The OPMS capsules are good, but cost nearly $10 per capsule. They contain 80mg of mitragynine, which is roughly the same in 6g of kratom. If you use 30g a day of plain kratom powder, you'd need 5 capsules at nearly $50, whereas that same 30g of regular powdered leaf would cost $3-4 if bought in bulk.
The OPMS is definitely a cleaner feel though. It will also up your tolerance rather quickly. Interestingly, the best highs ive ever had from kratom were from the regular leaf instead, not the extract. The extracts are also quite abit more sedating than the plain leaf.
Hey Negrogesic ✌
We've discussed OPMS in the past a few times. As far as the nausea goes, I have found the drug ondansetron (zofran) to noticeably reduce nausea from kratom. I have experimented with and without it and I consistently vomit on 15g doses without ondansetron. I have never vomited from kratom while on ondansetron. it is prescription only but it's not hard to obtain. I take it for nausea associated with chron's disease. Ondansetron is a 5ht3 receptor agonist antiemetic drug. I have never received even slight antiemetic effects from antihistamines and I've tried many (prescription and OTC).
I've been using kratom at ~40-70 grams per day for well over 5 years, probably like 8 years now.
Anyway, as of late I have developed a dependency to the OPMS gold capsules. I found a local shop that no shit sells them at 50% the cost we all expect them to be. I cant stop buying them. Been taking 15g red bali/borneo plus 2 OPMS gold each evening and the opioid effects are consistently more pronounced than without OPMS. I haven't gone a day without OPMS in over 2 months

I know I fucked myself a little here.
I achieve euphoria akin to opiates with these things alongside plain leaf, benzodiazepines, and gabapentinoids simultaneously. I don't recommend that combination though as it definitely increases the risk of overdose.
Took 30mg dxm, 4mg chlorpheniramine maleate, 8mg ondansetron, 14g red bentuangie, 3 OPMS gold capsules, 10mg diazepam, and 1500mg gabapebtin this evening. Feeling pretty well right now (be advised, this is an extremely high dose and combination of sedatives - please do not take something like this without tolerance and experience; even then, i can't recommend something like that).
Just thought I'd chime in.
Sekio - I too am curious if the tea can be administered rectaly. Please report back if you try!
