You can use this site for phentermine refills. You'll get the 30mg not the 37.5mg. The pills work perfectly fine, 100% genuine. I ordered 10/07 and received, 10/13. This is like my 3rd order with this site. Communication is excellent, you have a money back guarantee, you get to pay with your credit card and it ships within the US, what more can you ask for. Prices are not cheap, but for the service and quality what can you expect.
Also their pain relief like the percocets are also excellent. I received a white oblong pill imprinted with IP 204 on them. 10/325mg. If you ever speak to the guy ask them what is the best price for the percocet because on the site it says $550 but I got them for $450 :)
Definitely will continue to use this place until exhaustion.
