Providing you only with 15mg Phentermine capsules, Mirapront is largely sold in the United Kingdom. There is very little information actually available on Mirapront. However, with the lower dosage of about 15mg, they are hoping for a lower incidence of side effects. There is no manufacturing company listed at this time, and there are also no side effects listed. But it should be assumed at this dose that side effects are still extremely likely, and results will still only last for a few weeks at best.
