DHC is as strong as hydro and is also time released. i take 4 dhc 60's compared to 6 hydros. phamatico.com, medscorp.com and pharmagroup.com have didor continus its expensive and all three co.'s have been very unreliable lately. medscorp ripped me once and still waiting on my pharmagroup order. it seems spain is becoming as bad as usa since it looks like DHC will be gone for good soon.
