A 2006 study examined the impact of high-dose clenbuterol on cardiac and skeletal muscle function in patients with heart failure supported by left ventricular assist devices (LVADs). PubMed Study Overview: - Participants: Seven heart failure patients (five ischemic, two non-ischemic) on LVAD support. - Intervention: Oral clenbuterol, titrated up to 720 mcg daily, administered for three months. - Assessments: Echocardiography, cardiopulmonary exercise testing, body composition analysis, and quadriceps maximal voluntary contraction (MVC) measured at baseline and after three months. Key Findings: Cardiac Function: - No improvement in ejection fraction. - Significant increase in end-diastolic dimension (from 4.73 ± 0.67 cm to 5.24 ± 0.66 cm; p < 0.01). - Trend toward increased left ventricular mass. Skeletal Muscle: - Significant increases in body weight and lean mass. - MVC improved significantly (from 37.0 ± 15.7 kg to 45.8 ± 20.6 kg; p < 0.05). Safety: - No serious adverse events or arrhythmias reported. - Elevated creatine phosphokinase (CPK) levels in four subjects, without clinical consequences. Conclusion: High-dose clenbuterol did not enhance cardiac function in LVAD-supported heart failure patients. However, it increased skeletal muscle mass and strength, counteracting the typical decline in myocyte size during LVAD support. These findings suggest clenbuterol's potential to aid skeletal muscle recovery, though its effect on cardiac function remains unproven. PubMed Implications for Bodybuilders: While clenbuterol is sometimes used off-label to increase muscle mass and strength, this study indicates that its benefits may be limited to skeletal muscle, with no positive but no real negative impact on cardiac function within 3 months of use. The potential for elevated CPK levels suggests a need for caution due to possible muscle damage.

Assuming the goal is fat loss, 200mg is a perfectly effective dose when following a polypharmacy model with multiple drug pathways contributing to the desired end result. Although this is not what I would recommend, you’d likely need more than that to see noticeable effect if using L-Carnitine alone. 200mg of l-carnitine + 1.5iu of GH for example would be a great synergy of FFA mobilisation + transport. For fat loss I would simply recommend remaining fasted for the duration of time you want to accelerate the transportation of mobilised fatty acids. So for example, the duration of your fasted cardio, or the 2-3 hour window that GH will be mobilising FFA’s for. For hypertrophy, dosages at >1000mg potentially cause issues with FFA dumping, so I wouldn’t recommend going that high. I don’t see issues with 200-600mg/day, but I have never seen a case for nutrient transport that has warranted >200mg in my experience. Pre-workout to aid in glucose disposal is smart idea.

A recent systematic review titled "Which ROMs Lead to Rome? A Systematic Review of the Effects of Range of Motion on Muscle Hypertrophy" examines how different ranges of motion (ROM) during resistance training impact muscle growth. Key Findings: Full ROM (fROM): Training with a full range of motion generally promotes greater hypertrophy in muscles like the gluteus maximus and adductors compared to partial ROM (pROM) performed in the latter part of the movement. Partial ROM at Longer Muscle Lengths: Executing pROM in the initial phase of the movement—where the muscle is elongated—can lead to significant growth in specific muscles: - Quadriceps Femoris: Notable hypertrophy observed when training at longer muscle lengths. - Biceps Brachii and Triceps Brachii: Enhanced growth achieved through pROM in the initial part of the movement. Muscle-Specific Responses: The effectiveness of fROM versus pROM varies by muscle group. For instance, pROM in the middle portion of the movement elicited greater triceps brachii hypertrophy than fROM Practical Implications: - Incorporate Both ROMs: Combining fROM with pROM, especially at longer muscle lengths, can optimize hypertrophy across different muscles. - Tailor to Muscle Groups: Customize ROM strategies based on the target muscle to maximize growth. Considerations: - Training Experience: The studies reviewed included both trained and untrained individuals; responses may differ based on training history. - Exercise Selection: The type of exercise and equipment used can influence the effectiveness of ROM variations. In summary, this review underscores the importance of strategic ROM application in resistance training to enhance muscle hypertrophy. Integrating both full and partial ROM exercises, with attention to muscle length during training, can provide a more comprehensive approach to muscle development.

Clomid, is an oral medication most commonly prescribed as a fertility drug. It’s classified as a selective estrogen receptor modulator or SERM, meaning it doesn’t directly alter hormone levels but instead works by blocking estrogen receptor sites. This gives the body the false impression that estrogen levels are low, triggering the pituitary gland to increase luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones then signal the testicles to produce more testosterone. This mechanism can be effective for specific situations, such as secondary hypogonadism caused by pituitary dysfunction or when fertility is the goal. However, Clomid’s ability to artificially stimulate testosterone production comes with significant drawbacks when used outside of these scenarios, especially as a long-term replacement therapy. Men often report a rapid increase in testosterone levels during the early stages of Clomid use. But within months, issues like mood swings, depression, diminished libido, weight gain, and other estradiol-related metabolic problems tend to appear. These side effects occur because while estrogen levels may be sufficient in the bloodstream, Clomid blocks estrogen’s ability to act on its target tissues. The result is a mismatch between hormonal balance and physiological function—similar to having money in the bank but no access to spend it. It can even result in vision issues, including floaters and, in rare cases, farsightedness, have been reported. These effects occur because estradiol also plays a role in the health of the optic nerve and retina. Blocking estrogen receptors in these areas can lead to visual disturbances, particularly with prolonged use or higher doses. Bodybuilders often use it after steroid cycles to reignite the hypothalamic-pituitary-testicular axis (HPTA), restoring natural testosterone production. While effective in this context, reliance on PCT and frequent cycling can eventually damage the pituitary gland.
