Where Best to Inject?

Postby Stew52 » Sat Apr 21, 2018 2:13 pm

I know this is an old standard question, but here's a twist and question: which way does the blood flow in the cavernosa? Up from the base or down from the head?? (or maybe fed at multiple pints and across"?) It would seem to get the best distribution and chemical contact, you would want the injection at the beginning of the blood's journey up or down so it made the most contact in the cavernosa and had the most effective reaction for the least dose.

And an observation. In testing for a possible mix allergy (see other thread), I injected Tri-Mix on one side which yeided a bad red swollen allergic reaction but Caverject on the other side and it was normal. I did the usual massage to spread the mix. (Unfortunately the member was so pissed off from the allergic reaction that he did not come to attention.) But the notable issue is that the migration from side-to-side was minmal. My urologist just shrugged and looked perplexed. And at one point In experimenting earlier with Caverject dosing, I was going to 2x20 +/- mgs with one on each side. And IMO the erection was stiffer than just in one side. No I am not a jabbing masochist, just experimenting to optimize it for me.

Comments??

interesting topic. So sorry to hear of your allergy! For almost 5 years I've been injecting (just plain Alprostadil at max concentration). I started doing 8 units ( as marked off on the syringe but through the years have had to steadily increase to get the same excellent results. Was up to 18 units, then just got a fresh order that works for me at 12 (solo JO) and 14 (sex with wife).

I've never experimented with location to inject like you have, pretty much sticking (and i do mean "sticking" lol) to the guidelines provided: stay close to the cock base, maybe up the shaft a bit to maybe 2" a few times. Once did the 1/2 dose on each side and again, the result was much the same, which is to say awesome! Over the years, and starting as a burnout on Viagra the Cialis, my injections have almost never let me down. As for the sticking the needle part, I have to confess I might be one of those guys who just love it! Most likely its the anticipation just being sure that it WILL work and I will have a nice hard, long lasting and pleasurable erect penis in a matter of minutes. Placed right the needle slides in so easily it is almost like my cavernosa is sucking it in!

Enjoy your experiments and keep us informed. But for utility it seems to me that the normal standard works best and most of all so consistently. As was discussed in a recent post I'm one of those guys who once in a while will take a shot, a small one, and just play. Play with myself just for the sheer pleasure of getting then having an erection. Hope it works out for you and thanks again for the scientific report.

I find it doesn't matter if it's at the base or at the top (near the rim of the head). I get solid reaction with injecting on either side as well. However, I do notice a better reaction when injecting closer to the 10-11:00 position as opposed to the 3-9:00.

Bump. A scant bit of research (Wiki & elsewhere) seems to indicate there is a sizable artery down the middle area of each cavernosa that floods the cavernosa when stimulated and the inlet valve opens up. I'll disc with URI next appointment since they know the plumbing, but I assume the artery feeds the cavernosa down its length so injecting at base or nearer the head may not matter depending on where/how the veins drain it.

But,

1. I did not see cross ties between the two cavernosa. Guidance says to massage in to get it distributed to the other side?? How does that happen if they do not communicate well? In my evaluating a possible allergic reaction to Tri-Mix, the injecting the left with PGE was inflamed, but injecting the right with 20 mcg Caverject was normal and not inflamed. Communication?? Hmmmm.

2. At what point in developing an erection is it best to inject? Initially, before any engorgement so the mix is washed around the cavernosa? Or when it is partially or more completely engorged (via pills/foreplay or pumping)? The latter gives a much better deeper broader target for me especially with a 1/2" needle. And it is better to avoid veins. My one good haematoma was hurried and flaccid and I hit a big one that was hard to see flaccid. The former seems like it might be more effective but the latter safer.

3. Along these lines, it seems that hitting the cavernosal artery at the base may distribute it better. Ac=voiding it is just hit-and-miss anyway.

Thoughts? Experience? Thanks.

You don't want to hit an artery. Keep it simple>>>I like to use 1/2" needle for adequate penetration. For me the critical location is NOT base or top, but orientation from horizontal. I use 10-11:00 and 1-2:00 vs 3:00/9:00. I have had equal results from the RIM to the BASE>>>no difference there. BTW, Injecting on one side will penetrate the other side...trust me.

Trust me, completely flacid, a 1/2" needle might go all the way through and out the other side. That's why I usually hit it after mild play and moderate engorgement. Agree on mid-placement I try to hit 2-4 or 8-10.

But if you look at the cross-seciton diagram, there is a small INTERNAL artery that runs down the middle of each cavernosa that feeds it. I have no idea how you will miss that every time going blind unless you have x-ray eyes. I imagine hitting this causes some damage and internal cavernosa bleeds? It's hard enough to miss exterior veins all the time.

So many unanswered questions for n]my next URI appt after the allergy tests.

Regarding the distribution of the medicine and the communication between the two sides: I use only 3-5 units of a very potent mix of 40/2/30 Trimix which is literally a drop and have no problem of distribution with minimal massaging after.

I used Autoject hundreds of times which shoots the needle into the penis pretty fast so I have no control to hit that internal artery or not, but never had problems.

I’d say it would be better to have semi erection when injected and just alternate the locations as much as possible. I myself cannot even get a tiny erection and use 1/2 inch meddle set at 5/16 depth on the Autoject.

All the best!

I can get a ~90% erection without drugs but not sufficient for good penetration and good mutual sex. I guarantee you if you use a pump - which I do now regularly to improve blood flow, work the valves, stretch and expand the member, remove fibrosis and adhesion's of injury or old age, and work out the "muscle" - you would get something sizable to inject into. Completely flaccid I would use a 5/16" needle at 1 1/8" dia.. Well engorged at 2 1/2" dia a 1/2" works best.

I'll mostly agree with rahod1 as to placement. I use the 5/16 needle and bury it deep. I inject completely flaccid as that's the only option I have. Without an injection I have NO erection. Pumping it up with a VED would just result in my trying to hit a rapidly moving target as it quickly deflates. I don't think I want to try it pumped up with a tight constriction ring applied. I agree that pumping with a VED is good therapy.

With me injecting one side effects both sides equally. I don't know how the blood flow actually works internally but both sides are effected equally with one shot.

I don't think injecting both sides each time is a good idea as it would double the chance of scarring from the stick itself.
