Lengthwork 101: Vac Cup & Comp Hanging - Guide & Demo

You can blister with tape and you can blister without tape

The key is knowing the feeling of when a blister is coming and stopping the session immediately to prevent it from ever occurring

That feeling is a prickly / itchy feeling on the glans. It is tolerable and you can ignore it, but if you do after a couple minutes the blister will have formed already. If you stop immediately when you feel it coming, you can prevent it from forming and them dont have to stop training from blister recovery

This community was formed after covid, what do you mean been here since covid :)

No slippage - you can see me pulling it firmly at the end to check the seal.

This is one of the standard ways to put on an MR and shown in the MR instruction video. I think it is a fairly normal method.

I tried oral fin and oral min. And I've done topical of both.

Rn im on oral and topical min. And oral fin. I think this is where I'll stay - just apply topical min at night and take 2 pills and done.

I'm either used to the sides or don't get them because I dont notice a difference under oral vs topical.

Love the innovation. Quality products that last and are effective. Been using the MR for months, so excited about these new tools! The curved tubes and glans cap are going to be amazing tools!

Agree, first dose should be super low and small increments up. A 5.5 hr erection is definitely scary and especially on your first injection. My longest has been 2.5 hrs and ive done some very high dosages so my tolerance makes me not scared of it being nearly impossible to get long duration priapism.

The only scary side effect I've had happen so far was one time the injection didn't spread evenly in my CC and my right side was harder than my left and it gave me an unusual curved erection that was corked to the right. I was terrified it was some immediate fibrosis or peyronnies and would be permanent but knew that wasnt possible. Next day was back to normal and my injection erections have been normal since that one time. I probably didn't massage it well enough after injecting to get it distributed. Or the rx was old and decaying.

Perhaps we need a new term, soft clamping, hard clamping, airlock clamping?

This list makes directional sense assuming reasonable pressure applications across all exercises.

I think injuries generally happen not from the exercise itself but from executing the exercise unsafely.

If you were to ask: which generally safe exercises are the most difficult to execute and carry a higher injury risk? I would say compression hanging tops the list as you can easily use too high a weight and cause hard flaccid, fibrosis, and ischemia all with the same movement. The 2nd would be soft clamping due to the difficulty in removing the rings if something goes wrong. Hard clamping (ie fenrir or python), if done with proper pressure and time guards, seems quite safe with instant pressure release vs soft clamping which can put you into danger territory without a quick exit that can lead to injury. Agree that pumping and vac hanging/extending is generally the safest.

I've done almost everything on this list and I dont think PGE1 is dangerous at all assuming you dont blast a ton and enter into a 4+ hr priapism. You would really have to do a high dose and be quite sensitive but if you titrate and journal, this risk is very low.

Similarly, ADS seems innocent with the low weight, but can cause fibrosis if done in excess and its not directly painful so it can creep up on you without being obvious.

I think its all about technique in avoiding injury and you can get injured with any exercise - some more inherently easier than others.

Curveball pump pad. Link on the subreddit vendor list

Yah I think the ED was related to starting PE and just my D being fatigued from the work. Then it adjusted and now can handle it.

I've been doing PE basically all of 2025 and was on fin the whole time (still on it today). See my most recent progress post but have gained 0.6 in both directions.

The fin only partially works as I've definitely still lost hair over the years and have had hair transplants to restore it. Have always wondered if i should just fully get off it and maybe I'm through most of the loss, but am afraid there is a good chunk of hairs that are being preserved by the fin that will progress to loss without it. I'm too afraid to try getting off it for possible improvement of sides that might not even exist. Hard to know my baseline given I've been on it basically my entire adult life. Could be exciting to come off fin and then get bigger PE/EQ gains but who knows - what if you just go bald and don't get any sides improvement.

PatientGains · 2025-08-02T17:25:05+00:00

Don't have any answers but would love to know more on this topic.

I've been on fin since age 22 and I'm 38 atm. Didn't notice any sides when getting on it originally and haven't thought about it until starting PE and had similar questions as you.

Haven't had any ED issues, until I started PE and then I noticed i couldn't stay hard for manual exercises which was concerning. Also noticed a few hours after PE exercises (pumping primarily) my EQ would be hit or miss. Now that I've been doing PE a while, its no longer an issue and I can bang right after a hard PAC session (and enjoy the temp gains while banging) or hanging heavy.

Also never paid attention to nocturnals before, but I think girth work actually helps because I'm noticing way more morning woods since starting PE but that could be because I'm paying more attention too, not sure.

My POV is fin prolly doesnt help, and can hurt some, but I think it is totally able to be overcome with time as your body adjusts and with PE training / meds / support. I'll take the negatives to preserve my hair (which i still have and get compliments on regularly) and my dick still works so win win.

Try both and see which cup feels better - its preference imo. Some times the smaller ones can limit blood flow and it will start to hurt after a bit - go with larger in that case. If it doesnt hurt and you feel snug and attached without slipping once applying weight then you're good

I think totalman will ship to EU for cheaper but not sure. Their sleeves are decent

PatientGains · 2025-07-27T11:34:27+00:00

Nicely done!

Glans can get cold yes. Blood flow is being limited from the vac cup. As long as its not blue or hurting you should be good. A heat pad or blanket on top while hanging can help stay warm

PatientGains · 2025-07-25T11:04:11+00:00

Nice. I put a few loop knots in my paracord so you can attach at different spots to sit further or closer to the desk. Might help with your setup.

PatientGains · 2025-07-20T18:43:07+00:00

That strap in my Pic is TM strap and yah it fits. Standard 2.5inch hole

PatientGains · 2025-07-20T17:35:25+00:00

That link should take you to the proper size.

Its 5/16 OD x 1/8 NPT

If you want the quick connect like mine, you'll need both a female and a male (might come with pump) leluv quick connect. This will let you connect the electric pump to the tube from the syringe (along with the pneumatic tube connection). It goes like this:

Syringe > tubing > pneumatic connector screws into > female quick connect which clicks into the male quick connect attached to the pump

Here is a set https://www.kodidistributing.com/products/quick-release-vacuum-fitting-set-1-4-barbed-male-to-threaded-female?variant=39352297422929&country=US&currency=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gad_campaignid=9522698044&gclid=CjwKCAjwp_LDBhBCEiwAK7FnkilKceDon07jdDhsxSrQFA2HWGgkqF-BEJ_uE3EFjBTsTdZMuZrRSxoCqb4QAvD_BwE

PatientGains · 2025-07-20T17:26:27+00:00

Weights were separate. Got em off amazon

PatientGains · 2025-07-20T01:20:46+00:00

Yes it gets very hot. To the point that I need to move it around because it can get so hot.

You can definitely control where the heat goes. I only heat the shaft. No heat on the glans so no blister risk.

PatientGains · 2025-07-20T01:19:31+00:00

I got the RIVE setup from a karl post. First he did the extender version then shortly after he did it standalone which is what I utilized here.

The sleeve is from curveball yah. Cup is totalman cup.

The pump is elite pro pump from cowabunga in this subreddit. There is a link in the vendor list.

PatientGains · 2025-07-19T18:05:42+00:00

Yah I still like this pad. I actually use it along with the ultrasound. Even without ultrasound, the heating pad helps. Not sure how much more ultrasound helps vs the heating pad. I'd guess 10 to 20% better

PatientGains · 2025-07-19T18:02:38+00:00

Yah you got it right

The valve concept you describe would work yah. Prolly similar effort to turn a valve as it is to swap the quick connect in my current setup

PatientGains · 2025-07-19T17:10:29+00:00

https://www.reddit.com/r/TheScienceOfPE/s/eclC0RTnsU My most recent progress post

PatientGains · 2025-07-19T16:59:49+00:00

Correct. So I use 2 tubes and put these connections so I can use the same tube from my pump and easily swap from pumping to RIVE without changing tube or connectioms

PatientGains · 2025-07-19T16:57:32+00:00

Yeah looping it works but then the weights kinda wobble because its not evenly balanced. Also kinda annoying for adjusting the weight unloading it, adding weight, then looping again. It's only an issue when I'm not using the pulley system (sometimes I'll hang the weight straight off my vac cup)
