Even if your dose/injection frequency was kept the same did you test at the same lab using the same assays? (My dose/frequency/lab/assays were kept the same.)
Did you inject at the same time each week before getting blood work done at the trough? (Yes)
Did your body weight change during those 6 months? (No drastic change)
Although you stated you lost strength in the gym and felt more lethargic other factors can be at play and highly doubtful anyone using trt doses that is running high-normal or slightly supraphysiological TT/FT levels would lose any strength if they ended up going down to mid-normal levels. (I disagree, each individual body reacts differently to certain doses, and I'm confident with my experience)
Sure if you went from high-normal or slightly supra-physiological TT/FT level down to low-normal or low then it would be expected. (On the contrary, I was on 100ml per week)
We are on trt here using therapeutic doses, not steroids! (You're assuming I'm using professional body builder doses, and I'm only using therapeutic TRT doses)
Regardless in order to properly test for steroid potency/purity, one would need to have that done at a laboratory.(Correct, the only way to know is having the solution tested)
To add to my first response, I did switch from Empower to Perrigo at the 100ml weekly dosage mentioned above. This is my personal experience with the switch, and hopefully it gives you the insight you needed.
Just something I want to do every once in a while, because I occasionally have that little bug in my head. I know it's probably a waste of money, but I want to do it anyway. What kind of services exist out there that offer this? How long does it take and do they respect privacy? And do they...

Otherwise, you are just speculating.
Highly unlikely any big pharma let alone reputable compounding pharmacies would manufacture/produce under-dosed testosterone products.
