I'm not a doctor or a dietitian. I'm a 35-year-old desk worker who took zero supplements his whole life, then started boxing and got humbled. Now I'm trying things one at a time, on myself, and writing down what actually happens. This is my log, not advice.

Day 10 — humidity, sweat, and a 5K test
Sweated buckets today. Was it the weather, or is creatine pulling more water than I realized? 5K test tonight will tell me something.
What I ate today.
Nothing unusual — normal Korean meals across the day. No new foods, no experiments. I wanted today's variables to be as quiet as possible because of the 5K test later.
What I took.
Same stack — **creatine 5 g** and one **multivitamin** with a meal. Day 10. No changes.
The weather hit different today.
It was **brutally humid and hot**. Even sitting still I was sweating more than usual. And when I moved — walking, climbing stairs, just normal stuff — the sweat was excessive. Way more than what the temperature alone should explain, at least based on how I usually react to summer days.
So now I have a question I can't fully answer yet:
- Is it just the humidity, and my body is doing what it's supposed to?
- Is creatine making me hold more water, and that extra water is coming out as sweat under load?
- Or has the creatine quietly raised my training intensity — heavier sets, faster work — so I'm just doing more, and sweating more as a result?
I genuinely can't tell. All three are plausible. This is the kind of thing that needs more days of observation before I'd call it. I'll keep an eye on sweat rate vs. weather over the next week.
The 5K test — tonight.
My best 5K so far is a **4:80 / km pace** (yeah, that's slow — I'm a boxer first, runner a distant second). Tonight's goal is **4:30 / km**. A 30-second-per-km jump is aggressive, and I'm not pretending otherwise.
What's working against me:
- I've been doing almost no running lately. Boxing has been the priority, and conditioning on the bag is not the same as steady-state road pace.
- The humidity is going to make pacing miserable.
What might be working for me:
- Creatine. If the pump and the strength bumps in the gym are real, maybe there's a small carryover to short-burst running too. Or maybe creatine is dead weight for a 5K. We'll see.
- Boxing has at least kept my lungs honest.
Honestly I'd be happy with anything under 4:45. 4:30 is the stretch goal. I'll log the actual time in tomorrow's entry.
Overall condition.
**Okay, but drained by the weather.** The sweat is the standout, and I don't yet know how much of it to blame on the supplements versus the room temperature.
Run first, theorize after.
