Thanks; I read the story you linked. It mostly reads as a hit piece centered around various legal allegations tied to stringent confidentiality agreements. There isn't much substance beyond that. The article briefly discusses some vague customer complaints about allulose-directed side-effects from his 'longevity mix', but the actual complaints are incredibly vague and you could attribute side-effects to or from basically any supplement. The article is basically a long-form screed saying over and over "he makes you sign confidentiality agreements".

I don't like Bryan Johnson per se, I just don't think that mal-intent has been substantiated.

For your second claim, I had to use ChatGPT to source it. It turns out that there was a problem with an earlier batch of one of his many supplements being out of spec per the COA. This is common and not unusual. He provides lab testing and COA for his current supplements. The unusual part is that anybody even ever knew his supplements were out of spec because companies don't really publish COA - and people knew because he did publish COA.
