I have found that Red Cross is a very established name in health problems and they have years of experienced doctors with them. The procedures are good and you won’t be let down. It’s cheap too. The only problem is that you will have to run up and down a lot to get medication and paperwork sorted out. There are instances where they provide test results at a later date. Regardless, they will start you on PEP immediately. Pulse Clinic on the other hand is a far newer medical center and they have young but respectable doctors. They give you all the time you need and are willing to answer all of your questions. It’s more expensive than Red Cross but it's the price to pay for quality. I am not endorsing Pulse Clinic in any way, so please read reviews before you go.
