What an unusual strain this is, it's not like any other strain I've ever tried. First of all, it looks really fluorescent green and also kind of smells that way, very strong and fresh, more fresh than any i've ever smelled before (it is a new and fresh batch that's just in, after all). It's like walking in the jungle, picking a leaf, tearing it up and smelling it. Perhaps it is the freshness that is part of its distinctness.
With 5 grams my experience was as follows.
The taste is VERY strong and bitter. I have my own ways of masking the taste of Kratom completely, but this is the first time that that didn't work. The onset was strong and it was hard to pinpoint how long this took (my usual way of measuring doesn't seem to work with this strain), I would estimate it at 20 or 30 minutes. New to me was that I had to yawn a lot during the onset, almost as if I had taken a psychedelic.
Other things I noticed was feeling some warmth in my stomach and extremeties and a little heart discomfort. A striking thing was that time seemed to go faster. Painkilling properties were good, as was the energy. Not as much euphoria and moodlift as I would have wanted. I expected a Green Malay like experience, but this was different. The overtone is stimulation, I felt very alert for a long time. It's more of a neutral energy than a 'stupor-of-happiness' energy, so probably good to work, exercise or study on. My pupils were not overly constricted.
At the end I developed just a slight headache and felt a bit 'crashy'. All of this leads me to believe that this strain has a lot of affinity to the dopamine and also κ-opioid receptors (and maybe some to the adrenergic and perhaps even serotonergic receptors) and not so much to the μ-opioid receptor.
