And here's the first update! I'm only a week in but holy sh*t if this isn't ever working. I've had tenderness in the chest and scrotum and wild fluxuations in libido over the past week. I've had some voice cracking as well which I was not expecting and at times I can not hit as low of notes as I'm used to being able to. My voice feels thinner (less resonant) also, but I could just be imagining it.
But that's not what you're here for, is it? 
(well, it's not what I'm here for, anyway)
So check this out! 
My nipples have literally doubled in size. No pumping or excessive tweaking, though I have used a PM serum a few times and I've been drinking a fair amount of milk.
Excuse my split ends, some day I'll have a stylist give me an actual cut, but I'm social distancing.
