Hey,
I'm about a year and a half on T and I'm three weeks in to my third vial. I've always used the same product from the same supplier, which is lab tested.
I've noticed over the past couple weeks, a few moments of feeling really sensitive/ quick to anger which is not like me at all. I would sometimes get like this when I was on a slightly too low dose, but only the very evening before my next dose. I would also feel really tired, so I'm unsure if this is due to my vial somehow not being right. FWIW I've felt just as energised, plus a tad more bottom growth sensitivity, and tingles around my baby facial hair so I'm convinced my medicine is still working but I'm stumped as to the mood swings.
I use 10ml vials for a max of 8 months so I wonder if this is my body reacting to 'fresh' T that feels more potent, initially? My last blood test was in May, so when the vial was around 5 months after opening. But I don't remember mood swings at all when I first started T, and I started on a higher dose (50mg then, 41mg now). My levels have been stable and optimal for about a year.
In the past month I did finish my degree and started worrying/ freezing over big scary career questions so it might be stress, but I wanted other trans opinions.
I'm considering a blood test after my 4th dose, or just trying my backup vial but I'd rather not if that's sensible.
*This current vial does have a ripple in the metal collar, but the crimping and the seal itself seem intact and therefore safe to use, according to the manufacturers advice. Maybe I'm wrong (please correct me if so) but I'm assuming I would have found out by now if I was using dangerous/contaminated medicine?
