For bigger volume shots I prefer the outer thighs. Fewer histamine issues that way for me.
Not too concerned anymore but wanted to flag that this kind of thing can occur. Been on glutathione 1200 mg for roughly five weeks, only recently taking the full amount in one go for the last two. Did the glutathione shot then about an hour later pinned 200 mcg of MT1. Had used the same MT1 the three days before with just mild nausea. Roughly two hours after the shot hives and heavy itching broke out across the torso and underarms. Took benadryl plus anti-itch spray and it settled until morning when it flared again. Used an Allegra that was around, finished off the last benadryl and another anti-itch sample. Needed the second Allegra by five o'clock. Since the meds worked and it never reached the face or throat I'm fine but disappointed. Still plan to look into both compounds again once things calm down, just skipping MT1 on glutathione days.
