Michael Lim runs a stem-cell clinic and biotechnology laboratory in Kuala Lumpur. The distinction he insists on is the whole point of his work: he is not transplanting stem cells into you. He is switching the ones you already have back on.
His team isolates a protein from umbilical cord — something every one of us was exposed to as a baby, which is part of why the body accepts it readily — and introduces it so that it passes through the cell wall. Your own mesenchymal stem cells then reactivate, begin replicating, and travel to wherever the body has been signalling for help.
The day before treatment there is a pre-booster, deliberately quietening the routine background noise so that the genuinely persistent problems call louder and get found first. Patients tend to notice the fastest-repairing tissues first: skin, gut, cornea, liver. His favourite tell is that after the liver improves, a glass of wine hits much harder than it used to.
He started in Singapore and moved the operation to Malaysia in 2014, when research and development costs made that the sensible place to build. Over twelve years he has treated more than a thousand people and followed them up throughout. Two of his long-term patients died recently at 100 and 102. He does not market: the practice grew by word of mouth. And he was, as he puts it, his own first guinea pig.
We had met him four months earlier, at the Longevity Summit in Dublin, and that is where he told the story of how the work began. In 2012 he turned away from the trend of the day — culturing stem cells to reactivate your own — because the results were unstable. What he went looking for instead was a group of proteins that could be taken from umbilical cord, and a way to get them through the cell wall. The technology his company built around that is called CEXCI. The clinics are mostly in Malaysia, with Thailand as well, and the head office in Singapore.
One thing to hold on to while reading him. Everything on this page about what the treatment does is his own account of what he and his patients have seen, followed up over years in his own clinic. It is not published trial data, and he does not claim it is: his own words are that they are walking the talk, and waiting for time to prove it.

Of all the interviews on the quest, this is the one with something personal riding on it. Marek was going to have the treatment the following day, and it was Aleksander who sat down to interview the man who would perform it. He didn’t open with a question about the science. He opened by saying that this felt like a big thing his father was about to do, and asking Michael to assure him it was safe.
“I just want you to assure me he’s safe.” — “He’s safe. And your father’s not a guinea pig. The first guinea pig was myself.”

“Our definition of longevity is health span. We don’t know life span yet — we’re focused on keeping you healthy inside your health span, and extending the time.”
Michael Lim · Kuala LumpurYour father’s not a guinea pig. We’ve done over a thousand, and we’ve followed up with our patients for twelve years. The first guinea pig was myself.
Michael LimWe take a protein your body has used before, from the umbilical cord, and add it to your system — it kickstarts your own stem cells to work healthily.
Michael LimThe stem cell grows its own stem cell. Then they go and home in on the places that need help.
Michael LimWe are slowly slowing down the dynamic aging process. That’s all.
Michael LimWe are actually walking the talk now. So we are just waiting for the time to prove that longevity works.
Michael Lim · DublinEverything that comes free is not being appreciated at the beginning, at your age. You gotta drink lots of water. You gotta have enough sleep. You gotta reduce your stress.
Michael Lim · Dublin, to AlekFrom Aleksander’s conversation with Michael in Kuala Lumpur — what the treatment actually does, what you notice first, and the exchange about what longevity is really for.
Not a transplant. A protein isolated from umbilical cord passes through the cell wall, and the body’s own mesenchymal stem cells reactivate — replicating, then travelling to wherever the body has been signalling for repair.
“It will kickstart all your stem cells to get activated to work healthily.”
Kuala Lumpur · from the interviewThe fastest-repairing tissues report back soonest: skin, gut, taste, breathing, stamina, the cornea — and the liver, which produces his favourite piece of evidence, since a repaired liver makes a single glass of wine land far harder than before.
“Your eyes start to glow, because corneal regeneration improves.”
Kuala Lumpur · from the interviewAlek pushed past the procedure to the point of it — that the goal isn’t simply more years, but compressing the decline at the end. Michael agreed immediately; it is how he defines his own work.
“You’re not dying for twenty years. You’re dying for a little period of time — and living, before that.”
Kuala Lumpur · from the interviewThe video interview is coming. Recorded interviews go live after the launch of the film & series Live Beyond.
Selected passages from two conversations with Michael Lim — Aleksander Piotrowski’s, in Kuala Lumpur in October 2023, the day before Marek’s treatment, and an earlier one at the Longevity Summit in Dublin in August 2023. Cleaned of hesitation only.
Aleksander Piotrowski“I feel like it’s a big thing that my father is doing now. And I just want you to assure me he’s safe.”
Michael Lim“He’s safe. We’re not too worried about safety, for a very simple reason: we’ve been doing this twelve years. We’ve treated over a thousand clients, and we follow up with our patients. When we isolate the protein we have our own technology to prevent even allergy, so when it goes into the body it’s very receptive. And this protein — you were exposed to it before, when you were a baby. We take it from the umbilical cord. Your father’s not a guinea pig. The first guinea pig was myself.”
Michael Lim“First we do a consultation to see your body and how it functions, and any problems — hypertension, diabetes, whatever. Then we do a pre-booster, a kind of detox, so that a lot of the signals asking for help will be quietened. Then tomorrow, the more persistent problems call for help more — and when we activate it, it goes to those places to help your body.”
Aleksander Piotrowski“Please explain to me what will actually be happening in my father’s body after the whole treatment.”
Michael Lim“Once we put in the proteins, they’re absorbed into the cell — the cell walls have what we call communication walls, and we have our own way to make sure the door opens. Then your father’s stem cells receive the proteins, and it kickstarts them to rejuvenate. Not only rejuvenate, but increase their ability to grow their own. The mesenchymal stem cells grow on their own, and then they go and home in on the places he needs help.”
Michael Lim“The face and the skin are the first areas you see the benefit — skin is very sensitive to stem cell rejuvenation. Then the intestine: constipation improves, IBS improves. Your taste buds improve, your breathing improves, then your stamina. Your eyes start to glow, because corneal regeneration improves. It always starts with the tissues with the highest ability to repair — the cornea, the liver. And after the liver improves, the first thing your father will realise is that a glass of wine or two will make him feel tipsy very fast.”
Michael Lim“We started in Singapore — we were the pioneers there. Around 2014 there was a lot of migration of good companies from Singapore to Malaysia, and the operating cost here was much cheaper, so I had the opportunity to get the equipment at a better price. That’s why I gave birth to all this in Malaysia, so the cost of R&D isn’t so high. R&D is a very expensive endeavour.”
Aleksander Piotrowski“How do we improve the cost of it, so it’s actually less expensive?”
Michael Lim“Volume. Our treatment is not a cheap treatment — the age that usually does it is around forty to sixty. We’ve treated people in their eighties and nineties. Two of our patients, who were with us for the last eight or nine years, just passed on at 102 and at 100. We’re quite proud of them. We’re also doing animal studies and progressing to clinical trials. We don’t market ourselves — it’s all word of mouth.”
Michael Lim“It’s an ongoing process. We are slowly slowing down the dynamic aging process. That’s all. We don’t think too far away — for us, our definition of longevity is health span. We don’t know life span yet. The only two people who could tell you are 102 and 100 years old.”
Aleksander Piotrowski“I feel like our main goal should be to shorten the death period. You should live as long as you can in a healthy state — so you’re not dying for twenty years. You’re dying for a little period of time, and you’re living, before that.”
Michael Lim“Correct.”
And from Dublin, four months earlier — the Longevity Summit, August 2023, where we met him first. What follows is his own account of his own clinic’s experience. It is not published trial data, and the figures in it are his.
Michael Lim“It all started in the year 2012 when I accidentally thought, maybe I’m in a different direction from stem cells. Because at that time, I think the trend was using stem cell culture as a way to actually activate your stem cells. But I found that there was a lot of instability. No danger, but a lot of instability in the results. So I ventured even deeper. I found that there’s a group of proteins that we can actually get from the umbilical cord. And our technology, we name it CEXCI… It’s actually a special technology to see how the cell wall can behave, because not all two cells can communicate very well because it’s of two different DNA. So how we successfully help is we help your stem cells to open the cell wall door. Therefore, the proteins can go in and rejuvenate your stem cells… to start the chain reaction of stem cell renewal again.”
Michael Lim“You will see in the first couple of months, you will see your eyes will start to glow. Your skin will start to glow, be more radiant. And you won’t age. So the best result is seen after 2 years because you’re able to compare with your peers, and you found that: hey, I didn’t age. And then your wrinkles will improve as well… Your taste buds improve, so when you’re eating your food, you kind of taste better. Your memory will improve greatly, because my memory was very bad before. And of course, it helps your hearing… We’ve got even people who improve the breathing. The lung capacity improves. And muscle strength increase by at least 40%.”
Michael Lim“Like my father, who did the treatment 10 years ago — he was a diabetic since 32 years old, so we did for him when he was 70… He has stroke, cerebrovascular accident 7 times, with diabetes as well. So you wouldn’t think that he would live anything longer than 72. He went all the way to 81.”
Michael Lim“We’ve done, on compassionate grounds, for people as young as children as young as 3 years old to as old as 99 years old. So we haven’t yet reached anyone with centurion, but we are getting there. So we are still monitoring them. All of us are doing it for the purpose of anti-aging and wellness.”
Michael Lim“We have done about 1,000 over patients, or clients… We have not seen any. Maybe on the first day of the treatment you may feel a little bit tired. I mean, you clock an earlier hour to sleep, like a child, at maybe 10:30 PM, rather than your usual 12 AM… So you will feel a little bit of warmness in your blood, I mean, in your body, but there is no fever when you check.”
Michael Lim“We don’t believe that everyone will have all the solutions, so we actually know that there are many layers and there are many segments that we need to explore. That’s why I came to Longevity Summit — to see, I’m looking at all the experts with all their different directions, and it gives me a big global perspective and also on the whole topic of longevity, how vast it is.”
Michael Lim“Live healthy. That’s number one. Everything that comes free is not being appreciated at the beginning, at your age. You gotta drink lots of water. You gotta have enough sleep, right? You gotta reduce your stress, right? So these are the first few key free things that you can do. And over the years, if you don’t take care, you’re gonna need money to support that… And of course, appreciate life.”
Michael Lim“Budget for your children’s education or property that you need to grow, budget for your retirement… And also budget for caregiving. Because everybody is going to reach a stage where they cannot take care of themself. That is not an option. It is a natural process that you reach a stage that you cannot walk, so someone needs to take care of you.”
Michael Lim“I wish you all the very best in expansion, and I will support you all in any way I can. I think what you’re doing here is very wonderful, and I think humankind will benefit from this in the many, many decades to come. And this would mark, I guess, the history of the longevity. It could be the first phase, but you’re doing all the very, very good works to bring the right people here into the network.”
