Microbursts lift the skin into goosebumps. Her hair stands perpendicular, increasing the drag of my fingertips. She ask...

Doing magic mushrooms this Sunday. Protocol + dose: 5 grams + frequency: 1x/mo for 3 mo + objective: exploring longevity effects Measurement + 249 independent biomarkers + 29 vials of blood + brain scans + urine, stool, saliva, fertility + multi-omics profiling (DNA, epigenetics, metaboli...

If you're doing HBOT, this my protocol: 2 atmospheres 60 sessions in 90 days 90 min per 20 min of 100% oxygen via mask, 5 min break, repeat My chamber maintains ambient air (21% oxygen) reducing the risk of oxidative stress to the eyes (cataracts)....

I paused Metformin. A longevity staple in my protocol for 5+ years. But its effects on my body were shocking. It built up my energy capacity, but limited my ability to use 90% of it. Here’s what we found. 🧵...

A new longevity stem cell therapy in monkeys showed an estimated 3–5 yrs of biological age reversal, across 54% of tissues. Scaled cautiously to humans, could correspond to ~9–15 years of rejuvenation. If this replicates, it's a big deal. 🧵 ...

HBOT ranks as one of the highest value health therapies I’ve done. Results from 60 sessions: + wiped out all systematic inflammation in my body. Below detectable levels. This is wild. + 300% increase in VEGF (formation of new blood vessels) + telomerase activity of a 12 year old, associated with b...

Glass had 5 – 50× higher plastic than plastic or cans The French tested water, soda, beer, iced tea, lemonade, and wine sold nationwide and found that glass-bottled beverages carried far more plastic shrapnel than plastic bottles or cans. 🧵...

A new study is out: things that make you age faster, and slower, according to 16 epigenetic age clocks. 🧵 ...
