[QUOTE="Nelson Vergel, post: 259000, member: 3"] [MEDIA=youtube]Jq0hf8f6b70[/MEDIA] Nelson Vergel, reviews a research paper from 2001 by Dr. Bhasin, a leading researcher on testosterone and androgens. The study looked at the effects of different doses of testosterone on various parameters in young men, including hormones, strength, and sexual function. Key points discussed in the video include: [LIST=1] [*]The study involved about 65 healthy young men (average age 25), whose natural testosterone was blocked and were then given varying doses of testosterone cypionate injections (25mg, 50mg, 125mg, 300mg, and 600mg) weekly for 20 weeks. [*]The participants were asked not to go to the gym or workout for the study duration to evaluate the effects of the testosterone doses. [*]Testosterone levels at baseline were healthy (500s-600s). As the testosterone dose increased, total and free testosterone levels also increased. [*]With 125mg per week, the testosterone level was almost back to the baseline. With 300-600mg per week, it went into the 1300s or 2300 nanograms per deciliter. [*] As testosterone dose increased, sex hormone binding globulin decreased significantly by 300mg and 600mg doses. IGF-1, a metabolite of growth hormone in the liver, increased significantly at higher doses (300-600mg per week). F [*]at-free mass (lean mass and water retention) significantly improved at 125mg or more per week. Fat mass decreased with testosterone, particularly at 125mg or more per week. [*]Measurements of thigh muscle volume by MRI showed significant improvement at 125mg and above. [*]Sexual activity and intensity of sexual desire did not change significantly across all doses. [*]Cognition did not change significantly with any of the doses. Leg press strength and power significantly increased at the 300 and 600mg doses. [*]Higher testosterone doses increased hemoglobin and red blood cells but decreased HDL (good cholesterol). [/LIST] In conclusion, Vergel mentions the need for further studies to determine optimal testosterone dosage, given the trade-offs in effects on strength, sexual activity, cognition, and cardiovascular risks. He also notes that these results may not generalize to populations that are older, overweight, or physically active. [/QUOTE]
