I wonder if those who ordered 30mg and received red tops were sent the wrong ones? I ordered 20mg because it was the only MG I hadn't seen complaints about and was getting desperate at the time.. for 20mg they sent me red caps and it seems to be working great. I'm a slow loser due to PCOS/insulin resistance and taking it has helped break a stall I was going through.. I've lost 5lbs since starting it. I know that's not a lot to some, but since November I've only lost 35lbs, and it's taken 2 years (prior to Nov no glp) to lose 85lbs.. like I said slow loser. So either maybe they started sending the red tops as 20mg knowing they were underdosed 30s, or they weren't sending the correct ones to those ordering 30s.
