Good day, y'all,

I have been having conversations with my Muay Thai coach about further improvements in training, and he is a proponent of steroid use, and tries extensively to convince me that it is a route to consider. I have always been against using steroids, but it does sounds appealing. I highly doubt I will be trying it, but interested to hear about your opinion. I'm in my mid twenties, work as a lawyer, and do fitness as well as Muay Thai.

In your opinion, are testosterone injections safe for one cycle in a year if blood work is done consistently, and are there any other steroids that are not as harmful. I hear a lot about harms such as infertility, but would like to learn more. It is my understanding that severe side effects occur when doses are increased or compounds are used that are not well researched. Is testosterone safe to use if LH is also taken with it, looking forward to all the input.

I've been looking at these "ultra" multivitamins lately, and I'm starting to feel like the ingredient lists are getting ridiculous. They brag about having 30 different fruits, veggies, and mushrooms, but when you look at the actual dosage on the back, it's like 10mg of a proprietary blend.

I know a lot of this stuff just ends up as expensive urine, but it got me wondering: which parts of a complex multi actually matter, and which parts are pure filler?

For example, if I see a multi with Magnesium Oxide instead of Magnesium Glycinate, I know it's probably cheap filler. But what about all those added "superfood" extracts? Are there any specific added ingredients (like certain forms of B vitamins, zinc, etc.) that you actually look for because you know they'll be absorbed? And which ones do you immediately recognize as a red flag that the company is just padding the label?

I'm trying to separate the genuinely useful compounds from the fairy dust. What are your personal "dealbreaker" or "must-have" ingredients when reading a multi label?

Due to the pressure of work, I often toss and turn for 2 hours and can't fall asleep, which leads to my poor state the next day. I can't concentrate on my work and have been sleepy.

To fix this, I bought a sleep supplement that promises faster sleep. Last night, I got into bed at 10:30 PM. I could feel my brain getting quiet, and according to my Apple Watch, I was asleep by 10:35 PM. I fell asleep in just 5 minutes! I was thrilled.

But why am I still tired and awake? After trying this product for half a month, I still feel sleepy in my office, which makes me feel that the money is wasted, because it doesn't give me a restorative rest, but just makes me faint!

Do you have similar experiences?

When two people use the same VNS device at the same intensity, it sounds as if they are receiving the same dose. They may not be.

The number shown on the device describes the electrical output, but not which nerve fibers were activated or what changed in the body.

The vagus nerve is not a single electrical cable. It contains multiple bundles of fibers connected to different organs and carrying different signals. Which fibers are activated depends on the person’s anatomy, electrode position, waveform, and device design.

This means two people using the same settings may not actually be receiving the same stimulation.

That is one of the most useful findings to emerge from the NIH SPARC program, which has invested more than $350 million in mapping peripheral nerves and developing more precise forms of neuromodulation.

Researchers found substantial differences between human, pig, and rat vagus nerves. Human vagus nerves also vary considerably from person to person, including nerve diameter, fascicle number, fascicle position, and the thickness of tissue surrounding the fibers.

Computer models suggest these differences can change which fibers an electrical pulse reaches. The same current and pulse width may stimulate one combination of fibers in one person and a different combination in someone else.

For someone using or comparing VNS devices, this has several practical implications:

• The intensity displayed by the device is not the same as the dose received by the nerve.
• A stronger sensation does not necessarily mean more effective vagus nerve recruitment.
• Tingling or muscle contraction shows that electricity reached tissue, but not which nerve fibers were activated.
• Copying another person’s settings may not reproduce their physiological response.
• “Level 5” on one device may not be comparable to “level 5” on another device.
• Increasing intensity may recruit additional fibers, including fibers associated with unwanted effects.

SPARC researchers are now combining human nerve maps, computational simulations, implanted VNS data, and physiological recordings to connect three things that are usually discussed separately:

What stimulation was delivered, which fibers were recruited, and what changed in the body.

That could move neuromodulation away from trial-and-error programming.

A future closed-loop system might monitor heart rate, breathing, digestion, neural activity, or another relevant signal. It could then adjust stimulation according to the measured response instead of repeatedly delivering one fixed program.

The biggest shift is conceptual. The true dose of neuromodulation may not be the number shown on the device. It may be the specific neural and physiological response produced in that individual.

The next major advance in VNS may not be a stronger stimulator. It may be a way to verify which fibers were actually stimulated and what changed in the body.

Has anyone paired Dr Irwin’s NO booster with a 5mg tadalafil?

For a while I was drinking around 1–3 Vita Coco coconut waters every day, sometimes even more. Other than that, I mostly drink regular water and occasionally chocolate milk, protein drinks, and orange juice.

I kept having these random episodes where I’d suddenly feel dizzy/lightheaded, really gassy and bloated, and just generally weird or “off.” It wasn’t constant, which made it hard to figure out what was causing it.

After my last episode, I realized how much coconut water I’d been drinking and decided to completely stop. It’s been about two days now, and today I’ve felt AMAZING.

No dizziness, no bloating, no weird episodes, nothing.
I’ve also started drinking kefir instead and my stomach has been feeling much better.

Obviously I can’t say for sure that the coconut water was the cause, but now I’m wondering if drinking that much every day was messing with my stomach or electrolytes somehow.
Has anyone else experienced dizziness, bloating, gas, or just feeling “off” from drinking a lot of coconut water? Especially Vita Coco?

have heard mixed opinions but if you have the money for primo, is nandrolone still worth to add to the stack at a low dose (150-200mg) or do the sides always outweigh the positives?

Hi all,

I have a good sleep schedule and consistently get 7-8 hours per night but still ALWAYS feel groggy and sleepy in the mornings.

This has been going on for years now and I am desperate for a solution.

Any help is appreciated, happy to confirm any details

Hello everyone,

I've struggled with an elevated heart rate this year and figured that if I am to recover from whatever is causing it I should quit the nicotine pouches I've been on daily (10-15 pouches of 12-15 mg each) for years now. I quit cold turkey and it's now been 27 days.

Quitting went surprisingly well and I haven't missed it for a minute. My reduced health situation could be a factor.

While my baseline heart rate is lower (nicotine tends to spike your HR), I've had an increase in anxiety, anxiety attacks and depression after quitting. It's been terrible. Quite a few visits to the ER. The last week I've also been getting really sweaty hands and feet. Only after remembering what some other people have written on other forums in the past I started wondering and did a search.

For me, it would help a ton if this is the case as I really don't understand why I should be having this anxiety right now.

I quit in 2024, too, and can't recall it being like this, but maybe my health situation is different and it's also 2 1/2 years more of daily high nicotine doses.

According to a study from Yale it can take around 6-12 weeks before the brain is back to normal.

I'm just bringing this up for discussion and knowledge sharing. If I were to do it again, I would have tapered more and used a nicotine substitute for a while (patch perhaps).

Also curious if anyone has any idea if there's anything one can do to alleviate the withdrawal symptoms? I've even considered starting with a patch now just to see, but I'm not sure.

Emergency Psychiatric Effects of Nicotine Vaping Cessation: A Narrative Review - PMC

"Across study types, nicotine withdrawal is consistently associated with anxiety, irritability or agitation, depressed mood or anhedonia, sleep disturbance, and difficulty concentrating. In acute care environments, nicotine withdrawal has also been associated with agitation or delirium phenotypes in hospitalized and ICU populations. Furthermore, e-cigarette use has been linked to increased odds of suicidality and psychotic-like symptoms in some observational studies. Finally, case literature documents severe psychotic presentations that are temporally associated with e-cigarette use or nicotine withdrawal, although causality is difficult to establish."

Study shows unrelenting grip of nicotine withdrawal – UW–Madison News

"In one of those clusters, the withdrawal symptoms followed a predictable path of starting strong, then gradually declining. A second cluster reported a gradual increase in withdrawal severity over 60 days. A third cluster experienced a small improvement over two weeks, but then their symptoms leveled off and persisted.

Baker said the two “atypical” clusters experienced higher relapse rates than the first group. “Smokers who showed increasing or prolonged withdrawal had double or triple the risk of relapse as other patients,” he said.

The study also found that the “atypical” patterns are actually quite common. In the first study, 39 percent of subjects fell into the second or third clusters; in the second study, the number was 68 percent."

I sleep good and I supplement magnesium glycinate and l theanine but it’s not enough, I need advice.

I realized my cortisol and stress was pretty high a little while back and I’ve reduced a lot of it my supplementing l theanine, magnesium glycinate and optimizing my sleep. But I want to lower it more.

All summer I went outside every morning for sunlight and honestly felt great. I slept better and needed less coffee.

Now it's dark until 7:30 and grey every day. Is 10 minutes outside under clouds still doing anything, or should I just get one of those SAD lamps?

What do you guys do in winter?

——————————
By the way, full disclosure: I’m the developer of Soltide. I’m interested in how people adapt their light routines as winter approaches, since consistency gets much harder when mornings are dark. I’m building Soltide around this space, so this discussion is genuinely useful to me. If anyone’s curious, here’s the app: https://soltide.bypop.dev

Feels like insulin has been blamed for many chronic conditions over the past couple of years. Would love this communities thoughts on this topic.

ACh Weird phenomena help?

Hey guys, I need advice on supplements to help with verbal fluency, word recall, and social confidence.

Context: I work in a highly social, demanding environment. I know what it feels like to be quick-witted and articulate, but right now I struggle with hesitation and overthinking when I speak.

I want to avoid hardcore stims (Adderall, high-stim pre-workouts) because they give me horrible stomach acid, a harsh head high, and jitters. I’m looking for something sustainable that calms social anxiety while keeping me sharp enough to think on my feet.

(Side note: I saw a rumor that Paracetamol increases verbal fluency by reducing social pain. Is this real or just placebo?)

My questions:

1. What stack actually helps with word recall and speaking clearly?

2. How do you stop the physical anxiety (racing heart/tight throat) when speaking up?

3. Any specific nootropics that help you find the right words without feeling "tweaked"?

Any advice or personal experiences would be amazing. Thanks!

I take 5mg Tadalafil occasionally, but the side effects on my head and cognitive function are really rough for one to two days. I experience heavy brain fog, sluggish thinking, and poor verbal recall as if my working memory is blocked. Along with that comes a mild headache combined with an annoying dull pressure behind my forehead and temples. Trying to clear this mental fatigue with caffeine did not help and only made me feel worse. Has anyone else dealt with this exact combo of brain fog and head pressure from low-dose Cialis, and did it ever go away for you?

29 natural male. Thoughts on my results. Anything stand out?

I love coffee

I was able to do 25 pushups, im 6'5 230lbs (260lbs before glp), I got my wife pregnant in may 2025, and havent worked out ever since (i know i know), NOW i cant do a single pushup without pain in my shoulders....am i mistakenly blaming GLP (tirz and reta, started in march 2026) for my shoulder pain and loss of strenght? is anyone familiar with this secondary effect?

So I’ve done a LOT of research about high quality sleep so here it is, in the simplest way I can put it.

I’m not going to blabber about circadian rhythm or anything bug like that even though I could go on forever, here is a simple but very effective nightly routine + a lil more.

For the example the bedtime will be 12pm and wake 8:30am, for an optimal 8.5 hours of sleep👌

10:30pm - take supplements
5-10mg melatonin
400mg elemental magnesium glycinate
400mg l theanine
(Mouth tape so you nasal breath)

Optional - glycine, Apigenin, and nasal spray on nights you can’t breath through your nose

11-11:30pm read whatever book you please, but it has to be in the dark with a red light.

11:30-12pm is when you close your eyes and try to fall asleep, from my experience I usually fall asleep pretty quickly.

Environment ‼️very very important‼️
You can do everything else right but if your room is too hot it isn’t worth it.
- I use a window unit to get my room between 60-67 degrees and you have to have a warm blanket because it being too cold can wake you up as well.
- also obviously you have to make sure it’s dark in your room and that’s pretty much it.

Note:
About the melatonin, melatonin is soooo fear mongered it’s not even funny, but if you do your research all the claims about say it messing up your natural production lowering your testosterone or whatever, there is no studies to back it up. , in some cases it’s the opposite.

In conclusion since I only said the basics all of this information is very important and it shouldn’t be skipped, and it even isn’t really a lot. And even tho if h there’s more to be said and more you could do if you just follow all I’ve said you’ll have really good sleep still.

And of course this is not medical advice.
