When to take albuterol?

[Kob]

hey im a new to this forum and excuse my english, im from spain
I have albuterol on hand so i was thinking to run 3 weeks on (except sunday and saturdays) and 1 week off.

My question is because the short half life of albuterol, when i have to take it?
i was thinking 4 mg in the morning and 4mg or 8 mg (depending the sides) after workout. Is this correct?

Also, i have yohimbe hcl so i want to take it on the week off, is this a good combination or it may saturate the adrenals?

thanks and excuse my english again lol
