Last month, I injected 50iu of botox into my corpus cavernosum. I am pleased with the results on both erectile function and flaccid length.

**Flaccid Hang:** This was the most obvious benefit. Obviously flaccid length is highly variable from day to day, but it seems to average about 0.75" longer than it did before. It also hangs noticeably thicker too, with less retraction and more "heaviness" in the hang.

**Erectile Function:** Defining a 1-10 scale as 0 being no erectile response, 5 being barely adequate for penetration, 10 being so hard it hurts, I'd say my pre-botox norm is about 7.5-8. After bocox kicked in, I'm running about 8.5-9. Noticeable improvement in erection strength and ease of achieving erection.

**Erect Length or Girth Gains?** I don't measure any significant difference in length or girth.

**How It Works:** An erection starts when the smooth muscle in the penile arteries and corpora cavernosa relaxes. That relaxation increases blood flow into the penis, which fills the erectile chambers and produces rigidity. Botox doesn’t directly paralyze those smooth muscle cells the way it does skeletal muscle, but it blocks some of the nerve signals that normally keep them tense. The end result is less resistance to blood flow in the flaccid state and an easier time reaching full vasodilation and erection when sexual stimulus is present. In effect it turns down the volume on the vasoconstriction nerve signals that normally keep you flaccid.

**How I Did It:** I sourced the botox from a South Korean cosmetic retailer that ships to the USA. A motivated person can find these retailers fairly easily by looking into the subreddits on DIY Cosmetics, that's as close as I'm going to get to providing sourcing info. I trust the quality from these retailers, and the price is excellent. *NOTE:* any one pursuing this, whether DIY or through a doctor, I recommend getting the non-complexed form of the toxin, brand name Coretox, to avoid developing antibodies to it over time.

**Injection Technique:** I've done some pretty ballsy shit to my body through the years, but I was definitely a little nervous about this one. I read the procedures from the clinical trials and copied them. I also carefully reviewed internal anatomy of the penis to brush up on the internal structures. It proved pretty straightforward: using a fine gauge needle (31g in my case, the finer the better to prevent the risk of scarring), inject half the dose into each side of the corpus cavernosum roughly 1/3 the way up from the base. Aspirate to make sure you're not in an artery, there is a decent sized artery running in each of the cavernosa. Inject from the 3 o'clock and 9 o'clock positions to avoid the dorsal nerves. Injection depth is about 1/3 of the way into the penis (if you consider full depth to be coming out the other side of the shaft), that puts you close to the center of the cavernosa on the side you're injecting. You can use a gentle tourniquet for 15min afterwards to keep the toxin localized. I would definitely recommend reading the papers on the method before you inject.

**Cost:** The botox cost me $61 per 100iu, so my total cost for the 50iu injection was about $30. I would NOT pay the typical clinical price for it (I've heard $1000 to $2000), but for my cost of $30 I will definitely continue to do it, indefinitely. I will also do 100iu next time for a little extra strength and longer duration of effect.

**Confounders:** I am hanging with medium-heavy weights and also experimenting with ultrasound heat to try to break through a very stubborn plateau, in addition to my pulley hanging at night (see my previous posts if interested), so all the PE work could have contributed to a better flaccid hang. I also trimmed my pubes in between the pics which could improve the visual impression of size in the "after" picture. It also looks like I may have started the ruler 1/8" higher on the "after" pic, so subtract that out if you want to be a stickler. You'll just have to trust me that the two photos are representative of an accurate before and after.
