It depends on why you’re using it really re effects etc. Ive only tried two tbf. I was prescribed codeine for nearly three years so I used it to get off that. I started first with the Red Sumatra which did the trick but after my first order I went for the FS Bali Gold which was/is much stronger. KUK have have their critics here but in my experience they’ve been awesome. I can’t compare product quality as I’ve not tried any others but it’s good enough to get me off a prescription opioid habit sea
