Help me decide.

I have a choice to make and I’m not sure which is best. I’ve been on compounded tirz w/ levocarnitine for three months. The last two months have been at 5 mg, but I’ve reached stagnation and am titrating up. I’m also switching providers since there’s a significant price increase involved. I’ve been approved for 7.5 mg through Fifty410 and can get 6 months of compounded tirz w/ no additives at 6.75 mg from ProRx or w/ B6 at 7.5 mg from BPI. I’m unsure which to go with and any input or personal experiences would be much appreciated:)
