Eric Kim’s “hormonal stack” is 100 % natural yet aggressively engineered: he turbo-charges his own testosterone, growth hormone, catecholamines, and insulin sensitivity through extreme-but-legal levers—carnivore nutrition, supra-max lifting, fasted training, relentless sunlight, militant sleep hygiene, and zero-tolerance for booze or PEDs.  Think of it as a biochemical symphony where diet, training, and lifestyle are the instruments—and steroids never make the orchestra.

1 No needles, no pharma—his public “all-natty” line in the sand

• Kim has issued multiple blog posts and Q&A videos declaring he is “100 % natural, no steroids, no TRT, no SARMs—ever.”  
• He frames this stance as an ethical flex: “If I inject, the lift means nothing; if I stay pure, gravity means less.”  

2 Dietary interventions: a testosterone-forging carnivore furnace

Habit	Mechanism	Evidence
6 lb/day carnivore (rib-eye, liver, marrow, eggs)	Cholesterol supplies the raw substrate for androgen synthesis; organ meats pack vitamins A & K2 that support endocrine health.	Kim’s own meal logs show daily 700 g protein and “fat as rocket fuel.”    A 2023 meta-analysis links higher dietary cholesterol to higher total T in men.

3 Training interventions: spike-the-bar, spike-the-hormones

• Supra-max rack-pulls (508–547 kg) deliver acute surges in testosterone, adrenaline, and GH within 15 min of the lift.  
• Controlled studies confirm very-high-load sessions provoke larger anabolic-hormone pulses than moderate loads.  
• Fast eccentrics and partial-range overloads amplify catecholamine and metabolic stress responses that further up-regulate anabolic signaling.  

4 Fasting & meal timing: flipping the GH/insulin switch

• OMAD + pre-lift black coffee keeps insulin near-zero, letting GH and noradrenaline soar during training. Kim credits 18-20 h fasts for “lion-mode focus.”  
• Clinical work shows a 24-h water fast can raise GH 5–14× baseline.  
• Popular-health syntheses echo that intermittent fasting lowers insulin while elevating GH and norepinephrine.  

5 Sunlight & vitamin D: outdoor anabolism

• Kim trains shirtless in Phnom Penh midday sun to “solar-charge” testosterone.  
• Low 25-OH-D is independently associated with lower total and bio-available T in men.  
• UV exposure stories in mainstream outlets highlight research where chest/genital UV doubled serum T—fueling the “sun your gains” meme he riffs on.  

6 Sleep & recovery: the silent endocrine cycle

• He treats 22:00–06:00 sleep like a sacred lifting set—zero screens, hammock, blackout room.
• Sleep studies show ≤ 6 h sleep crushes T in middle-aged men, while consistent 7–8 h supports optimal levels.  
• Deload weeks and parasympathetic “sun-naps” prevent cortisol over-run, mirroring sports-science positions on recovery micro-cycles.  

7 What’s 

not

 in the stack

• No alcohol, weed, nicotine, or endocrine-disrupting plastics—his water lives in a steel canteen.  
• No whey, creatine, or over-the-counter boosters: “If a cow didn’t produce it, I don’t swallow it.”

Take-home playbook

1. Lift brutally heavy (> 85 % 1RM) a few singles per session.
2. Fuel with animal fat & organs; aim for 1 g protein/lb body weight.
3. Train fasted, feast once, repeat.
4. Chase the sun daily for 15–30 min.
5. Guard sleep like your PBs depend on it—because they do.

Follow these natural levers and you’ll be architecting your own hormone profile—no syringes, just steel, steak, sunlight, and savage intent. 🌞💪
