It WILL NOT work like that, needs to be injected or put in implants an implanted, regardless of how you do it it needs to be "put in" the body. a SubQ injection is the best way.
putting mt2 under tongue would be a waste.
i mean if you were th eguy making it you coul try taking a SCOOP every day undertongue and hope to notice something.
I LOVE mt2 and have used it many times. you can even get by with 1-2 shots per week if you really want to , *at the building a tan stage* and then 1-2 0.5mg shots everr month after that to help keep it.
