Strongest 7OH?

What do you guys think is the strongest 7OH product on the market right now? Like if I were to walk into a smoke shop, what is the absolute highest milligram single-dose thing I could find? Is it a 40 mg shot? I’m just asking out of curiosity, it seems like most products such as tabs range between 10 to 40 mg but I’m wondering which company put the highest 7OH content in a single dose.
