Well, I started injecting IM with some cup. I received from the pharmacy and guessing it started to kick in after 2 weeks or so. I noticed because lifting had gotten easier and I was horny almost 24/7 and waking up with a morning wood everyday. I ordered some products and wanted to use those and save the pharmacy stuff for later on, but after switching I am not noticing any of the effects and what I did start to notice has diminished. It's been about a week and a half since I switched over. I was using propionate and cypionate so I thought it would have been consistent, but does it take awhile to get a new brand's product in your system?
