Has anyone had any experience with this compound? As far as I understand it is uncontrolled in the UK because it does not have and n-akyl substitutions. Any info would be greatly appreciated, Thanks.

Doesn't Britain have derivative laws? 5-MeO-AMT is a true isomer of psilocin, so in that case it would be illegal.

There are a variety of reports on the internet about this compound check out bluelight and erowid also see TIHKAL. Overall reports seem to be rather negative some negative side effects have been reported. There have also been overdoses reported. However it has been sold as "LSD" on blotter and sugar cubes and thus people were taking multiple doses. I have no personal experience with this compound however I bet that like many things if taken at the right dose it probably could be enjoyable. Positive reports do exist. SWIM would just start with a very low dose 2mg and work her way up.

Many types of isomers exist therefore the term "true isomer" is a bit ambigious. 5-MeO-AMT is a structural isomer of psilocin but not a positional isomer. In the US law positional isomers are specifically mentioned for mescaline and psilocin (for example) however the term structural isomer is not used. A positional isomer and structural isomer differ in that in a positional isomer only a few functional groups are switched around whereas a structural isomers may lack completely the parent skeleton and have completely different functional groups yet the two compounds still have the same molecular forumla. Many things can be structural isomers (only requirement is having the same molecular formula) thus it would be ridiculous and difficult to make structural isomers illegal. US law says positional isomers, not sure about UK but I bet it is similaur.

In SWIMs opinion 5-MeO-AMT is not a positional isomer of psilocin as the skeleton differs and the functional group changed (from an OH to a MeO) however SWIM is sure that if they wanted the government could find a chemist who would say otherwise (although they would be wrong ). Thus it would come down to who has the better experts (most $ to spend). Unless SWIM is planning to import large quantities it is unlikely that the gov would target someone in possession of a personal amount of an ambiguous compound (although you never know).

I would suggest staying far, far away from 5-MeO-AMT. No entheogenic effect, mostly takes the form of strong visuals. In my own experience, and that of everyone I've spoken to, a persistent headache for the entire 14-20 hours it remains in your system.

UK does have analogue laws applying to DMT, Psilocn, DET, αET and:

"any compound (not being a compound for the time being specified in sub-paragraph (a) above) structurally derived from tryptamine or from a ring-hydroxy tryptamine by substitution at the nitrogen atom of the sidechain with one or more alkyl substituents but no other substituent;"

AMT and 5-MeO-AMT have not alkyl substituents on the nitrogen atom therefore it technically is not covered.

Examples of analogues which would be covered.
DMT, DET, DPT, DiPT, DMiPT etc... all have alkyl chains or branched chains attached to the nitrogen

Interestingly Diallyltryptamine and 5-MeO-DALT is apparently uncovered buy this law because unsaturated allyl groups are not akyl, if you know what I mean.

There are a lot of Chinese, and some American, labs offering 5-MeO-Amt. SWIM is going to do a lot more research before SWIM even thinks about ordering any though.
