Frankincense: the Christmas gift for your manhood

Ever wonder why in the Bible Christmas story, an herb called Frankincense was as valuable as gold? It’s because that herb comes from the Boswellia tree resin, and can support a renewed confidence in your manhood.

Boswellia resin extract helps support a healthy, non-inflamed state in your cells[6], which is linked to healthy levels of testosterone.[7]

Today, you can test for yourself the benefits of Boswellia extract, without the expense and inconvenience of finding the Frankincense from the Bible.

I’ve formulated Barbarian XL into an easy-to-take capsule

Just take 2 capsules per day with food. Your body absorbs it quickly, and there’s no aftertaste. It’s that easy!

One dose per day and these hearty ingredients go to work promoting healthy testosterone levels to help you reclaim your manhood. You could soon feel your confidence, energy, and sexual vigor roar back to life!

You’re getting Boswellia resin extract, plus 4 more ingredients that amp up your testosterone:

1Boswellia resin extract

This comes from the same plant as the Biblical herb Frankincense. It supports a healthy, non-inflamed state in your cells[6], which promotes healthy levels of testosterone.[7]


The root of a bell-shaped flower that’s native to India. Medical studies show that Ashwagandha supports healthy testosterone[8], increases muscle growth[9], and decreases stress![10]

3 Tongkat Ali

An herb that grows in the jungles of Malaysia. Tongkat Ali breaks down the “feminine” hormones in your body like progesterone, and metabolizes them into testosterone, restoring your masculine drive.[11]

4 Shilajit

This is a mineral paste that’s found naturally in the Himalayan mountains. It naturally lowers your free radicals, which supports healthy testosterone levels.[1]

5 Korean Red Ginseng

When you steam and dry the root of the ginseng plant, you get red ginseng. Medical studies found that it helps with strong, long-lasting erections, and amps up your sex drive.[5][12]
