    I have been taking about 6 caps regularly for a variety of reasons. I need to give a serious shout out to opms kratom for making my life better. After a few tries, I figured green maeng da capsules are the way to go for me. Can’t do kratom powder which I’ve tried. Getting my kratom from kratomlords is a straightforward no bs experience. That coupled with good shipping makes this place my standard go to.

    Insanely helpful for those not being able to take RX. OPMS kratom capsules are just legendary, this is the best maeng da out there for sure. I buy a few of the large bags every month and it has really helped with my wellness journey much more than any other things I’ve ever tried.

    I am a very hard to please person with a high bar for excellence – opms maeng da capsules definitely make me happy. 3 bags of the 480 caps sees me through a month of varying lows especially since I was hobbling around after a knee replacement and excruciating post op pain. I feel that’s only half the deal, the vendor being consistent makes for the other half of the buying experience. KL comes out way over the top as far as that goes and makes every purchase I make here very satisfactory. I’m going to give both them and the kratom solid five well earned stars.

    Very easy to take since I do not have to put up with the awful kratom powder taste. Works like a charm. I’ve tried quite a few variations of maeng da capsules and always find myself coming back to opms kratom for more. Must be something to it 🙂

    My tried and true go to kratom capsules. Maeng da kratom rules all and opms kratom knows how it’s done best. This is my ten star daily driver.

    Enter opms green maeng da kratom capsules – my highest rated kratom capsules out of 20+ brands I’ve tried. This is my de facto daily driver and the only reason my days go well amidst a whole host of issues. I couldn’t be more thankful and cannot recommend this strongly enough for anyone who needs kratom regularly.

    Finding quality kratom was such a hassle before I stumbled across opms. There are tons of mom and pops home brews brand names that claim yada yada but these guys just deliver. As in the maeng da is excellent. I’ve had them for over half a year and have looked at it closely – and it’s just very very consistent. My search ends here as I hope it does for others.

    It works a gazillion times better than Naproxin or Advil for sure. The only things better than its effectiveness is the super service I got from kratomlords. I’ve been ordering for a year and it’s been the same solid, consistent service each and every time. Opms kratom rocks and maeng da silver capsules are my favorite from their lineup.

    This is how I start my day. I pop in eight of these and I’m good to do till late in the evening. Sometimes I re-dose depending on how my day is but mostly I don’t. Rating these a wholehearted 5.
