Creatine At 57: My 12‑Week Strength And Focus Experiment

Why I bothered with creatine at 57

I am 57, Dutch, and very aware that my deadlift will not magically go up on its own anymore. The default is loss. Muscle, strength, and probably brain power if I let it slide.

Creatine has been sitting in my "should probably test this properly" pile for years. It is one of the few supplements that has real data behind it. Strength, power, maybe some cognitive upside. Also cheap. Also boring.

This winter I finally ran a structured experiment. Twelve weeks. Daily creatine. Track strength. Track focus. No broscience filters, no "felt swole bro" notes. Just simple numbers and a daily log that I wrote before I knew the results.

The ground rules

I wanted something boring and repeatable. So I set it up like a small dev experiment. Minimal moving parts. Clear metrics.

Protocol

• No loading phase. 3 g creatine monohydrate per day, every day.
• Plain bulk powder from a generic Dutch vendor. Unflavoured.
• Taken with my first meal, not fasted. Mixed into yogurt or a shake.
• Duration: 12 weeks on creatine, 3 weeks baseline before.

Training

I coach baseball and lift like a dad who still pretends he is an athlete. So not a newbie, but not a powerlifter either.

• Strength days: 3x per week. 45–60 minutes. Focus on the big lifts.
• Conditioning: 1–2 light sessions. Mostly sled work, some intervals.
• No program change when creatine started. I kept my template identical.

Sleep and food were not perfect, but they were consistent. That matters more than macros you pretend to hit.

What I measured

• Weekly strength metrics on four lifts.
• Bodyweight, morning, after bathroom, no clothes.
• Subjective focus log: a daily 1–5 rating plus a short note.
• Sleep from Oura, but only as a sanity check, not a target.

I am not running a lab here. I am running my life. So I wanted just enough tracking to see patterns, not enough to turn it into a second job.

Baseline: 3 weeks of just lifting

For three weeks before starting creatine I ran the same program and logged everything.

Strength test once per week. I used a conservative 3RM instead of 1RM. I care more about repeatable triples than about a single Instagram PR.

Baseline strength metrics

• Trap bar deadlift 3RM: 150 kg
• Front squat 3RM: 80 kg
• Bench press 3RM: 85 kg
• Weighted chin up 3RM: bodyweight + 15 kg
• Bodyweight: 84.2 kg average

Across those three weeks, numbers floated a bit but did not trend. Normal noise. Some days better, some days worse. Nothing you would call progress.

Baseline focus log

I rated focus once per day on a 1–5 scale, where 3 was my "normal".

• Average focus: 3.1
• Standard deviation: 0.6
• Plenty of 2/5 afternoons after heavy coaching days

Notes from my log during those three weeks are not glamorous. Stuff like:

• "Brain fog after lunch, coding felt like pushing through syrup."
• "Good morning session, dead by 16:00. Switched to admin."
• "Needed a second coffee at 11:00 just to get moving on client work."

So that is my baseline. A decent lifting 56 year old who fades around 15:30 and needs a coffee strategy to keep development work moving.

Weeks 1–4: the boring phase

I started creatine on a Monday. No loading, no fireworks, just 3 g in my breakfast and a note in my tracker.

Strength changes

Here is how the numbers moved in the first month.

• Trap bar deadlift 3RM: 150 → 152.5 → 155 → 155 kg
• Front squat 3RM: 80 → 82.5 → 82.5 → 85 kg
• Bench press 3RM: 85 → 87.5 → 87.5 → 87.5 kg
• Weighted chin 3RM: +15 → +17.5 → +17.5 → +17.5 kg
• Bodyweight: 84.2 → 84.9 kg average

If you showed me only these numbers without context, I would say: decent linear progression for a consistent month of training. Nothing magical.

Which is the entire point. Creatine does not give you a new nervous system. It just nudges your ability to do a bit more work and recover a bit better, which looks extremely boring week to week.

Focus log, weeks 1–4

This part surprised me a bit, mostly because I had low expectations.

• Average focus: 3.4
• Standard deviation: 0.5
• Fewer "2" days, more "4" days, especially mid‑week

Typical log notes:

• "Leg day this morning, but coding from 13:00–16:00 felt surprisingly clean."
• "Mild headache, but focus fine. Could actually finish the React refactor without procrastination."
• "Still tired after coaching, but not completely wrecked mentally."

I would not call this proof of anything yet, but the trend was already that my lower bound of focus was moving up. Fewer zombie afternoons, even on training days.

Weeks 5–8: where it got interesting

By week 5 I expected things to level off. Creatine stores should be saturated around this point on a low dose. If there was a benefit, this is where it should show.

Strength metrics, weeks 5–8

• Trap bar deadlift 3RM: 155 → 157.5 → 160 → 160 kg
• Front squat 3RM: 85 → 87.5 → 87.5 → 90 kg
• Bench press 3RM: 87.5 → 90 → 90 → 92.5 kg
• Weighted chin 3RM: +17.5 → +20 → +20 → +20 kg
• Bodyweight: 85.3 → 85.8 kg average

That is roughly a 6–8 percent increase in working strength across the board over 8 weeks on top of my baseline. For someone already trained, at 56, that is not nothing.

Could I have done that with training alone? Maybe. But my training template was a copy‑paste from the previous block. Volume, intensity, and frequency were the same. Sleep quality did not improve. Stress did not vanish. Yet the progression curve steepened.

Subjectively, two things stood out:

• I almost never bailed on the last planned set.
• My joints complained less between sessions, especially knees and elbows.

That second one matters. At this age you do not lose strength because your muscles fail. You lose it because your connective tissue taps out first.

Focus log, weeks 5–8

• Average focus: 3.7
• Standard deviation: 0.4
• Still some "2" days, but now clearly linked to late travel or bad sleep

Log notes shifted tone. Less complaining, more annoyance at interruptions.

• "Deep work block from 9:00–12:00, almost no context switching. Creatine or placebo, not sure, but I will take it."
• "Morning lift, then 4 hours of frontend work. Felt physically tired, mentally fine."
• "Got pulled into unnecessary Slack noise, noticed I could get back into the code faster once it stopped."

That last point is hard to quantify, but I felt the cost of distraction went down a bit. Getting back into a component or a complex Tailwind layout felt less like re‑parsing a foreign codebase.

Weeks 9–12: did it flatten out?

I expected a plateau around here. There is only so far you can push numbers while keeping volume and lifestyle constant.

Strength metrics, weeks 9–12

• Trap bar deadlift 3RM: 160 → 162.5 → 165 → 165 kg
• Front squat 3RM: 90 → 92.5 → 92.5 → 95 kg
• Bench press 3RM: 92.5 → 92.5 → 95 → 95 kg
• Weighted chin 3RM: +20 → +22.5 → +22.5 → +22.5 kg
• Bodyweight: 86.0 → 86.2 kg average

So from the start of creatine to week 12, the total change looked like this:

• Trap bar deadlift 3RM: 150 → 165 kg (+10 percent)
• Front squat 3RM: 80 → 95 kg (+18.7 percent)
• Bench press 3RM: 85 → 95 kg (+11.8 percent)
• Weighted chin 3RM: +15 → +22.5 kg (+50 percent load, same reps)
• Bodyweight: 84.2 → 86.2 kg (+2.0 kg)

I did not get leaner. The mirror says maybe a little more fullness in shoulders and upper back, but nothing dramatic. Most of the extra 2 kg is probably water and some real tissue.

The main thing is this. I did not change the template. Volume stayed sane. I still had bad sleep weeks and real life in between. The numbers still climbed.

Focus log, weeks 9–12

• Average focus: 3.8
• Standard deviation: 0.4

That is not a massive jump from weeks 5–8, but the stability was better. Fewer swings. The floor felt higher.

Notes became shorter, which is actually a signal. When things are broken, I write more. When things just work, I log less.

• "Good focus, nothing special."
• "Solid coding block, no afternoon crash."
• "Slept 5.5 hours. Brain should be toast. Somehow managed three client calls and refactoring without wanting to crawl into a hole."

I am not claiming creatine fixes sleep deprivation. That would be nonsense. But on bad sleep days, the drop‑off felt smaller.

Side effects, annoyances, and things that did not happen

I had a list of things I expected might go wrong. Bloating. GI issues. Random headaches. Maybe sleep trouble.

Here is what actually happened.

• Bloating: None. My waist measurement stayed within 0.5 cm.
• GI issues: Two days of slightly loose stool in week 2. Then nothing.
• Cramping: Zero. I drink a normal amount of water, nothing extreme.
• Sleep: No change that I can link to creatine. My Oura data is the same mess it always is when baseball season starts.
• Hair loss: No visible change. My hairline is already vintage. Hard to make it worse.

The only actual annoyance was the powder itself. It does not dissolve perfectly in cold liquids, so you get a bit of sandy texture if you just dump it into water. Mixed into yogurt or a shake it is fine. Very low friction.

What I think creatine actually did

People love to treat supplements like frameworks. You see the same pattern. Overhype. Then backlash. Then everyone pretends they always had a nuanced take.

Here is my non‑nuanced take, based on these 12 weeks.

Strength

At 56, with years of lifting behind me, packing 10–18 percent onto my core lifts in 12 weeks without a volume jump is not normal for me. I have run similar templates without creatine and the slope was shallower.

So my honest reading is this. Creatine did not change the game. It did give me just enough extra gas in the tank to:

• Squeeze out one more clean rep in the last set.
• Recover better between heavy days.
• Increase load slightly faster than usual.

Those small edges add up over weeks. Especially when you are older, where every percent is expensive.

Cognition and focus

This one is messier, but I still have an opinion.

My focus ratings went from 3.1 to 3.8 on average over the experiment. Could that be noise? Could it be a placebo because I wanted creatine to help? Sure.

But two things felt real to me.

• The low days were less low. I still had tired days. I just did not get that sticky brain fog as often.
• Task switching cost dropped. I could jump from coaching logistics to frontend bugs to writing without feeling like my brain had to reboot completely.

Mechanistically, there is some evidence for creatine helping brain energy buffering, especially in older people or those with lower dietary intake. I am not trying to be a paper. I am just saying the day to day experience matched that story reasonably well.

Would I keep using it?

Yes. For me, creatine has moved from "interesting tool" to "default setting".

Here is my setup going forward:

• 3 g per day, no cycling.
• Take it with food, usually breakfast.
• No loading phase, ever. No need.
• Keep an eye on weight so the quiet creep does not turn into a real bulk.

If I ever see bloodwork shift in a weird way, or if my kidneys decide they had enough of my experiments, I will reassess. For now, there is nothing in my data or how I feel that suggests I should stop.

Who I think should actually care

I am not going to tell 22 year old lifters to hop on creatine. They already did, ten years ago.

I am more interested in people like me.

• Mid‑40s and up.
• Lifting at least twice per week.
• Doing real work with their brain most days.

If that is you, and you have your basics in order, creatine is a low drama lever. Cheap. Safe for most people. Small but meaningful edge on strength and probably some help on focus or mental stamina.

Just do not expect fireworks. Expect the training sessions to feel slightly more reliable. Expect the bad days to be a little less bad. Expect your numbers to move in a way that feels suspiciously steady.

How I would run this experiment again

If I reran this as a cleaner N=1 study, I would tweak a few things.

• Use double blind placebo blocks for four weeks each. Have someone else control the powder.
• Add a short cognitive test battery three times a week. Simple, repeated tasks, not just self ratings.
• Track total weekly training volume more precisely to see if creatine let me do more work without planning to.

But that level of rigor is for a paper. For my life, this setup was enough. Stronger lifts. Slightly higher focus. No drama.

If you are 50‑plus, lift, write code, and want a low risk experiment to run this year, creatine is a solid candidate. Just treat it like a boring dependency. It will not ship your project for you. It might help you push one more commit before you shut the laptop.
