I have recently found out that my 70 year old diabetic Dad is taking black market weight loss injections. He hasn’t told me this, I think because he knows I’d worry, I found out from my younger sibling. My step-brother is into bodybuilding and is supplying it. He’s now been taking it for a few weeks and by all accounts is doing well on it. I haven’t brought it up with anyone because I am so upset and worried and I don’t want to fall out with the family. Is it really my business? I’m trying to tell myself not to worry as he’s been on it for a couple of weeks now. I can’t get my head around injecting an unlicensed drug bought from someone with no medical knowledge. My Dad has always been anti any type of recreational drug, he barely drinks. He probably would qualify for Mounjaro or Wegovy through the NHS but he’ll probably not have even heard of it or thought to go to the GP. He trusts my step-brother 100%. I don’t know what to do I’m just sounding off here
