Does injecting tertesteron workfor creating muscle mass in men over 70
Executive summary
Injecting testosterone (the user wrote “tertesteron”; available sources treat testosterone therapies) in older men has repeatedly been shown to increase lean mass—meta-analyses and randomized trials report average gains of about 1–4 kg of lean mass and consistent decreases in fat mass [1] [2] [3]. However, effects on muscle strength and real-world physical performance are inconsistent across trials, and higher doses raise the risk of adverse effects [3] [4].
1. What the trials show: more muscle mass, mixed functional benefit
Multiple randomized controlled trials and meta-analyses report that testosterone replacement increases lean body mass in older men: a meta-analysis found mean lean-mass gains with high heterogeneity and an effect estimate of about +3.6 kg across studies (range ~1.6–6.2 kg) [1]. Long-term randomized trials also reported greater lean mass and some improvements in muscle power or strength measures—e.g., a 3‑year trial in men ≥60 found significant increases in chest-press strength and leg-press power and an increase in lean body mass for the testosterone group [2]. Yet several large trials and reviews emphasize inconsistent or modest effects on physical performance measures such as walking speed or overall functional status [3] [5].
2. Older men remain responsive but risks grow with dose
Controlled dose–response studies show older men are as responsive as younger men to testosterone’s anabolic effects: graded testosterone raised fat‑free mass and strength in older men, producing substantial gains at higher (often supraphysiological) doses [4]. Those larger gains, however, were accompanied by more frequent adverse effects—older men had greater hemoglobin increases and higher adverse‑event rates at high doses [4]. Sources consistently caution that benefits must be weighed against risks, especially when targeting supraphysiological levels [4] [3].
3. How much improvement to expect and what matters
Expect modest increases in lean mass in clinical trials—often 1–4 kg depending on dose, duration, baseline testosterone, and method of administration (injectable, transdermal) [1] [6]. Improvements in measured muscle strength or power are less consistent and depend on trial length and which outcomes were tested; some trials show increased strength or power, others show little change in functional endpoints [2] [3]. Combining resistance exercise with testosterone tends to produce larger or more functionally meaningful results in middle‑aged and older men, per comparative analyses [7].
4. Clinical indications, diagnosis, and practical considerations
Most trials enrolled men with low or low‑normal testosterone and/or symptoms of hypogonadism; guidelines and trials typically require documented low serum testosterone before treatment [2] [3]. Available sources emphasize treating hypogonadism rather than “anti‑aging” off‑label use and note variable trial inclusion criteria, so results may not generalize to all men over 70 [3] [7]. Sources do not provide a protocol for unsupervised “injecting” of testosterone; medical supervision and monitoring are standard in trials [2] [4].
5. Safety, monitoring, and unanswered questions
Trials and reviews flag potential harms (hematocrit rises, prostate concerns, cardiovascular signals at times) and note inconsistent evidence on whether testosterone reduces important clinical outcomes like falls or disability [4] [3]. Long‑term safety remains an area of active study and debate; randomized evidence shows body‑composition benefits but inconsistent functional benefits and unresolved questions about net clinical benefit versus risk [3] [5].
6. How to weigh options: alternatives and combined strategies
Exercise—especially resistance training—consistently increases lean mass and improves strength across ages; short resistance programs commonly yield ~1.3 kg lean mass gains in men 50–76 and are effective adjuncts to or sometimes substitutes for hormonal therapy [7]. Nutrition (adequate protein) and targeted exercise should be part of any plan to counter sarcopenia; several reviews recommend combining lifestyle interventions with medical therapy when appropriate [8] [7].
7. Bottom line for a man over 70 considering injections
Injectable testosterone can increase lean mass in men over 70 and may improve some strength or power measures, but functional benefits are inconsistent and risks rise with higher doses—medical evaluation, baseline testosterone testing, and supervised treatment with monitoring are essential [1] [4] [3]. Available sources do not provide guidance for unsupervised or recreational "injecting" and do not support use without documented low testosterone and clinician oversight [2] [3].
Limitations: reporting varies by trial population, dose, route, and outcomes; heterogeneity among studies is high and long‑term effects on disability, falls, and mortality remain incompletely resolved [1] [3].
