The potential benefits of a beginner's first steroid cycle include significant gains in muscle mass and strength, even with limited knowledge of steroids, nutrition, and training. A dosage of 300-500mg of testosterone per week for 8-12 weeks can produce noticeable enhancements in muscle mass and performance. However, the potential risks associated with steroid use include liver damage, cardiovascular issues, hormonal imbalances, and negative impacts on mental health. Beginners should be aware of the potential side effects and take steps to mitigate them through proper dosing, cycle length, and post-cycle therapy. Additionally, beginners should carefully consider the legal and ethical implications of using steroids and consult with a medical professional before starting any steroid cycle.
