Where to buy phenolphthalein in Markham?

Hey guys,

I read that phenolphthalein can help with flexibility. Does anybody know of any stores in the area that carry this stuff?

I’ve got baseball EVERY DAY and figured it’s time to up my game to the next level. Only problem is that I’ve maxed out my jelqing flexibility, so I’ve plateaued with my batting. (especially sound, I grunt soooo loud when I swing)
