I wouldn't say its weaker if you take comparable doseages. IDK what 80-100mcgs of clen is in terms of albut doseage. I see it as it's only weaker if you don't dose it every 6-7 hours. So if you took if before bed probably it would prob be very similar for results. That's my theory at least.
I think most take albut for the reason that it wears off so they can sleep bc clen can be harsh for many.
But then again one could have a higher beta receptor binding affinity thus rendering it stronger, which would be clen if I had to guess.
You ever run albut tice?
