It is noted that yellow strains (also known as gold) are a man-made creation that were invented during a particular fermentation process. It is the newest vein discovered within the kratom family generating it to be an uncommon product. Maeng Da’s on the other hand, are the most appreciated and well known strains inside the kratom community. The combination of the two are said to be magical. All Maeng Da perks are present in this strain but are boosted because of the fermentation process. The effects of this concoction are very long lasting and stimulating.
