Hey Mycophile sorry for the delay in my response. My life has many hardships right now and I don't always make it to BL. So if ya already took it I hope it went well.
I've went through 3 of them now and I gotta say I prefer the OPMS gold capsules to the tincture. IME the tincture was more stimulating and kept me up, which kratom never does.
It was pretty damn strong. I never take extract without plain leaf or tea so I cannot tell you how they feel alone. Each time I've consumed the entire shot followed by tea brewed from ~15g powder. It was actually a little dysphoric likely due to the nausea and too much NE release; fortunately I always have ondansetron on hand which works wonders for kratom nausea.
Within 15 minutes I was sweating and buzzing hard, laying on the cold kitchen floor trying not to vomit. It passed and plateaued, but kinda left me at 3 hours with a hangover feeling and just wanting to lay down.
Maybe that was too much for me. Idk. It was somewhat similar to some early experiences with too high of doses; the sweating, dilated pupils, tremors etc. I just know now that I'll be ok so I dont panic.
I believe leaf is ~15mg mitragynine/gram, so 10g kratom is ~150mg mitragynine (if I am correct in the initial dosage per gram, which I may not be).
One of these shots is 118mg, so about 8 grams equivalent by doing the math, but I'd say the entire shot is on par with 10-12g probably, but that's just a (mildly) educated guess.
Something interesting to note is that I used to be addicted to phenibut at 2 - 4g per day for about a year. I have been off of it almost a year (I dont exactly remember how long).
I have extensive experience with gabaergic drugs including benzodiazepines, barbiturates, and the gabapentinoids (gabapentin, pregabalin, phenibut). Phebibut has this distinct feeling to me that I always recognize. It's sort of a heavy headedness and loss of coordination that consistently occurred when I took phenibut. I swear the past 3 days that I've ingested the OPMS tincture extract I have felt that familiar phenibut feeling. Now I am certainly not accusing them of lacing the product with phenibut at all, but it was the strangest thing.
I just poured out 2 OPMS gold capsules and TW'd them on top of 15g maha kali red vein tea after a long day of vyvanse and adderall, ensuring everyone in my family was satisfied all day. Now it's my turn
Merry Christmas and Happy Holidays BL'ers
✌
UPDATE - Feeling way better at T+30 min with 2 OPMS gold capsules and 15g brewed tea than the OPMS liquid tincture.
When I picked these up today the shop owner recommended zion herbals gold reserve capsules and gave me a 5 pack for free. Anyone used these? I'll report back when I do.
