Firstly I'm pretty new to posting here, and wasn't sure whether to start a new thread or revive this one because I feel it's relevant, so I apologize if this has already been discussed and I'm committing any kind of faux pas.
I revived this thread to say that I've had many many, of these (although I prefer the capsules) and what you had is pretty typical for OPMS Black shots. It's pretty thick stuff to the point where it usually sticks to the bottom of the bottom and requires a 'lil rinse and shake to get the rest out.
I don't have the label of one handy, but if it's to be believed, the only difference between the black and the gold (besides more Mitragynine per dose) is the 7-Hydroxymitragynine content.
As you can see there 25 times more 7-Hydroxymitragynine in the black than the gold.
I haven't taken the gold in a while because it's a much more mild experience, akin to large amounts of dried leaf. When I take the black (usually 4-5 capsules) it ABSOLUTELY feels like a full agonist. I'm talking pinned pupils, raspy voice, everything. I would compare it to something like ~30mg of oxycodone but lasting longer. It has given me more or less complete relief from (mild) suboxone withdrawals, and also oxycodone withdrawals, which I am still kind of astounded by.
I'm curious if anybody else is familiar with these OPMS extracts and has had a similar experience as myself in regards to the black being so much stronger, and feeling like a full agonist. The difference in potency between 7-Hydroxymitragynine and mitragynine, and the 25 fold increase between the two, leads me to think that perhaps the gold contains a sub threshold dose of 7-OH, while in the black it's basically primary substance, as opposed to mitragynine, which is why it is qualitatively so much different.
I'd love to hear from you.
