you will know if your clen is legit trust me. the sides are awful once you get past 40mcg
in the future don't gamble with any drug if you aren't sure about your source. just go to ag-guys.com and buy their clen and other ancillaries. they are 100% legit and have been for years
I have never tried the brand so I can't comment. Your best bet would be to head on over to evolutionary.org and check the source reviews section. See what comes up.
You can legally order clenbuterol as a research chemical liquid from ag-guys.com. They are an approved source of the board.
I haven't used them before so I cannot comment on the legitimacy of the product. I would not use clen ever again but if I had to recommend a source it would be ag-guys. The products I use from them are very good.
