A natural OTC stack x Not so OTC stuff and we are giving the OTC an edge?
Granted, YOU may rather take the stack as in "I do not enjoy the anxiety that comes with ECA"; "I don't enjoy being jittery all day thanks to ECA" ; "I don't like the cramps that come with Clen" ; "I don't have means of getting ahold of some Clen". Ok, if that was the case for any, sure, by all means get some Shift + T2 + OEP. Just please don't try to sell someone on how that stack is better than ECA stack or Clen because that is just crazy. Is it a good stack? Yes. Is it a great stack? Perhaps. Better than ECA? Doubtful. Not to mention, if you really wanna go all out, do ECA + T2 and knock your socks off.
It almost reminds me of USP Labs a while back claiming that they were releasing a 90% concentrate Coleous Forksilii (sp?) product and claiming gains better than Anavar. Like, seriously bro? Or if someone were to ask "Hey, what should I do for most strength? H-Drol, Epistane or Anabolic Pump + Prime + Powerful? And along came a USP Lab rep and said "Oh, AP+P+P is by far the best choice here, it will put the most muscle on you!"
Let's be serious here now, come on. I respect the opinions and not wanting to go a certain route, but to me is a stretch to put any natural product ahead of Clen or Ephedrine.
So to answer your question: The best one of the trio is Clen, by a long shot. It comes with some downsides that you may not appreciate, cramps are annoying, the shaking and jittery is also annoying and you will be warm as hell throughout the day. Not to mention not as easy to get a hold of.
ECA is a great stack and you can dose it to fit your needs. I take every 3 hours and works like a charm for me. Some people add Yohimbine, which is to the point that I mentioned before, perhaps you would do yourself a favor stacking the Alpha T2 with it. You could very well run Erase + Alpha T2 + ECA, just taking off the OEP and replacing with ECA. Another good combo is Shift + Alpha T2 + ECA (I have ran that with great success).
Hope this helps.
