I just switched from fifty410 to Brello health I seen that they compound there tirzepatide with B6 I’ve never taken that vitamin with tirzepatide however I have taken tirzepatide niacinamide when I was with emerge I was wanting to know what the difference between those two compounds were and if anybody has ever gotten an order from. Brello how is their tirzepatide have you had good results with it? The tirzepatide I was taking before I switched to Brello was with fifty410 and they just gave the tirzepatide with nothing added so I was just curious if anyone knew
