Banned by wada but not banned for possession by FDA. And still not “really” an amphetamine. The alpha position has an amidogen chain and then connected to that is a Methyl chain, not simply a methyl chain. That makes it different.
You said “used to” meaning “can’t be found anymore in the US” as I understand it.
Methyl synephrine is deffo still around though. Ephedrine is not. Not in the US in supplements. We get Sudafed, pseudoephedrine instead marked as “ephedra extract” in supps.
Oh well.
Im not sure where you are still finding this stuff. it was awesome. like super ephedrine. pass me a link if you find it.. but i personally have not seen this in 5+ years, even though this happened in 2016:
Under existing law, including the Dietary Supplement Health and Education Act passed by Congress in 1994, the FDA can take action to remove products from the market, but the agency must first establish that such products are adulterated (e.g., that the product is unsafe) or misbranded (e.g., that the labeling is false or misleading).
While methylsynephrine was listed as a dietary ingredient on product labeling, the substance does not meet the statutory definition of a dietary ingredient. The Federal Food, Drug, and Cosmetic Act defines a dietary ingredient as a vitamin; mineral; herb or other botanical; amino acid; dietary substance for use by man to supplement the diet by increasing the total dietary intake; or a concentrate, metabolite, constituent, extract, or combination of the preceding substances. Methylsynephrine does not fit under any of these categories, rendering misbranded any dietary supplements that declare methylsynephrine as a dietary ingredient.
the following companies were warned in april of that yr.

so technically its not a viable supplement anymore, or ever really... it was a misbranded drug which is illegal to sell as supps.
