If we're defining the silver bullet as something that is DIY-able and will castrate you easily and painlessly, then perhaps this is not it. However, due to the change in the tissue of my testicles that I've already noticed, I'd say this quite possibly could have the potential to possibly castrate (or at least reduce T levels significantly), though painless it may not be. My second injection wasn't because of any question on whether or not the CaCl will work (though we still don't know for sure!), more just that I keep struggling to get enough CaCl into one of my testicles (and furthermore, noticed that the one I did get enough into, only one half seemed to react, at least outwardly, to the injection - the half that immediately surrounded the injection site).
I'm 7 days post-second-injection, and currently in no pain. They're still tender when manipulated of course, but that's the extent of it. I'm still waiting for them to be less tender to fully feel out the right testicle (the one that got the full dose the first time and half reacted) and see how the other half of the tissue feels. I'm hoping it is hard/tough feeling and misshapen as the lower half is. My left testicle, the troubled one, when I manipulated it very gently, felt different than before. Not completely numb, but it felt similarly hard, though to a lesser extent, as the right one. So that's good news. I threw out my bottle of CaCl, and I'll be waiting another 2-3 months to see what happens from here before I try anything else. I've got 10 hydrocodone stashed away for whenever I may decide to inject again, if at all.
I'm fully expecting to eventually need surgical removal of my testicles. My hope is that, as SplitDik said, I can damage them to the point that a urologist will recommend surgical removal and it will be covered under insurance (When I do get some again!). Considering how damaged my right testicle feels at the moment (hard, lumpy, misshapen), I'd say that's a damn good possibility

. If not, I'm currently working on building my credit (I'm young, 21, only 1 year of credit so far. Just unsecured my first credit card!) and hopefully in the next two years I'll be able to take a loan out for what I'd like to do (About $10k for breast augmentation and orchiectomy). This little experiment was just to hope to damage them enough that their testosterone output will be severely diminished (or best case scenario: completely stopped) until then.
Anyway, as far as my testicles go, not much else to report. As I said, I've got no major pain, just tenderness. I'm waiting a couple more days before I try manipulating them a bit more and feeling out what they've done. My epididymis is swollen again on the left testicle, just like before, and my right testicle has a hydrocele that is slowly dissipating, also the same as before. The hydrocele was the largest about day two (probably about the same size as my testicle, completely surrounding it in a good cushion of fluid, mostly towards the side that faces my body), and at this point (Day 7), is about 1/3 of that original day 2 size. It took about 1.5 weeks to fully disappear the first time (though the swollen testicle remained).
I'll keep everyone informed and post another update sometime next week. I'm still very happy with the outcome, regardless. It was worth the pain, and doesn't seem to have any major bothering effects at this point. Just to state again, as posted many pages ago, the damage from CaCl can take up to 60 days to come to fruition. As SplitDik has posted, it disrupts cell regeneration from the salt buildup, and slowly kills the testicle that way, not like alcohol where the damage is sudden and acute. So there's little point in rushing to conclusions at this point. We will have to wait and see.
Thanks, all! And goodluck.
