Best form/brand of Yohimbine

Those who have used or are currently using yohimbe…What form do you find the most effective (sublingual,caps,tabs)??? In addition to that, what brand do you find to be the best? I have used prescription strength in the past (don’t recall mg per tab) and found it to be very effective for fat burning as well as a huge (play on words) libido enhancer with some extra energy as well.
All responses appreciated.

I would try supplement direct. they have a yohimbine hcl 5mg capsules.

In a previous thread the majority preferred Twin Lab as directed on the label.
