Ok so my dad has a nice big beer guy that he just can't seem to get rid of. I told him I can help him by puttin him on a Clen cycle. He will be taking Clen and keto but I'm not sure the doses for the keto and is it everyday at night? I'm starting him off at 20mcg of Clen a day and raise it gradually. He is also a smoker so I'm nervous about tht. How long can he run the Clen and keto for without him being at serious risk?
