Mrjack - there are a few varieties if "Indo" and some are more stimulant than others.
There are two things to keep in mind when looking for stimulation from Kratom.
One is dose, generally speaking 2-5 g's provide stimulation. Larger doses become more sedating.
Also the strain, Thai varieties usually are more stimulating than the others, followed by Malay, then Indo.
Another thing to bear in mind is people tend to get very different effects from Kratom. Some find Indo ineffective, while they swear by Bali, which I find considerably less potent than Indo.
There are 20+ alkaloids found in Kratom and the ratio's vary from strain to strain and time of year picked. Aswell as method of drying.
Personally, I love Kratom/mitragyna speciosa. But be warned, a lot of people find it addictive and my advice to anyone considering it, is stay clear of the extracts and stick to plain leaf.
