My impression overall is that I wasted my money. I think I took 10 capsules today felt nothing significant. The little drink I got from 711 hit way way harder
Looking at my posts here and it's just like what I said in other threads recently, Kratom was barely perceptible at the dosage levels you tried now. I am NOT recommending this, but 10 grams + is where it "works" for me and I have never had any opiate/opioid tolerance. Even then it's not fantastic but taking a large dose in the morning with a stim has been very nice at times - after not having done any for a long time. I'm in a lot of pain at the moment due to surgery and other prior pains and it would be nice to take a larger dose right now, would kind of need it, even missed a doc appointment today because I just felt in too much pain to go (fuck! it was important too, yearly heart imaging). But at the same time I haven't ordered any these last few absolutely miserable weeks, so that sort of tells me how "good" I think it is...

If the drink you mention was a Kratom drink and you felt it then it was 100% a synthetic spiked 7-OH product. These will be gone from the market in a matter of days probably when they put it in Schedule I, same as Heroin. You don't know how much is in them either, I'd like to have the pure powder so I had control, but that's not kiddie stuff, for real

The previous "gas station heroin," (as it was called in the US) tianeptine sulphate was very nice, might still find it in the states but here in Europe I can't find it on "open" supp sites, not the powder.
Euro anti-depresssant. Users found that if you took 50 or 100mg it had opioid effects. Amazingly the developers of the drug themselves were ignorant of this effect seemingly for decades. Basically it was called a tricyclic anti-d affecting glutamate, serotonin etc, and then...
"Stablon's mechanism involves the drug tianeptine, which paradoxically increases serotonin reuptake in the brain, decreasing serotonin's overall activity and concentration in the synapse. It also has full μ-opioid and δ-opioid receptor agonist properties, which are linked to its potential for abuse and dependency. Additionally, tianeptine modulates glutamate neurotransmission and affects neuroplasticity by impacting AMPA and NMDA receptors."
