My Bodybuilding Experience on Finasteride, Muscle Building, Gyno, Fat Loss, Strength!

Key takeaways from the video (finasteride experience + performance/body composition)

Gynecomastia check & hormone testing

• Gynecomastia is described as potentially resulting from a testosterone/estrogen imbalance and estrogen receptor sensitivity in breast tissue.
• The presenter reports no gynecomastia during his oral finasteride use.
• He states he completed baseline and follow-up bloodwork:
  • Testosterone: ~850 ng/dL at baseline, and reported slightly higher after 4 months (with additional specific values also mentioned).
  • Estradiol (E2): reported to decrease modestly, while staying within a reference/healthy range.

Fat loss / weight loss

• His claim: finasteride is unlikely to meaningfully affect fat loss because it would need to alter:
  • Resting metabolic rate
  • Thermic effect of feeding
  • Thermic effect of exercise
• He reports that his ability to lose body fat/weight felt the same on finasteride as before.

Body fat target & training implications

• He prefers staying around ~10–15% body fat year-round.
• He avoids prolonged single-digit body fat because he believes it can reduce muscle retention/building for him, as a “natural athlete” focused on maximizing hypertrophy and aesthetics.

Muscle building potential

• He argues it’s hard to determine finasteride’s effect on muscle growth because:
  • After 10+ years of training, his “remaining muscle-building potential” is likely <10%.
• Research he cites includes:
  • DHT suppression (via dutasteride) did not reduce lean mass gains when testosterone doses were manipulated—suggesting testosterone’s anabolic role is primary.
  • In a genetic scenario involving 5-alpha-reductase deficiency (lower/no DHT), the affected person was described as more muscular than the twin with normal DHT production.

Strength and gym performance

• He reports continuing to progress strength by following the right workout regimen and progressive overload, even while on finasteride.
• He states any strength impact would have been noticeable to him due to 10+ years of training experience.

Wellness / productivity / self-care strategies mentioned (training + recovery approach)

Training style to protect joints while building aesthetics

• He avoids heavy powerlifting-style loading due to:
  • Family history of knee/joint issues
  • His own surgery at age 16
• He uses hypertrophy-focused programming, typically:
  • 6–15 reps, sometimes 15+
  • Higher frequency (training specific body parts more often per week)
• Goal: prioritize muscle growth, aesthetics, mobility, and reduce injury risk.

Progress tracking

• He emphasizes that strength progression is driven by:
  • tracking progress
  • progressive overload
  • using the right regimen (tailored to his goals and injury risk)
