Mainly compounded medications are usually cheaper/and they can compound different types of meds that are individualized for that person. There are some where their OHIP does not cover medications especially if being prescribed by a trt clinic. I personally do not trust the quality/potency of medications from compounding pharmacies. Not saying they are all not reputable but they are far and few. I live in Hamilton.

Mainly trt clinics have a working relationship with a specific compounding pharmacy. Most family physicians/urologists/endocrinologist tend to prescribe big pharma meds! Not trying to deter you from using a compounded med just do your research and try to find a reputable pharmacy if you choose to take that route.
