Master your bell.
Do it right.
A vacuum bell only works with the right protocol, and the box doesn't include one. The cited protocol, from first session to overnight.
The two mechanisms behind the bell, and the dose that lifts a sternum.
Why most people use it wrong, and the framework that fixes it.
You bought the device.
Now you're guessing.
The manufacturer's leaflet tells you how the device works mechanically. It tells you nothing about how to get results, and that gap is where months of progress quietly disappear.
The device isn't the variable.
The protocol is.
Get the suction calibration, the dose, the ramp and the plateau strategy right, and the same bell that did "nothing" for a year starts producing measurable lift. This guide is that protocol, every claim referenced.
Backed by the research,
not just my opinion.

started at 19 with a chest i couldnt look at in the mirror. went with the excavatum course cus everyone kept telling me nothing but surgery works and i didnt buy it. 5 months of doing the work most days and my chest sits noticeably flatter now - the surgeon who told me wait and see at 17 wouldnt recognise it. only regret is i didnt start the day i turned 17

gaining weight was the bit nobody would explain to me. 3 months on the nutrition plan, 5kg up, and the same chest reads completely different at that weight
Felix PE 28

It works. the suction takes getting used to and i gave myself a bit of skin bruising the first fortnight, until i dropped the pressure back to what the guide actually says. my fault not theirs
Marc-Antoine PE 33
Vacuum Bell Quebec, Canada 🇨🇦
- ★★★★★
honest review. 5 months of consistent bell use and my depth has barely moved. im 35 and my chest wall is stiff, which the guide does warn about upfront. the posture and breathing side genuinely helped and i dont regret the money, but i wouldnt tell someone my age to expect what the teenagers are getting

dip and flare at the same time. THE FLARE WENT FIRST, which nobody warned me would happen, and that alone changed my whole silhouette
Bruno Salgado PE + Rib Flare 30

- ★★★★★
brace did its job on the flare. what i actually wanted was how to run it alongside the vacuum bell work in the same week. asked and got a proper answer same day, but that should be in the material, not something you have to know to ask for

the breathing protocol alone changed how i feel day to day. didnt realise how shallow i was breathing until i fixed it. the rib flare correction kind of followed on its own

My son is 15 and was getting self-conscious at the pool. The carinatum brace and the fortnightly check-ins are what kept him consistent. Six months and the ridge has visibly dropped.

what sold me is that every claim links to a study. only place online that treats pectus like an actual training problem instead of selling a miracle

Everyone i asked just told me to do more core. turns out i was breathing into my neck this whole time. learning to actually use my diaphragm was the entire fix
Georgia Rib Flare 24

- ★★★★★
started out flat on my back every night checking whether my ribs still stuck up, they always did. got the rib flare program and actually did the breathing side properly this time instead of just the exercises. four months later i lie down and theyre flat - i still check out of habit and still cant quite believe it

material's good and i have no issue with the science. my honest gripe is the early modules cover the same ground as the free blog posts, which id already read before buying. the later phases are where the real value sits. wouldve paid the same to skip straight to those

Wore it 8 hrs a night for 5 months. the ridge is basically gone. im 16 so i got lucky on timing, but you still have to wear it every single night. beat the operation they were lining us up for

The wear-schedule chapter is honestly the whole product. everywhere else online just goes "wear a brace" and leaves you to figure out the rest

spent two years hiding the ridge under hoodies before i actually did anything about it. what changed it was the carinatum program - building the chest and back around the ridge instead of just bracing and hoping. six months in and it reads flat enough that the hoodies are gone

solid guide and the pressure numbers are genuinely useful. half a star off cus im 28 and the whole thing is pitched at teenagers. an adult section, where the timelines are honestly different, wouldve been worth a lot to me

Two months in and I've put on 3.2 kg of muscle. My chest doesn't cave the way it used to when I'm standing relaxed, and that alone was worth it.
Milo PE 25

Nine months, 5.7 kg of muscle on, and 0.9 cm off the depth of my chest. I am 32. I had been told the window for fixing this closed at 18.

Five months, 4 kg up. The dip is still there if I go looking for it, but nobody else finds it anymore.
Lars PE + Rib Flare 25

I am 52 and carried both a ridge and a dip my whole life. Dropped 9 kg in five months and my chest finally reads as one shape instead of two.
Greg Henderson PC + PE 52

Three months, 5 kg on, and the ridge sits lower than it ever has. At 19 I thought surgery was the only thing that would fix it.
Ethan PC 19

Nine kilos in six months. Building the muscle around the ridge did more for how it looks than the years I spent hiding it under loose shirts.

What people ask
before they begin.
The four that come up most, answered the same way I would answer them on a call.
Take the 60-second quizHow long before I see a change? +
Posture and breathing shift first - most people feel that inside the first few weeks. Visible chest change is slower. In the case log above, Milo saw his first real change at 2 months, Ian at 6, Liam at 9. The programs run 16 weeks because that is roughly how long it takes for the training to show up in the mirror.
Am I too old for this to work? +
Almost certainly not. The clients documented on this page were 22 to 32 when they started. Cartilage does stiffen with age, so progress is slower the older you are - but slower is not the same as stopped. What changes is the timeline, not whether it is worth doing.
Do I need a gym, or can I do this at home? +
Either works. Every program ships with a gym track and a no-equipment track for the same 16 weeks, so you pick the one that matches what you actually have access to. You can switch between them mid-program without losing your place.
Pectus excavatum, carinatum, rib flare - is it the same plan? +
No, and that matters. A sunken chest and a protruding chest need close to opposite work, and rib flare often rides along with both. There is a separate program for each. If you are not sure which one you have, the 60-second quiz sorts it out and points you at the right starting place.

I'm not writing this as a doctor looking at a scan. I had the sunken chest, the flared ribs, the shirt that stayed on at the pool, and nobody could tell me what actually works.
Everything on this page exists because I needed it to exist ten years ago.
I had it. I fixed it.
Now I help you do the same.
I'm Mihail Veleski. Pale, skinny, sunken chest, flared ribs, I had it all, and it wrecked my confidence. Years of consistent, non-surgical training made my deformity unnoticeable.
I founded Mr. Pectus to give people the exact path I had to find the hard way, tested on my own body first, then refined every time someone hit a wall I had not planned for.

Common questions.
Do I need to own a vacuum bell to benefit? +
It’s most useful if you have one or are about to get one, it’s a protocol for using the device. The candidate self-test and the science sections are also valuable while you decide whether the bell is right for you.
How is this different from the free advice online? +
Free advice is scattered and often contradictory. This is one coherent, cited protocol (40+ studies reviewed, a clear framework, and a step-by-step ramp) so you stop stitching together conflicting forum posts.
Will it work for my bell brand? +
Yes. The protocol (fit, suction calibration, dose, ramp and plateau strategy) applies to any vacuum bell. It’s about how you use the device, not which one you own.
I’ve plateaued, will this help? +
Specifically, yes. There’s a dedicated section on why progress stalls and the exact adjustments, suction progression, dose, supporting work, that restart it.
Is it really cited? +
Yes, 420+ references throughout, mapped to claims so you can check the evidence yourself. This isn’t opinion; it’s the literature organised into a usable protocol.
How many hours a day should I be using the bell? +
That’s exactly what the dosing framework answers, session length, sessions per day and suction level, phased from your first week through the long-term ramp. More is not automatically better; the guide shows you the dose that produces change without bruising you out of consistency.
Is vacuum bell therapy safe? What about skin marks? +
Used within sensible pressure and time limits it has a good safety record in the literature, and temporary redness or mild bruising is the most common side effect. The guide covers safety limits, contraindications and skin care explicitly, and tells you when a symptom means stop and see a doctor.
How long until the dip visibly lifts? +
The in-session lift you see under the bell is temporary at first, that’s normal. Lasting change builds over months of consistent dosing; the guide sets realistic phase-by-phase expectations so you don’t quit at week three for the wrong reason.
Am I too old for a vacuum bell? +
Adults respond, more slowly than teens, and the guide is honest about the difference. The candidate self-test weighs your age, chest flexibility and dip shape so you know what to expect before you commit months.
I don't own a bell yet, which one should I get? +
The buying section walks through what actually matters, fit against your chest shape above all. A bell that seals properly beats any brand claim; that’s also why the custom-fitted bell exists for chests that off-the-shelf sizes don’t seal on.
How is this different from the PE course? +
This guide is device mastery: everything about using the bell optimally. The PE course is the full correction system (breathing, training, posture, assessment) with the bell as one module. If the bell is your main tool, start here; if you want the whole method, the course is the bigger step.
How do I get access after checkout? +
Instantly. Checkout takes a minute and the link to everything lands in your inbox right after, read it on your phone, tablet or laptop. Lifetime access, free updates, nothing to ship.
What if it’s not for me? +
You're covered by a 30-day, no-questions-asked, 100% money-back guarantee. If it isn't what was described, email me for a full refund.
