If you make them tank tops, I'll buy at least 2.
I don't wear T-Shirts in the gym. I only wear tank tops. I'm sure as hell not going to wear a Ttokkyo shirt around in public as if I'm trying to promote steroid use. But I'd wear a Ttokkyo tank top to a gym because only the juicers could know what the hell it meant; it would have more purpose.
I wouldn't wear a shirt that had a huge emblem covering the front. I like what the other bros said about having a small emblem on the left chest then a larger one on the back with "Bboddy by Ttokkyo" The bboddy thing cracked me up! I love it. The dog would be cool to put on the front left chest, but if not... the little emblem would be cool.
You could sell the hell out of them in the bodybuilding community if you had them tank tops. But I don't think you'd even break even trying to sell t-shirts... ask AJC.
You should take payment by
www.paypal.com. Trust me, that is how I take payments and it saves a hell of a lot of time and everything is easy to keep track of. If you use an address, just go to the paypal site and get it from your account. Money orders were a hassle for me.
I think that white or black would go over better than the blue that you were suggesting.
