By the way, I'm quite sure that the blue pill DOES NOT come in a bottle. It comes in a pack (4 in one pack) to be exact. I have no idea what you are buying but be careful.
You can buy a 50mg pill in Hong Kong (legit) The 100mg pills are from the States, Canada, Aust. From my experience, a 50mg pill is all you need. It takes about 30 minutes to kick in. When it's in your system, you will feel a little hot and your face may turn a bit red. It doesn't help you shoot more however, you will be much harder.
Oh, if you got heart problems, don't take it. It would look horrible if your heart stops while pumping a WG
