Does anyone have any info regaurding this topic? I take seasonal allergy meds and am just curious if this has any effect on gains etc? Cheers....cache. Oh, and for those of you who have read my posts regaurding injection site inflamation and redness etc, this helps, allot. So, in conclusion I would assume that I am actually allergic to the compound itself or the ester maybe, either way, I took a double dose of Allegra just prior to yesterdays inj and chased it down with a hot compress for 20 min and today, no lump no swelling no pain. This truly is a day for celebration haha....just a personal rant. But as to the question at hand??
