Your medications have high therapeutic index.
Atenolol and Amlodipine are the most dangerous weapons.
The recorded deaths i found for Amlodipine both were accompanied by SNRI's. (PMID: 16839474)
Atenolol barely has any academic papers on its toxicity. I DID find that Atenolol + Amlodipine is a dangerous combination but not very well documented.
Losartan is useless for this purpose.
Do you mind telling us your dose count for all three drugs?
As for fentanyl, many dark net markets refuse to sell it.
I am not responsible for your actions and neither will i say direct strategies but always know that many people have asked for how to get plugs and they get answers
