Try adding some caffeine. the geranium solo doesn't add a lot of feel if you dont also get some caffeine in with it, even if it is doing its thing in the background. like 100-200mg
Its still working for a lot of its effect, but it doesn't really give off a feel solo. you can try 120, but you may not notice a whole ton more in terms of feel either
I don't think anyone really makes the extract. It would take literally tons of plant material for a serving of methyl-hexamine. (geranium)
A good synthesis should yield a m-hex with a very poignant smell.
Maybe I am wrong, but all of the companies I know are using synthesizes.
