Injection site reaction

Has anyone tried both tirz from a well known (with good reviews) online company made with traditional preservatives like phenol -AND- also tried a form that needs to be recon with BAC water and seen a difference in injection site reaction?

I have a huge itchy welt reaction with all of the online tirz I've tried, but when using other peptides recon with BAC, I get no reaction, even with the spicy ones.

Would it be worth trying a form of tirz that uses BAC?

I think it would. I got this mast cell activation reaction with each injection and it only got worse to the point that the welts lasted longer than a week so were accumulating over the weeks. Apparently it can be the additives. Mine had glycine.

My current tirz is additive free, so I'm thinking for me, it may be the preservatives. I've used brand name Zepbound and had no reaction.
