What Pressure For Girth Gains?

Hi all,

I know this has probably been discussed on many occasions. But since I have been pumping and checking in regularly on TP, I have seen a lot of talk about pumping at 4-5 hg, maybe 6hg even and explicitly talk about avoiding higher pressures than that. Although I have also seen a lot of threads on here whereby guys talk about pumping at higher pressures.

However, something caught my eye this afternoon on Reddit /gettingbigger whereby a user was saying he had been pumping consistently for a long time but has not seen any girth gains. The responses were overwhelmingly recommending to him that he pump at 10-12 hg to get girth gains.

I know there is a difference between the following:

- pumping for EQ versus pumping for girth gains and,
- incremental pumping versus a single, longer duration pump session.

I know for a fact that I would see endema at 10-12 hg after about 15-20 min I reckon. At the moment for instance, I can pump at about 5 hg for 30+ minutes and not get heavy endema. But to be honest, I haven’t really seen huge girth gains either although I know it can be difficult to gain girth.

It would just be interesting to get an idea of what the latest opinion is on TP on pumping at 4-6hg versus say 10-12 hg.

I analyzed, reviewed, and shared an article here regarding the timeframes needed to increase circumference with a vacuum pump, taken from Reddit. Check out my post in the Italian section.

In my experience higher pressure/times = more edema I’ve put more of an emphasis on clamping,

With a little bit of pumping the last few months and it seems to be working.

I don’t have a measurement for my starting girth. It never occurred to me at the time. But I still have my first tube, which was 1.75" ID. I remember I could flap my erect penis around inside it like a clapper in a bell. I’m guessing somewhere around 5" to maybe 5.25".

After several years of pumping at 3 to 5" Hg, my cemented girth is a hair over 6", and occasionally 6.3" temporarily, if EQ is good enough.

The "pump it harder" guys might consider I wasted a lot of time doing it my way, but I never managed to injure myself with the pump, either.

I water pumped consistently for 20 months at about 5 inHG for 20-30 minutes uninterrupted. Gains were steady for about a year and then leveled off.

For the last 6-8 weeks I’ve worked my way up to water pumping at 10 -12 inHG for 5 minute sets with 2-3 minute breaks. I stop when I start to notice too much edema which is usually between 15-20 minutes. It’s early but I’ve been seeing girth gains with this routine.

Higher pressures definitely carry more risk but shorter sets make that manageable for me. So far, I haven’t experienced any problems. Some guys blister quickly at those pressures. My only bad experience with higher pressure was when I first started with a bathmate and would do 15 minutes straight at max pressure (~13inHG). My EQ sucked but I had no long term effects.

I began pumping for 20 minutes at 5 hg twice a day. After six months I added a 45minute session ar 4 hg. After five years I had gained over 3/4” of girth. I subsequently reduced time pumping and gained another 1/4”

There is published data that a sweet spot of pressure for growth is between about 11 and 14 inHg. This is a range that is beyond the physiologic pressure of a natural erection (and therefore expands the girth-limiting tunica beyond a normal erection) and pressures that have, at least in laboratory animals, have resulted in biopsy-proven fibrosis of the internal erectile tissues.

There is other data that points to set times of 5 minutes, with a 2 minute break, for a total of 10-20 minutes of time under vacuum, to be effective at producing gains, again, at least in lab animals.

So while it is still a crapshoot as to what is ideal for humans (at least in terms of best practices) I’ve used that as a guide. Because I also do a lot of clamping I can’t say if it is solely effective, but I have made good girth gains with a target of 11-12 inHg for intervals of 1-5 minutes for a total of 10-20 minutes per session.

Over time I have gotten much less superficial edema, but it is a factor as to how long I’m in the tube on any given day. I do think that efficient gains require riding that line, though.

Of course you have to work your way up to that pressure, but in terms of efficiency of training, going intense for a couple of 5 minute sets seems like a worthy goal assuming the same results with lower pressure over longer sessions.

I should also mention that this is my training target. If I’m doing pre-sex prep I go much lower, like 5-7 inHg for 10 minutes. I get some transient extra girth without superficial edema and no loss of sensitivity or EQ.

Tenaciousd always knows what’s up. I’ve seen those same animal studies and it seems that 300 mmHG (12 inHG) is the point of diminishing returns. Injury risk is dramatically higher beyond 300 mmHG and becomes very likely approaching 400 mmHG

For the past 4 weeks.i have pumped twice a day at 10hg which is the pressure recommended after my first pshot.

Ive since moved from 1.75 to 2 inch tube. But now I do 1 set in the 2 inch and then the rest in my new 2.125 tube.

Fwiw

Hi, i think 5-7 Hg is the best. 10 Hg is the max safe i think, and not for a long time. Volume session work better. For exemple twice a day after 12 week of practice with one. For 10-25 minutes

IME Higher pressure for shorter time has had better effects. More than 10 inHg and edema onset is much more rapid.

How do you know the max pressure was 13hg since as we know there’s no gauge?

I ask as I’m trying to work out what kind of pressure I’m at when sucking on the hose of a normal tube. Any ideas what that would be?

Incidentally my EQ has been it’s usual quality since my water experiment.

I don’t have a lot of experience but from what I have seen so far, with a 3 sets of 5 minute protocol with a 2 minute rest in between, progression of expansion begins at one notch of pressure below 5in/hg. With no edema what so ever.

Not sure about higher pressures and not sure what is required after a plateau is reached.
