I have some of this green, I find it nauseating at doses higher than 3g. Definitely more sedating. The Red Maeng Da you speak of I have as well, I didn’t find it too bad. Its not as sedating as normal reds but it’s a smooth feeling. The colour of it is just due to fermentation, red strains should always be reddish in colour. If they are green then you’ve been miss sold.
