The effects build gradually. For me it took about a week and a half, though others say up to four weeks. I have had a bruise-like mark near the injection site a few times, so I would guess the patch is normal unless other symptoms appear.
Began my dose Sunday evening and saw strong hunger reduction Monday and today. Tonight though I felt quite hungry again, so wondering if that means the effect is fading. Also noticed a mark or patch right beside the injection area and want to know if that is typical or a reaction. Photo attached below.
