I’m 36, train six days a week, and I have no idea how old my body actually is.
This is a live document. I will add every session with Dr. Sarassawadee Suwanjinda (Dr. Petch) at Healthi Life Bangkok here, including the tests, the findings, her recommendations, and what changed.

Session 1 — The baseline
May 12, 2026
I walked into Healthi Life assuming I already knew the answer. I train six days a week, sleep well, and eat carefully. By any visible measure, I look healthy. What I didn’t know was whether my body agreed.
Session 1 was entirely diagnostic. No results yet. The goal was to build the complete picture: body composition, blood markers, biological age, gut microbiome, cancer screening, and heavy metals. The kind of snapshot a regular annual checkup never takes.
What was done
- ✓ InBody 270S body composition scan
- ✓ Full blood panel (hematology, inflammation, vascular markers)
- ✓ Urine analysis
- ✓ Gut microbiome stool test (completed at home)
- ✓ Epigenetic age test (PPSpan — 11-organ biological age)
- ✓ Cancer screening panel
- ✓ Heavy metals panel
- ✓ IV therapy — full body detox (1 hour)
InBody scan results — May 12, 2026
183cm · 36 years · Male · InBody score: 81/100
The body composition numbers were reassuring. Low visceral fat, muscle mass well within normal range, body fat at 9.9%.
The scan also showed a slight drop from the previous measurement in March 2026: weight down from 73.3 to 72.2 kg, skeletal muscle down marginally from 38.4 to 37.2 kg. Nothing alarming, but worth monitoring.
What Dr. Petch explained
The signs people often dismiss as getting older — feeling less energized, slower recovery, mental clarity that takes longer — those aren’t always aging. Sometimes they’re biological imbalances we can detect and correct early. That’s why this program exists: not to treat disease, but to make sure you never get there.
Dr. Sarassawadee Suwanjinda (Dr. Petch), MD — Healthi Life Bangkok
Dr. Petch walked me through the Elite Tier program structure. The program is built around four medical pillars: diagnostics and biomarkers, nutrition and metabolic optimization, hormonal balance, and gut microbiome and inflammation.
One thing Dr. Petch said reframed how I think about the whole system. Wearables give you lifestyle data. Regular doctors look for disease markers. Nobody connects the two.
Healthi Life sits in that gap, combining lab results, biomarkers, and wearable data into a single picture and translates it into specific, actionable guidance. Your sleep data and your blood panel are interpreted together, not in isolation.
The part that got my attention was the epigenetic age test. Not biological age as a single number, but a breakdown of 11 individual organ ages: heart, brain, kidneys, liver, lungs, and more. The test also measures the pace of aging, not just where you are now.
Dr. Petch’s own pace dropped from aging 14 months per calendar year to 8 months after she began her own protocol. The goal is to age more slowly than time passes.
Dr. Petch shared one case that stayed with me. A 30-year-old patient came in with a biological age of 48. She wasn’t in poor health by any conventional measure. She was tired, slower to recover, mentally foggier than she used to be. The kind of symptoms most people write off as normal aging.
After one year on a personalized longevity program, her biological age was tested at 30. An 18-year reversal. Dr. Petch mentioned the largest single-year improvement she has documented is 20 years. These are not estimates or projections. They are PPSpan test results, measured before and after.

Based on the full diagnostic picture, Dr. Petch will design a 90-day protocol, covering gut microbiome, biomarkers, hormonal balance, and IV therapy. Here’s what the structure looks like in practice.

How it actually went
The IV drip took an hour, and I got a foot massage while it ran. That part I did not expect. The full-body detox formulation is designed to reduce inflammation, clear heavy-metal load, and support mitochondrial function. The lab results weren’t back yet, so there was nothing to react to yet. That comes in Session 2.
The gut microbiome test I completed at home. The clinic arranged a Grab driver to collect the sample once I was done. Which is either very Bangkok or very 2026, depending on how you look at it.
What stood out was the framing Dr. Petch uses throughout. This is not a hospital. You’re not here because something is wrong. You’re here because you don’t want to wait until something is wrong to find out. That logic made sense to me before I walked in. It made more sense after.
Watch: Session 1 — Full consultation and IV therapy
Coming next: Session 2 — The results
May 27, 2026
The first lab results from Session 1 came back two weeks later. Session 2 was on May 27. That’s when Dr. Petch walked me through everything the panels found, including one marker that came back above the safe limit.
Frequently Asked Questions
What is the Individual Longevity Program at Healthi Life Bangkok?
The Individual Longevity Program at Healthi Life is a 3-month physician-led protocol designed by Dr. Sarassawadee Suwanjinda (Dr. Petch). It is structured around six medical pillars: diagnostics and biomarkers, nutrition and metabolic optimization, hormonal balance, gut microbiome and inflammation, sleep and recovery, and performance and biological age. The program is available in four tiers, ranging from ฿50,000 to ฿150,000, each activating progressively more pillars. It is not a wellness package; it is a clinical protocol built from your individual biomarker data.
How much does the Elite Tier longevity program cost at Healthi Life?
The Elite Tier costs ฿115,000 for a 3-month program. It covers Pillars 1 to 4, includes 12 IV drip therapies and 5 consultations with Dr. Petch. Pricing across all tiers ranges from ฿50,000 (Foundation) to ฿150,000 (Ultimate). Final investment is confirmed after a complimentary discovery consultation.
What tests are included in the first session of the longevity program?
Session 1 is entirely diagnostic. It includes an InBody 270S body composition scan, a full blood panel covering hematology, inflammation, and vascular markers, urine analysis, an epigenetic age test measuring 11 individual organ ages (PPSpan), a cancer screening panel, and a heavy metals panel. A gut microbiome stool test is completed at home after the appointment. The first session also includes an introductory IV drip therapy, in my case, a full-body detox protocol targeting inflammation and mitochondrial function.
What is epigenetic age testing, and what does it measure?
Epigenetic age testing measures how old your body is functioning at a biological level, independent of your chronological age. The PPSpan test used at Healthi Life goes further than a single biological age number. It breaks down the biological age of 11 individual organs, including the heart, brain, kidneys, and liver. It also measures your pace of aging: how many months you biologically age per calendar year. This allows the medical team to identify which organs are aging faster than expected and target interventions accordingly.
How is a longevity program different from a regular health check-up in Bangkok?
A standard health check-up is designed to detect existing diseases. A longevity program at Healthi Life is designed to identify optimization gaps and biological imbalances before they become disease. The program combines 80 to 120 biomarkers across six medical pillars, integrates wearable data with lab results, and produces a personalized 3-month intervention protocol covering IV therapy, nutrition, supplementation, and exercise guidance. It is physician-supervised throughout, with monthly check-ins and real-time monitoring between sessions.
Can international visitors do the Individual Longevity Program at Healthi Life Bangkok?
Yes. Healthi Life has treated guests from more than 50 nationalities and offers multilingual support in English, Thai, Chinese, Arabic, and French. International visitors can begin with a complimentary discovery consultation, either in person or remotely, to determine the right program tier. Medical concierge services are available for fly-in guests on the Ultimate tier.
What happened when the Session 1 lab results came back?
My Session 1 lab results were reviewed during Session 2 on May 27, 2026. One marker came back above the safe limit, with no prior symptoms and no warning signs. It was caught only because the full panel was run. Dr. Petch presented the findings and built a personalized 90-day intervention plan based on the complete diagnostic picture. Full results and the protocol are documented in Session 2.
