There's a massive difference between generic brands

I'm a pharmacy whore. That and they'll randomly switch my brands out of nowhere. For years I was on the yellow 8's (alvogen?) Those were great, almost stimulating, more energetic feeling. A few times I got swapped back to name brand, surprisingly bad, very groggy tired feeling. Super sleepy. About 8 months ago they hit me with Dr. Reddys, despite horror stories, they've actually been pretty good. Very motivated feeling from them, good clean energy. They must have finally got the formula right.

A week ago I filled at rite aid and they hit me with "Ingenious". Awful. Dog shit feeling. Dragging ass, very VERY tired. It's like gravity was multiplied. It's not psychological either because they looked identical to Dr. Reddys, after 2 or 3 days of feeling like complete s*** I read the package and noticed it was a completely different brand. Swapped back to my remaining old prescription and boom, WORLD of difference in the way I'm feeling. Wtf. I actually felt high off the Dr. Reddys. Back to having energy again.

I have enough leftovers to carry me through until my appointment tomorrow, hopefully I can burn the remaining ingenious up by mixing them with the good ones daily until those pieces of shit are completely gone.

Just my experience, something like 6yrs on suboxone now. Each company/brand has slightly different molecular formulas it seems, I speculate some are synthesized different, slightly different compositions. Never thought they'd be so different.
