Not working for me?

I have stacked Reta 2 mg the last month on top of 12.5 of tirz with the hopes of kicking weight loss into gear. I do tirz on Saturday and reta on Wednesday. I am just not seeing any difference after a month. I don’t feel anything after the shot like i do with tirz. It’s not impacting my hunger at all.

So maybe I got a bad vial? Maybe I need to increase the dose? Maybe I’m not responsive to it? It’s hard having a research study with only one subject and no controls.
