here is why i believe efedrine is much better than the others:
efedrine is not only exellent for that loss but also superior to any drug as a pre workout booster. (well.. said aside speed or coke).
its short half life makes it superior to the others as it leaves the system very fast.
relatively safe if used in moderation. of course, you will hear of protstate issues that aroused from efedrine use but when a bodybuilder uses steroids for 10 years then complains about efedrine causing his prostate problems.. see what i mean.
dnp... just too risky... will also burn some muscle unless backed by anabolics.
clen... good stuff. just as good as efedrine for fat loss but doesnt have the pre workout boost that efedrine offers.
t3.. too risky... no boost.... way catabolic.
i think its all summed up.
please, dont hesitate to add comments and/or questions as i'm sure some of you will.
