"There are athletes who are full-out drugs cheats, there are athletes who would never take anything and there are athletes who would push the boundaries and take things that I consider unethical," she added.

In March, Pavey spoke out after hearing about "the number of athletes reportedly taking thyroid medication".

"Some might be legitimate but I find the situation worrying," she added.
