dont waste your money, go with inject. By going oral u use alot of the effectiveness of primo. You have to run 400-600mgs as is so you can imagine how many tabs u have to take.
paper products are excellent especially due to ease of delivery and quality. BUT you can never beat injectable and as your profile states you are in the UK you will not have the problems with customs that paper was designed to ease.
Current working situation makes carrying this stuff a bit of a career risk so paper would be ideal. However, if they are FAR less superior I would be willing to take the risk.
