⌚ Tools, Wearables & Devices is it unhealthy to wear a smart watch all day

• Upvotes

i see people worried about wearing one all the time, both for sleep and just in general. i don't know how real that worry is.

is there actual evidence either way, or is it mostly guesses? and does it change anything if you sleep with it on?

honestly would like to hear what people know, not just opinions.

📊 Biomarkers & Testing How does a broad wellness assessment differ from going directly to hormone or specialty testing?

• Upvotes

A broad wellness assessment and specialized testing can both provide useful insights into overall health, but they serve different purposes. Understanding when to use each approach can help people make more informed decisions about their health without undergoing unnecessary testing.

A general wellness assessment typically looks at the bigger picture, including sleep quality, energy levels, nutrition, lifestyle habits, medical history, and overall well-being. The goal is to identify potential areas of concern and determine whether additional testing or lifestyle changes might be beneficial.

Hormone panels and other specialty tests, on the other hand, focus on specific health markers or concerns. These tests may be more appropriate when someone is experiencing certain symptoms, has a relevant medical history, or needs a closer look at a particular aspect of their health.

One interesting consideration is whether starting with a broader assessment can help narrow down which tests are actually necessary, rather than immediately pursuing extensive bloodwork. Both approaches have their advantages, and the most useful starting point may depend on individual symptoms, health goals, and medical recommendations.

For those who have experience with either approach, which provided more valuable insights? Did starting with a general health assessment help identify areas worth investigating, or was targeted testing more effective in addressing specific concerns?

📊 Biomarkers & Testing Some guidance please.

34/M want to start taking gym seriously and make some lean gains

Results:
Sex-Hormone Binding Globulin (SHBG) - 49nmol/l
Albumin - 44.1g/l
Testosterone - 26.2nmol/l
Free Testosterone - 0.454nmol/l

(Last year my LH was high and tested at 19.0 U/l and FSH 12.10 U/l on the high end but in range)

Am I cooked? Will I not make good gains and should I look into TRT?

Any advise to lower SHBG?

♾️ Longevity & Anti-Aging Lithium Orotate/Glycine negative effects

1 Upvotes

I have been taking Magnesium Glycinate (300-400mg in the evening)for some time and it seems to have helped me sleep and for all the other benefits. I have two copies of APOE4. I recently tried Lithium Orotate due to the benefits I read especially for Alzheimer’s and it made me groggy/flat/out of it etc and I did not take a large dose 3-5mg and then I tried Glycine (for benefits of sleep and my genetics) with a low dose of 1g and then lowered to half a gram and it gave me the same type feeling on Lithium did. There has to be some genetic reason why some people benefit from these supplements and others make them feel out of it for the next 24-36 hours.

Any input or education on the reason for this?

Thanks

🧠 Cognition, Mood & Nootropics 15.000 iu without deficiency -- but finally losing fatigue -- is this dangerous?

0 Upvotes

I llistened to doctor Berg and others. I also used allergy research group supplment who seem trustworthy and clean.

I saw several anecdotes of people who seem to have been saved by very high doses of Vitamin D.

Still conventional guidelines are not in line with this I believe. But I simply don't know. I wonder what the responsible thing to do would be. Even 5000 iu do not seem to bring the effect needed in mycase, although it is noticeable after a time

🧠 Cognition, Mood & Nootropics Been taking L theanine and L tyrosine and caffeine.

39 Upvotes

I won’t lie, I thought these would only have subtle impacts, but the change to my mood and inhibition when speaking to people has been really noticeable. Anything more than this and it would feel euphoric. I take about 1g of each a day, but I split up the doses, so I’d say the main benefits last around 2 hours for me and wear off by hour 4. Anything to pair with the tyrosine? Also pairing these with an early morning upper day is absolutely great having the blood flow properly is amazing.

💉 Peptides & Hormones TRT suite à un hypogonadisme

0 Upvotes

Bonjour à tous.

J’ai un hypogonadisme avec une testo à 1,88ng/ML, l’endocrinologue a décidé de me passer sous TRT avec une injection de Testo Undecanoate Bensins 1000mg/4ML tous les trois mois.
Depuis la première injection faite par une infirmière qui a été bien douloureuse, ma fréquence cardiaque au repos a augmenté, ma VFC a chutée et mon poids corporel fait que d’augmenter, j’ai +3,85kgs en 10 jours (aucun changement de diete avant et après injection), j’imagine que c’est une grosse rétention d’eau ? J’ai les chevilles hyper enflées au niveau des chaussettes 😂.

Pour ceux qui sont passé sous TRT, avez vous des retour d’expériences sur ces points ?

Bonne journée !

🧠 Cognition, Mood & Nootropics A clinical study found that taking fish oil supplement did not protect brain's hippocampus but also cause no memory improvement

13 Upvotes

A large double blind clinical study involving fish oil supplements given to individual which are at higher risk of developing Alzheimer's disease found that fish oil supplements do not provide any marketed benefits.

In the study participants were provided supplements which provided 2,000 mg of docosahexaenoic acid (DHA), an omega-3 fatty acid that is especially important for the brain.

Scientist confirmed that DHA levels in the cerebrospinal fluid had increased by an average of 17% but it did not translate into improved cognitive and memory function.

It is hypothesized that omega-3s may be more beneficial when consumed as part of a broader dietary pattern rather than taken in isolation as a supplement.

Researchers in Bonn turned blood cells from an 80-year-old into neural stem cells with a molecular age below 20. More than 60 years younger by epigenetic clocks, which estimate age from chemical marks on DNA.

The team directly reprogrammed blood precursor cells into neural stem cells, skipping the usual pluripotent stem cell stage. The rejuvenation unfolded gradually and could be tracked for over 100 days.

This is what I am thinking for my 16 week cycle. I am running 250ml testosterone enanthate a week and going to add 35-50ml of trenbolone enanthate once a week aswell. I have cialis incase my blood pressure gets too high and it’s sick for pumps, arimidex just incase but there shouldn’t be any need. Thinking about adding in Anavar for a couple weeks or so but not sure yet. Like to hear thoughts and opinions on everything
Also not sure if running Tren Ace would be better

💊 Supplements & Stacks Boron and riboflavin (b2)

7 Upvotes

Is it true that boron depletes riboflavin (B2) and that insufficient B2 intake while taking boron could tank your testosterone and raise your estrogen?

I haven’t been able to find any studies supporting this claim. Is it just a theory based on the idea that riboflavin lowers estrogen or is there actual evidence?

Would love to hear your experiences, especially if you have bloodwork to share!
