Proprietary Extract Blend
Also known as: LI12542F6, proprietary extract blend, Sphaeranthus indicus extract, Mangifera indica extract
Overview
LI12542F6 is a proprietary extract blend formulated to enhance athletic performance, particularly in terms of muscle strength and endurance. It primarily consists of Sphaeranthus indicus, recognized for its muscle-enhancing effects, and Mangifera indica, which offers various health benefits. Initial clinical trials of up to 56 days have shown significant improvements in physical fitness outcomes, such as increases in mid-upper arm circumference and elevated testosterone levels in young, healthy males. Available in capsule and tablet forms, LI12542F6 displays promising potential, but further investigation, particularly through randomized controlled trials, is necessary to optimize ingredient ratios and assess effectiveness across diverse populations.
Benefits
LI12542F6 has demonstrated significant benefits for young, active males aiming to improve muscle strength and endurance. Clinical trial findings report substantial performance enhancements, with p-values indicating a strong correlation between supplementation and increased mid-upper arm circumference (< 0.0001) and testosterone levels (< 0.0008). These findings present robust evidence supporting its efficacy in boosting athletic performance. Further research is warranted to evaluate long-term benefits and potential effectiveness in broader demographics, including older adults and individuals with specific health challenges.
How it works
The mechanism of action for LI12542F6 involves enhancing muscle protein synthesis and activating metabolic pathways crucial for hypertrophy. The primary ingredients facilitate hormonal changes resulting in increased testosterone levels, which are essential for muscle recovery and growth following exercise. This elevation of hormonal activity contributes significantly to the blend's effectiveness in enhancing athletic performance.
Side effects
LI12542F6 is generally well tolerated, with clinical trials reporting adverse effects in fewer than 1% of participants; over 5% of users experienced no side effects at all. Users taking concurrent medications should exercise caution, as existing literature on interactions remains sparse. Pregnant or nursing women, children, seniors, and individuals with pre-existing health conditions should seek medical advice before using this supplement. Although positive safety data is available, it is crucial to monitor individual reactions due to variability among users.
Dosage
The recommended daily dosage for LI12542F6 is approximately 650 mg, with an emphasis on consistent intake to achieve optimal results. While specific timing for supplementation has not been definitively established, maintaining a regular dosing schedule is advisable to enhance the absorption of active components. Currently, there are no defined upper limits or safety thresholds, underscoring the importance of adhering to the suggested dosage to ensure both safety and efficacy.
