Carlos is 45 years old chronologically. Six months ago, his epigenetic biological age test (TruDiagnostic) showed 48 years. Today it reads 41. Seven years younger in half a year. It's not magic or a 3am Instagram ad. It's the measured, documented and replicable result of a protocol that any professional with a normal life can follow.
Carlos lives in Madrid, works in consulting (60 hours per week at peak times), has two young children and zero time for extreme biohacking. No daily infrared saunas or 72-hour fasts. Just interventions with maximum return per minute invested, based on studies and adapted to his reality. This article documents exactly what he did, why it worked and how you can replicate it without turning your life into a laboratory experiment.
What you'll learn here:
- The exact protocol Carlos followed week by week
- What test measured the change (and why that test is reliable)
- The 4 pillars that explain 80% of the result
- Mistakes that almost made him quit in month 2
- How to adapt the protocol to your real calendar
What is biological age (and why it matters more than your ID)
Chronological age counts birthdays. Biological age measures how much your cells have actually aged. You can be 45 on your ID and 52 at the cellular level (or 38 if you do it right). Current epigenetic tests, like the DNAm PhenoAge that Carlos used, analyse DNA methylation patterns — chemical markers that change with cellular wear and tear.
Studies in over 13,000 people published in Aging (2020) show that each year of accelerated biological age increases mortality risk from all causes by 7%. It's not a vanity metric. It's your cardiovascular system, mitochondrial function, immune response and cancer risk summed up in a number.
Carlos didn't do it for a number. He did it because at 45 he already noticed: slow recovery after effort, mental fog mid-afternoon, fragmented sleep, and that feeling his body was responding in slow motion. The test just confirmed what he already felt.
The starting point: Carlos's test and real situation
Initial test (February):
- Chronological age: 45 years
- Biological age DNAm PhenoAge: 48 years
- Rate of ageing (DunedinPACE): 1.18 (18% faster than average)
Life situation:
- Big4 consultant, average 55-60h/week
- Two children (7 and 10 years old)
- Sleep: 5.5-6.5h/night fragmented, frequent 3am waking
- Exercise: zero structure, occasional running
- Diet: "whatever I can" between meetings, work dinners 2-3 times/week
- Subjective stress: 8/10
Notable biochemical markers:
- HbA1c: 5.9% (prediabetes)
- C-reactive protein: 3.2 mg/L (moderate inflammation)
- Elevated nocturnal cortisol
- Vitamin D deficiency (18 ng/mL)
That was Carlos in February. Not an extreme case, but the standard Spanish professional with demanding life and body in survival mode.
The exact protocol (no magic, just applied science)
Carlos didn't do 30 things. He did 6, but he did them every day for 6 months. The key wasn't sophistication but adherence. Here's the complete protocol:
Pillar 1: Sleep as foundation (months 1-6)
Goal: move from 6 hours fragmented to 7.5 hours consolidated.
Concrete actions:
- Fixed lights-out time: 23:15 (negotiated with his partner)
- Nocturnal protocol: magnesium glycinate 400mg + glycine 3g + L-theanine 200mg at 22:30
- Bedroom: total blackout, 18-19°C, clean air (HEPA purifier)
- Zero screens after 22:00 (amber-lit Kindle ok)
- Progressive alarm with light simulating sunrise
Meta-analysis in Sleep Medicine Reviews (2019) with 400,000+ participants shows that each additional hour of deep sleep is associated with 0.5-0.8 fewer years of biological age. Sleep is when your body repairs DNA, clears senescent cells and resets circadian rhythms.
Carlos went from 5.5h average to 7.3h by month 2. The biggest change in any metric.

Pillar 2: 16/8 eating window (not extreme fasting)
Goal: give 16 hours daily metabolic rest without overcomplicating.
Actions:
- First meal: 13:00
- Last meal: 21:00
- Black coffee in morning ok, zero liquid calories outside window
- Two meals + snack if he trained
He didn't count calories. He didn't weigh food. Just respected the window and prioritised protein (1.6g/kg) + vegetables at each meal. Studies in Cell Metabolism (2019) show that 16 hours of fasting activate autophagy — the process where your cells recycle damaged components — without needing multiday fasts.
His HbA1c dropped from 5.9% to 5.3% in 3 months with just this.
Pillar 3: Strength training 3x/week (45 min)
Goal: build muscle mass = metabolic reserve.
Protocol:
- Monday/Wednesday/Friday, 6:45-7:30am (before the children wake up)
- Full-body: 5 compound exercises (squat, press, row, Romanian deadlift, military press)
- 3 sets of 8-12 reps, technical failure on last set
- Progression: +2.5kg every 2 weeks on main lift
Zero cardio the first 3 months. Strength only. Review in JAMA Internal Medicine (2022) with 30+ studies shows strength training 2-3x/week reduces biological age markers more than cardio alone. Muscle mass is an endocrine organ that secretes anti-inflammatory myokines.
Carlos gained 3.2kg lean mass in 6 months (DEXA scan). At 45 years old.
Pillar 4: Longevity stack (evidence-based ingredients)
Goal: fill nutritional gaps that diet doesn't cover.
Daily stack:
- Morning: NMN 500mg + resveratrol 250mg + omega-3 (2g EPA/DHA) + vitamin D3 5000 IU
- Night: magnesium glycinate 400mg + glycine 3g + zinc 15mg
- Occasional: berberine 500mg if meal high in carbs (work dinners)
It wasn't a stack of 30 bottles. It was 8 ingredients with clinical doses and specific timing. NMN and resveratrol in the morning to leverage sirtuins peak. Magnesium and glycine at night to deepen sleep.
Study in Nature Communications (2021) shows that NMN 300-500mg/day increases NAD+ by 40-60% in humans, improving mitochondrial function and insulin sensitivity.
Pillar 5: Stress management (the hardest part)
Goal: lower nocturnal cortisol.
Actions:
- 4-7-8 breathing (3 cycles) whenever he felt chest tightness in meetings
- 15-minute post-lunch walk, zero phone
- Infrared sauna 2x/week, 25 min at 60°C (gym near office)
- Weekly conversation with his partner about mental load (not Netflix autopilot)
The cortisol bit is real. Carlos measured it: dropped from 18.5 μg/dL (nocturnal) to 9.2 μg/dL in 4 months. Chronic elevated cortisol accelerates telomere shortening — the ends of your chromosomes that correlate with biological age — according to paper in Molecular Psychiatry (2020).
The sauna was his anchor. Twice a week, religiously.
Pillar 6: Natural light and circadian rhythm
Goal: reset biological clock.
Actions:
- 10 minutes natural light in eyes (no glasses) before 8:30am
- Blue-blocking glasses after 20:00 if using screens
- Zero white LED light in house post-dinner (amber bulbs)
It sounds trivial. It's not. Meta-analysis in Journal of Pineal Research (2020) shows morning light exposure advances melatonin phase and improves sleep architecture in 65% of cases. Dysregulated circadian rhythm is a silent accelerator of biological age.
The 3 mistakes that almost made him quit
Mistake 1: Wanting results in 3 weeks
What happened: by week 3, Carlos felt the same. Same tiredness, same weight, zero visible changes. Almost quit.
Solution: we agreed to measure only every 6 weeks (blood work + DEXA). Epigenetic changes take 8-12 weeks to manifest. The trap is expecting Instagram results in real biology.
Mistake 2: Skipping sleep for deadlines
What happened: month 2, critical project. Back to 5 hours sleep three nights straight. His recovery crashed. It took 10 days to return to baseline.
Solution: he marked sleep as "non-negotiable meeting" in calendar. If there was a deadline, he delegated or reorganised the next day, but sleep didn't budge. In 6 months he only had 4 nights <7h.
Mistake 3: Overcomplicating the stack
What happened: week 5, he read about peptides, metformin, rapamycin. Wanted to add everything.
Solution: brutal Pareto principle. 80% of the result comes from 6 things done well, not 30 mediocre. We kept the stack simple until month 4. Only then added berberine occasionally.
The results (biological age test after 6 months)
Re-evaluation test (August):
- Chronological age: 45 years (obviously)
- Biological age DNAm PhenoAge: 41 years (vs 48 initial)
- Rate of ageing (DunedinPACE): 0.89 (11% slower than average, vs 1.18 initial)
- Telomere length: 62nd percentile (vs 38th percentile initial)
Biochemical markers:
- HbA1c: 5.3% (no longer prediabetic)
- C-reactive protein: 0.9 mg/L (low inflammation)
- Nocturnal cortisol: 9.2 μg/dL (optimal range)
- Vitamin D: 52 ng/mL
- Lean mass: +3.2kg (DEXA)
- Visceral fat: -18%
What Carlos notices (subjective but real):
- Wakes at 7am without alarm, refreshed
- Constant mental clarity until 19h (previously crashed at 15h)
- Post-exercise recovery: 24h vs 48-72h before
- Zero afternoon sweet cravings
- Firmer skin (his partner notices, he doesn't)
What DIDN'T change:
- Still works 55h/week
- Still has work dinners
- Still has two young children
- Doesn't live in a biohacking retreat in Bali
How to replicate the protocol (adapted to your life)
You don't need to copy everything 100%. You need to identify your 2-3 levers of maximum impact and execute religiously.
If you can only do 3 things (absolute priority):
- Sleep 7-8h consolidated → everything else depends on this
- Strength training 3x/week 45 min → muscle mass is longevity
- 16/8 eating window → metabolic rest without overcomplicating
If you can add 2 more:
4. Basic stack: NMN + omega-3 + vitamin D + magnesium
5. Morning natural light 10 min + reduce nocturnal blue light
If you want the complete protocol:
Add stress management (sauna, breathing, walks) and measure every 6 weeks.
Mistakes to avoid:
- Starting all 6 pillars same day (recipe for burnout)
- Measuring every week (generates anxiety)
- Comparing yourself to full-time biohackers on Twitter
- Skipping sleep for anything else
Realistic timeline:
- Weeks 1-4: implement sleep + 16/8 fasting + strength (nothing else)
- Weeks 5-8: add longevity stack
- Weeks 9-12: incorporate stress management
- Week 12: first control blood work
- Week 24: biological age epigenetic test
Don't try to do it perfectly. Try to do it sustainably. Carlos had weeks at 60% adherence. It still worked because his 6-month average was 85%.

How to choose the right longevity stack
Carlos tried 4 different brands in the first 2 months. Most had subtherapeutic doses (NMN 125mg, omega-3 with 300mg EPA when you need 2000mg, magnesium oxide you don't absorb) or 30 ingredients mixed without timing logic.
The problem with the Spanish market is it's full of products designed to look complete on the label, not to function in your biology. More ingredients ≠ better result. Actually, it's usually the opposite: low doses of everything = wasted money.
When we designed the protocol, we looked for three things:
- Clinical doses (the ones used in studies, not half)
- Specific timing (morning vs night by mechanism)
- Evidence-based ingredients in humans, not just in vitro
At Longevitalis we developed exactly that: three complementary products covering cellular renewal (Vitalis Renew), nocturnal repair (LongeviNocturno) and dermal structure (LongeviSkin). No filler, no trendy ingredient marketing. Just what works, with the doses that matter, manufactured in Spain under GMP standards.
What to look for if you choose another brand:
- NMN: minimum 250-500mg/day (not 125mg)
- Omega-3: EPA+DHA total ≥2000mg (not generic fish oil)
- Magnesium: glycinate or bisglycinate form (not oxide or carbonate)
- Resveratrol: ≥150mg trans-resveratrol (not diluted grape extract)
- GMP certification and third-party testing

- Why only 3 products and not 30
- Vitalis Renew: why only 6 ingredients
- LongeviNocturno: the story behind the formula
- LongeviSkin: why collagen + vitamin C + hyaluronic acid
Possible side effects and precautions
Carlos had no serious adverse effects, but did experience normal adaptations in the first weeks:
Weeks 1-2 (16/8 fasting adaptation):
- Intense morning hunger (disappeared week 3)
- Slight pre-meal irritability (resolved with black coffee)
Weeks 1-3 (starting strength training):
- Severe DOMS (delayed-onset muscle soreness) after first sessions
- Need for 8h sleep vs 7h usual (resolved)
Week 1 (starting stack):
- Looser stools from magnesium (adjusted to 400mg from initial 600mg)
- Mild facial flushing from NMN niacin (normal, disappeared in 5 days)
Important contraindications:
- If taking anticoagulants: consult doctor before high-dose omega-3
- If you have medicated diabetes: 16/8 fasting may require dose adjustment (medical supervision)
- If you have diagnosed sleep disorder: nocturnal protocol needs adaptation
- NMN and resveratrol: theoretical interaction with chemotherapy (avoid without consulting oncologist)
Carlos had full blood work at week 0, 12 and 24 to verify everything moved in the right direction. Don't improvise with your health. Measure, adjust, measure again.
Frequently asked questions about Carlos's case
Does it work the same in women?
Yes, with nuances. The base protocol (sleep, strength, fasting, stack) works the same. Women may need to adjust:
- Shorter eating window in luteal phase (14/10 vs 16/8)
- Strength 2-3x/week vs 3-4x in men for same relative gains
- Slightly lower doses of some ingredients (magnesium 300mg vs 400mg)
Studies in Aging Cell (2021) show similar biological age reversal in both sexes with caloric restriction and exercise protocols.
How much does it cost to replicate the protocol monthly?
Economic breakdown (Spain prices):
- Longevity stack (NMN + resveratrol + omega-3 + magnesium + vitamin D): €90-140/month depending on brand
- Gym or home equipment: €30-50/month
- Biological age test (optional, only for measurement): €300 every 6 months
- Sauna (optional): €40-80/month depending on gym
Realistic total: €120-220/month without test, €170-270/month with biannual test. Less than a mid-range car. More impact than any health insurance.
Can you do it without biological age testing?
Yes. The test is useful for motivation and fine-tuning, but not mandatory. You can use cheaper proxy markers:
- Standard blood work every 3 months (HbA1c, CRP, lipid panel): €60-80
- DEXA scan every 6 months (body composition): €50-70
- Subjective tracking (sleep, energy, recovery)
Carlos measured biological age because he wanted hard data. But he felt the change long before the test.
Does it work in people over 50 or under 40?
Over 50: works the same or better. Studies in Nature Aging (2022) show lifestyle interventions have greater relative impact at 50-70 years than at 30-40, because there's more room for improvement.
Under 40: works for prevention. If your biological age is already lower than chronological, the goal is maintaining that advantage without reversal (because you're already good). The protocol adapts from reversal to maintenance.
What happens if you stop the protocol after 6 months?
Carlos continues with 80% of the protocol a year later. Results maintain if you maintain core pillars (sleep + strength + basic fasting). You can relax stack or sauna frequency without losing ground.
If you go back to 5h sleep, stop training and eat like before, your biological age will accelerate again in 3-6 months. Biology is dynamic. There's no permanent result without minimum maintenance.
Does the protocol interfere with regular medication?
Depends what medication. Cases requiring medical supervision first:
- Anticoagulants (warfarin): high-dose omega-3 can potentiate effect
- Antidiabetics: 16/8 fasting can cause hypoglycaemia if you don't adjust dose
- Immunosuppressants: some stack components may modulate immunity
- Antihypertensives: weight loss + exercise may require dose adjustment
Carlos took no medication. If you do, consult your doctor before starting. Especially the fasting and stack.
How much daily time does the protocol require?
Daily time breakdown:
- Sleep: 7.5h (non-negotiable anyway, you'd sleep poorly or well)
- Training: 45 min x 3 days/week = 21 min/day average
- Meal prep: +15 min/day by prioritising protein
- Morning light: 10 min
- Post-lunch walk: 15 min
- Nocturnal protocol (magnesium + routine): 10 min
Total active: ~70 min/day that you'd already spend eating, sleeping and moving. Just do it more strategically.
Conclusion: it's not an exceptional case, it's applied science
Carlos doesn't have privileged genetics. He didn't leave his job. He didn't hire a chef or personal trainer. He did nothing you can't do. He did 6 things with discipline for 6 months and measured the result with an objective test.
Biological age reversal isn't science fiction or aspirational marketing. It's metabolic engineering based on decades of research into sirtuins, autophagy, chronic inflammation and DNA repair. The mechanisms are there. You just need to activate them consistently.
The question isn't whether it works. The question is: Are you willing to prioritise the 3-4 things that really matter for 6 months? No tricks, no shortcuts, no miracles. Just optimised biology day by day.
If Carlos did it with 60 hours of work and two young children, you can too. Start with sleep. Add training. Incorporate fasting. The stack is the last step, not the first. And measure every 12 weeks to see if you're on the right track.
In six months, you might write your own success story.
