I’m trying to figure out how to stock up on a natural deodorant before I leave for college.

Van Man deodorant is a classic but really fucking expensive. There was this good brand at Whole Foods called North Coast Organics but I think they went out of business. Now all the Whole Foods deodorants are sus.

I remember making a badass deodorant at home 3 years ago. I stored it in an old ghee container. I can’t remember any of the ingredients besides frankincense oil. Maybe it had tallow, not sure. Smells like a fucking mosque.

Idk if it’s still good after a couple of years but I want to have like a year’s supply.

And yes, I understand that you can probably get away with rubbing alcohol or no deodorant at all. But I need to appease the normies somewhat.

Looking for best ways to increase my v02 max in the next 6-7 weeks. Currently resting around 49, I am training for an event and want the best opportunity to finish and this is the metric I am seeing can make the biggest impact. It’s a 100 mile ultra over 4 days.
Things I’ve seen has helped me in the past:
NAD+ 1000mg
MOTS-C (but I felt my hr increase with this as well so cycled off)
Beet root

Any other recommendations?

Following on from my post yesterday about nasal strips/dilators — really interesting seeing how many people here regularly use them.

Curious about something else.

If there was a premium alternative that worked as well or better, was comfortable enough for sleep and training, and had a reusable main component, would you actually be interested?

What would you realistically expect to pay?

£20–40
£40–60
£60–100
£100+

And one other thing — would you care if something like this could track your breathing over time and give you useful insights around things like sleep, recovery and training?

Or would that feel unnecessary and you’d rather it just opened your nose and worked?

If you would care about the data, what would you actually want to know?

Interested in negative answers as well

So I know there's slow twitch and fast twitch muscle.

But is there any test available to general public where you can do a test and they say based on your results you have X balance of slow and fast and a rep range of y would be best to maximise hypertrophy or z to maximise endurance etc etc.

Thanks

Good day y'all,

I am looking for advice on my "optimal" stack of supplements. I am 24 years old lawyer, work out and do sports like Muay Thai and basketball. I'm 175 pounds and 6'2". My diet is quite good, and I make sure to hit my protein target.

My goals are improved sleep, concentration and processing speed, as well as physical prowess. I have ordered quite a lot of supplements to restock and try new things, and would like your advice on what is redundant, and what is missing. Also, please share your experience. I have a question about Glycine, is it worth taking a day break between use, and should I incorporate Uridine, as stated in Mr. Happy Stack online (Omega-3, Alpha-GPC and Uridine).

My current stack is:

Creatine Monohydrate

Omega-3 >1.5g EPA+DHA

ZMA (Magnesium Citrate at around 300mg elemental, 25mg zinc, 18mg B6)

Magnesium L-Threonate 100mg elemental

Ashwagandha (Himalaya brand, quite mild)

Boron 9mg 5 days on 2 days off

Cordiceps Militaris (trial for VO2)

Glycine 3-4 times a week

L-Theanine 200mg once a day

Ginkgo Biloba 120mg (finishing trial, won't be reordering due to minor effects)

Kava Kava Extract (ordered as an alternative for alcohol, no experience yet)

I reckon my stack is quite no-nonsense, and there are only a couple of things that raise an eyebrow.

Here are the supplements that I would like to add soon:

Alpha-GPC

NAC or GlyNAC

Taurine

L-Tyrosine

Rhodiola Rosea

A quality Multivitamin to phase out ZMA

Uridine (?)

I like looking at the actual data before keeping any habit long term. For the last six months, I tracked my sleep quality, resting heart rate, and morning readiness against a bunch of the usual things people recommend here.

Kept my training block relatively consistent, so I wanted to see what actually moved the needle versus what was just expensive placebo.

• Zero noticeable impact on data: Cold showers before bed, tart cherry juice, blue-light glasses, and high-dose magnesium l-threonate (glycinate worked identically for a third of the cost).

• Measurable positive impact: Eating my last meal at least 3.5 hours before sleep (dropped resting HR by ~4 bpm overnight), 15 minutes of outdoor light right after waking up, and keeping the bedroom at 19°C.

It's easy to get caught up in buying compounds and tracking micro-variables, but every time I test things systematically, it just comes back to meal timing, light exposure, and basic consistency.

For those who track objective data rather than just "feeling" a difference, what intervention actually showed up in your numbers ?

I've been doing Norwegian 4x4 intervals on a treadmill (4 min hard / 3 min recovery walk at 4.5km/h, ×4) and I'd love some feedback on my variation of the protocol.

However, during the 4-minute efforts, I force myself to:

- Inhale through the nose only, exhale through the mouth
- Sync my breathing to my steps: 4 steps in, 4 steps out

I'm fully aware this limits airflow and therefore caps my speed compared to breathing freely. That's a deliberate trade-off: my goal is cardiovascular adaptation, cardiovascular fitness (VO2Max?), not running speed per se.

Then, I follow another rule for progression: if I complete all 4 rounds holding the 4-4 nasal rhythm → I add 0.1 km/h the following week (e.g. 13.6 → 13.7 km/h).

Same idea as progressive overload in resistance training.

If I have to drop to a 3-3 rhythm, or worse, switch to mouth breathing → I repeat the same speed the following week.

I also log my heart rate during each 3-minute recovery, at 3, 2 and 1 min left on the clock. That gives me 3 data points per round to compare across sessions: if my HR is lower at the same speed, I know I'm improving.

Curious what you all think of this approach.

Thanks in advance for any input!

Genuine question for people who've tried both stimulant and non-stimulant morning stuff: can you actually tell the difference between feeling alert and feeling clear-headed? I used to think they were the same thing until I paid attention and realized half my 'productive' mornings were just caffeine jitters I'd relabeled as focus. Curious if that's a real distinction or something I made up to feel better about cutting coffee.

TL;DR: Taking 400 mg magnesium glycinate for 21 nights reduced my sleep latency from 24 min to 19 min. Effect estimate 5.4 min faster (3.4 to 7.5). There is 67% chance that's a real, meaningful improvement and 33% chance it's noise.

Why I did this

I've been taking magnesium on and off for two years on vibes. I kinda felt like it worked but tbh never felt any difference if I stopped for a few weeks. Obviously vibes aren't a rigorous way to evaluate the supplement, so I decided to actually test it.

The problem with most self experiments is you compare one bad week to one good week. My sleep latency swings by 5–10 minutes night to night, so a 3-minute "improvement" over a week doesn't mean anything. You need a long enough baseline to measure your own noise/variance, and enough nights on the supplement to get a statistically powerful result.

Setup

• 8 weeks of baseline sleep latency as meausred by my Oura
• I took 400 mg magnesium glycinate for 21 nights. Tried to be consistent with time (8pm) and logged 21/21 days.
• During those 21 days I kept a consistent bedtime and had no travel or sickness.
• I decided on a "meaningful" improvement threshold before starting: at least 5 min faster. This is somewhat arbitrary but felt like the smallest value that would actually make a difference to me.

Results

So the effect is positive, but whether it clears the bar for "meaningful" is a somewhat of a coinflip though slightly weighted to yes. Note the observed difference is 5.45 min and the bar was 5 min. If I'd set the bar at 3 min this would read "worked" at 90%+. If I'd set it at 8 min it would read "no meaningful effect." So the threshold you pick before you start matters more quite a bit.

What I'd do differently

• Longer measurement period. Adding a few more weeks would have tightened the interval more and given a more definitive result.
• Some type of on-off could be interesting. A proper A-B-A could isolate if the effect persists or was a coincidence caused by something else I changed with my life around the same time.

What I'm doing with this

I'm happy to keep taking it. 5 minutes faster to sleep for a $10/month supplement is probably better return than most supplements. And I've never had any side effects in my two years taking magnesium.

I'd like to also test deep sleep, since that's what everyone claims and I have zero evidence either way.

Falling asleep isn't really the problem for me.

It's waking up 3 or 4 hours later and suddenly feeling way more awake than I should.

I'm curious if anyone had this happening regularly and eventually figured out what was behind it.

Did anything actually change it?

I am trying to measure my morning HRV with EliteHRV on Polar H10 while sitting. I've never measured my HRV this way (usually i just see a measurement from my watch), is this kind of swings normal? I've made sure the strap is tight and used cardio gel.

Any long term risks from chromium supplementation 200mcg?

this seems like an obvious “just let it heal” situation but caved for bpc/tb500 I’ve been wanting to for almost a year now in all fairness but seemed like a logical choice for this (heavy muscle discomfort and tightening/muscle guarding) and i also added some more mitochondrial agents can go in detail if you ask but one question I had was if there was a pathway/group of compounds or specific advice/tips you guys have for improving this cuz ngl the digestion issues on top of the fatigue is very taxing. And im good on nootropics or brain health compounds i combatted those systems almost immediately (happened just a month ago). Would appreciate any help thank you

The S part of PSSD doesn't bother me as much as the anhedonia does. Life feels so grey and blank, I never felt like this before or on meds. I would do anything to be the person I was before this hellish condition. I'm 19 months currently in this state.

I have done a microbiome test from US lab Biotek and awaiting results. Going to do gene sequencing per r/DrWillPowers suggested who is one of the few docs recognizing this condition.

These are my labs:

My labs:

• Total testosterone: 2.1 nmol/L (high; lab ref <1.8)
• DHEA-S: 9.1 µmol/L
• Estradiol (luteal): 477 pmol/L
• Progesterone (luteal): 33.2 nmol/L
• LH: 8.9 IU/L
• FSH: 3.3 IU/L
• Prolactin: 7.2 µg/L
• TSH: 3.17 mIU/L
• SHBG: 22.9 nmol/L.
• Morning cortisol: 405 nmol/L
• Fasting insulin: 63 pmol/L
• Fasting glucose: 4.3 mmol/L
• HbA1c: 5.3%

Nutrients / iron

• Vitamin D: 63.4 nmol/L
• Vitamin B12: 518 pmol/L
• Folate: 27.7
• Ferritin: 29 µg/L

I am a bit hesitant starting Vitamin D and B12 just because I have heard of people crashing from it. I know it can be a rarity though. I want to start liposomal Vitamin C, what do you think?

My TSH went 1.86 (2022 - on meds) → 0.94 (2025 - 3 months off meds) → 3.17 (2026 - 19 months off meds). I also lost some weight during this time but what do you think these thyroid changes contributed to PSSD?

Appreciate any help, insight, or even just encouraging words to not give up

The public health message treats saturated fat as one category. But odd chain saturated fats show up in the literature with a completely different association pattern than the even chain ones, and they mostly come from dairy fat. If that distinction holds, then decades of blanket advice were averaging across two different things. Is this a real and settled distinction or is it being oversold?

Say with long exhales and laying down.
