Episode Summary
Executive Summary: Peter Atiyah interviews Derek of More Plates, More Dates about bodybuilding pharmacology, focusing on growth hormone, peptides, testosterone, fertility, hair loss, and anabolic steroids. The conversation blends Derek’s personal experience with underground bodybuilding culture and clinical nuance, emphasizing that many compounds are widely used but poorly studied, so dosing, monitoring, and risk assessment matter greatly.
Main Topics: Derek’s background and entry into bodybuilding pharmacology (Priority: 5/5): Derek describes starting lifting in high school, rapidly becoming immersed in forums, hormones, and bodybuilding culture, and eventually building a career around online education and analysis. Growth hormone physiology, dosing, and real-world use (Priority: 5/5): The discussion covers GH’s role in growth, lipolysis, IGF-1, feedback loops, dosing strategies, and why its benefits in adults are uncertain outside narrow medical uses. Peptides and GH secretagogues (Priority: 4/5): They compare GHRP/GHRH compounds such as ipamorelin, tesamorelin, sermorelin, CJC-1295, and MK-677, including appetite effects, clinic use, and the logic of stacking. Anabolic steroids, bodybuilding, and physique evolution (Priority: 5/5): The speakers contrast 1970s and modern bodybuilding, arguing that drug escalation—especially GH and insulin—drove much of the change in size, while nutrition and training also evolved. Testosterone, estradiol, DHT, and TRT optimization (Priority: 5/5): They review the HPT axis, androgen/estrogen balance, assay limitations, dosing frequency, and why more physiologic injection schedules may reduce side effects. Fertility preservation and recovery after suppression (Priority: 4/5): The conversation compares HCG, Clomid, and recombinant FSH, stressing that maintaining intratesticular testosterone and testicular function improves recovery odds. Hair loss, 5-alpha reductase inhibitors, and antiandrogens (Priority: 4/5): Derek explains his own hair-loss salvage strategy and discusses finasteride, dutasteride, topical antiandrogens, and the tradeoffs of suppressing DHT.
Key Arguments: Growth hormone is often marketed as a longevity elixir, but evidence for broad adult benefit is weak; its clearest effects are on lipolysis, IGF-1, and some recovery contexts. Bodybuilders provide unusually useful anecdotal data because they use compounds at high doses and observe effects closely, but their experiences are still not substitutes for controlled trials. Exogenous GH suppresses endogenous GH through IGF-1/somatostatin feedback, but the pituitary appears more recoverable than the gonadal axis after long-term suppression. More frequent testosterone dosing better mimics physiologic rhythms, reduces peaks, and may lower aromatization, DHT spikes, and side effects compared with weekly bolus injections. Estrogen is not the enemy in men; overly suppressing estradiol can worsen mood, bone health, cardiovascular risk, and possibly neuroprotection. For fertility, maintaining intratesticular androgen signaling is crucial; HCG is often more useful than Clomid for preserving testicular function during TRT or steroid use. Hair-loss treatment is a tradeoff: DHT suppression can help preserve hair, but systemic antiandrogen effects may carry sexual or endocrine risks. Modern bodybuilding physiques likely reflect a combination of more aggressive drug use, better nutrition, and improved training, with drugs being the biggest driver of the size shift.
Data Points: Derek’s peak bodyweight: 260+ pounds - He reached this size in university during his heaviest bodybuilding phase and developed sleep apnea. Peak anabolic exposure: 1,500 mg to 2 g per week - Derek described his highest combined weekly anabolic steroid exposure as far above physiologic TRT. Typical TRT dose cited by Peter: up to 150 mg testosterone cypionate/week - Used as a comparison to show how supraphysiologic Derek’s bodybuilding doses were. Growth hormone use: 6 to 8 IU daily - Derek said this was his highest acute GH dose, used only briefly. Common GH bodybuilding dose: 1 to 2 IU/day - Peter referenced this as a typical longevity/clinic-style dose. Testosterone decline with age: ~1% total T/year and ~2% to 3% free T/year - Derek summarized general literature on age-related testosterone decline. HGH half-life / steady state: ~10 days half-life; ~50 days to steady state - Discussed in relation to testosterone cypionate pharmacokinetics and injection frequency. HCG fertility maintenance example: 375 IU every other day - Approximate bodybuilding dose mentioned for maintaining intratesticular testosterone while suppressed. HCG study dose: 4,000 IU - Referenced as a study dose used to examine suppression and response in men with normal gonadal function. Estradiol assay discrepancy: 100 vs 31 pg/mL - Peter described a case where enzyme-based testing read 100, but LC-MS showed 31. Bodybuilder heart weights: 660 g and 860 g - Examples cited for Rich Piana and Dallas McCarver to illustrate severe cardiac enlargement in some deceased bodybuilders. DHT suppression with finasteride: ~70% systemic reduction - Peter and Derek discussed Proscar/finasteride effects on DHT and downstream testosterone/estradiol changes. Testosterone increase after 5-alpha reductase inhibition: ~15% to 22% - Derek noted that blocking DHT conversion can raise testosterone and estradiol modestly. IGF-1 response to MK-677: 200 to 300 range - Derek said oral secretagogues can raise low IGF-1 into the high-normal range. Bodybuilder daily food intake: 5,000 calories/day or more - Used to explain abdominal distension and the demands of maintaining very large physiques. Daily testosterone microdosing example: 15 mg/day - Peter described a patient regimen that reduced aromatase inhibitor need versus weekly dosing.
Pivotal Quotes: "There is a severe diminishing returns as you escalate for sure." — Derek: On why higher anabolic steroid doses do not produce proportionally higher results. "The closest you can replicate natural function, the more you will replicate natural side effect profiles." — Derek: On why frequent, smaller testosterone doses may be better tolerated than weekly boluses. "Estrogen is not the bad guy." — Peter Atiyah: Summarizing the study and broader point that men need some estradiol for health and function.
Implications: Listeners should view bodybuilding drugs as powerful but context-dependent tools, not magic bullets. For clinicians and consumers, the key lessons are careful monitoring, physiologic dosing when possible, and skepticism toward simplistic claims about GH, TRT, or anti-aging protocols.
