I’m sure you’ve seen that guy at the gym who’s always whipping out his silverback gorilla impression, strutting about with his chest pushed out in an attempt to assert dominance. Or maybe you’re that guy, and you’re doing it to attract the ladies (or men, it’s 2018) by making them think you’re the manliest of all.

But what exactly does manliness constitute?

From a scientific point of view, testosterone is what makes men stronger and leaner than women. It is also the thing that contributes to their supposed virility. Naturally, it is assumed by many that the more testosterone you have, the more ‘manly’ you are.

Accordingly, men who lack in this department often look to alternatives like pills, gels, or even testosterone injections. Here in Southeast Asia, some men are also known to take traditional remedies to supplement their masculinity and sexual performance.

One such product is the root of Eurycoma Longifolia, better known as Tongkat Ali.
