Mounjaro for maintenance

I have been taking Mounjaro for maintenance purposes. I was originally two stones heavier. Weight Medics are totally professional and the process of reordering a prescription is straight forward and hassle free. I was advised that because of my height and age to try and not go much below 60 kilos and I have tried to follow this guidance as closely as possible.

Fantastic Weight Medics

Weight Medics have been fantastic with their help and advice and are always there to offer solutions to any problems I may encounter. I’m glad I went through them for this important journey in my life as friends, who have gone through other companies, have not had such positive experiences.
