How long can you pump?

In one session how long can you conceivably pump before you risk irreparable tissue death due to deoxygenation. Because I honestly feel like I could do 8 HG all day. No breaks. Any thoughts?

Testing has been done for pumping overnight at 2 to 3 HG safely. This was monitored the entire time.

At the pressures you’re talking about, unmonitored, I certainly wouldn’t make any bets.

Circulating blood provides a constant internal oxygen supply.

The problems you face with extended pumping are excessive bloating from accumulating lymph fluid and red spots and or bruising from broken capillaries.

I think the results from too long a pumping session are just not aesthetically pleasing.

i have never stayd on the tube for more than 30minutes at a time and this at 2-5hg.

But there a lot of hardcore pumpers right here that probably can stay on the tube for 1 hour or more.

I am in the tube about 30 mins at 5-6hg no problem. However if i go much beyond that i get red spots on the bottom of my shaft. I have been thinking about why i get them at the bottom and not the top. The only thing i can figure is when i am warming up before going into the tube i used a rice sock for about 10 mins which i put on the top of my dick 90% of the time and only a small amount of time underneath. I wonder if it being more warmed up up top helps prevent spots there. The only thing that gives me pause on my hypothesis is that once in the tube i have an electric blanket wrapped around the tube and the whole thing is HOT. you would think after a few minutes of me cooking my dick it would be plenty warm but who knows.

I know there’s exceptions, but if you’re at the point where you’re pumping at 8hg all day I feel like a decon break would do more for you. Then again, I’m also not into the whole inflated look so to each their own.

Do you have any links pertaining to this? Sounds interesting

I do not. My apologies.

I’ve never done all day out of fear of risks to my health, like tissue death, and disinterest. But I haven’t gotten results in a while, so I think I should up the time. Extenders work based on wearing them 8 hours a day, the pump is similar in many ways, an expander you could say.

Never went beyond 30 minutes at 5” HG, safe and conservative enough to reap just positive outcomes.

I will guess that circulation problems will happen if you use those sleeve at the base of the tube, can’t quite name those things. If too tight plus the pressure the outflow will be compromised.

From my research on the hypoxic priapism induced megalophallus threads, mostly based on surgical tourniquet procedural guidelines and a couple studies:

Irreparable tissue death is determined by occlusion x time.

For full occlusion (zero bloodflow) necrosis begins at 18 minutes and grows exponentially. For our purposes, consider 18 minutes at full occlusion to be the equivalent of irreparable tissue death (a non functioning penis). In practice, it may be 5 minutes longer than that, or 20 minutes longer than that, or more. In practice, we do not want to fuck around with that possibility, as even partial necrosis can lead to the loss of the organ.

Moving back to the principle of occlusion x time.

For 50% occlusion it would then be 36 minutes before necrosis begins.

25% occlusion would be 72 minutes.

And so on.

For pumping, the % occlusion would be determined by the pressure mostly. And my guess is that it would be very difficult to go above say 75% occlusion, even at full vacuum, unless you’re using some kind of silicone sleeve or constriction device at the base. Whereas with clamping, it can go to very near 100%, and high intensity clamping sets should never last more than about 15 minutes.

The best way to go about a high frequency / high duration / low circulation routine - is to reperfuse (i.e. refresh the blood supply) the tissue regularly for a few minutes at a time. In other words, if you want to pump all day long - then just pump for 30 minutes at a time and take 5 minute breaks, do some jelqs, stimulate some blood flow, then do the next set. The effect on the target tissues will be about the same, and you will be safeguarded from any necrosis.

In my experience there’s a cumulative effect of doing back to back sets like this - and you can only do so much in one day, or one week, before your dick says enough is enough and then it’s time for a rest.

These studies obviously don’t examine the effect of doing consecutive hypoxic conditions day after day, so it’s vital to listen to your PI’s and rest if necessary.

I routinely pump for 20 minutes at 5 hg with minimal excess edema. About once a week I pump for 45 to 60 minutes at 4 hg with the same result.

I find the rewards less then stellar if I go more then 25-30 mins straight between 4hg and 6hg. I prefer to do 20-25 min sets with some form of edging in between sets. A couple times a week I try to do a routine gprent has introduced me to called incremental pumping. Some guys are able to go longer sets with better results unfortunately I’m not one of them.

I do daily 60 min: 30min in 1,75in + 30min in 2in cylinder and everything is normal

You have to find what works best for you. Sometimes push the limit to know when to back off and what allows you to gain. Could be from air pumping, water pumping, short sets, or long sets, ect.

I use a bathmate because it uses a vacuum. I pump for an hour, maximum vacuum, in the tub and get an inch of expansion which gives me edema around my glans. It gives me gains and more loose skin(helpful because circumsised). If i pump outside the tub with the same pressure and duration, I have no fluid built up. Despite that, I’ve only gained from pumping in the tub.

Make no mistake Brother, you have one unit and one unit only. Care for it, respect it, treat it well like you would want it to treat you.

Yes we all have a desire to be notably bigger and well sized in every dimension. Getting there is a journey and is not a box of ill cooked special K, this is a journey. I have been pumping for many moons and have tried a host of interesting and some time extreme pumping. It was all pointless. You can not beat your cock into growing faster. Do it right, do it properly and your penis will reward you.

Some of the most beneficial sessions I have had were no more than an hour. I would some time divide that hour into two sessions back to back or three sessions. Either way, pump, jelq and heat keeping the pressure within reason 5HG.

We are Thunders Place, this journey is a marathon, for some of us it is a lifetime journey. Take your time brother.
