If you are in the UK, you can only buy Prime Male from www.primemale.com.
Free Shipping: I highly recommend getting the 2 or 3 month supply option at checkout. These are the only two options that provide free shipping to the UK.
Money Back Guarantee: The product comes with a 90 day money back gurantee if you don’t get results. So even if you get a bigger package in order to claim the free shipping, there is no risk because you just return the product for a refund anyway.
