if ur product can produce results,if its has a cool name,cool label,it is DOABLE..i say i would go the youtube route,i am doing this soon making my own youtube fitness channel,more of a hobby for me..and if ur product is affordable then there is no reason u could not be succesful..wafter u make ur product,and they WORK what i would do is go to your local gyms front them like a couple bottles for free tell them to seel it for whatever price they want keep all the profit ,see how fast they sell ,then who knows ur gym might be ur biggest custumer
damn great idea bro! IM really wanting to do this, I know it will be hard and may not be succesful at first but i still wanna try. I could even get some reviews together and logs as evidence
