The underground T3 was way overdosed. Sounds plausible, that's a fear with underground T3 as well as clen. The brewer makes a little mistake and it could kill people.
im not so sure, he was experienced and likely knew what a proper dose of t3 was supposed to feel like. the idea that he unwittingly poisoned himself with overdosed t3 seems like favorable framing.
i think he was just pushing the limit on t3 and it caught up to him
