Ephedrine/Clen cross tolerance with amphetemine

**zaneisgreat** · 07-07-2011, 11:02 PM

Hello. Can someone please elaborate on the relation to the two different classes of drugs?

Everyone is quite familiar with the fat loss + weight loss that you'll get from ephedrine/clen or amphetamines and how they lose effectiveness over time... hence the need to cycle off.

My main question is how a transition from a full dose ECA stack to running amphetamines would fare. Would the amphetamine already be less effective because of how the body was recently affected by ephedrine?

We do not discuss amphetamines here.

amphetamine vague and does NOT imply recreational usage. Many drugs like ephedrine are closely related to amphetamine in structure and effects but it's very hard to find citations of cross tolerance between the two.

maybe so. it may not imply recreational useage, but most of the time it does. therefore, we don't discuss it here.
