- Both peptides and SARMs are researched for their muscle-building capabilities. However, their approaches to promoting muscle growth vary. Peptides work by increasing natural HGH levels, which indirectly supports muscle development. In contrast, SARMs were simply designed to promote androgenic activity in the body by directly stimulating androgen receptors. Here are clinical trials that confirm their muscle-building potential:
- A phase 2 clinical trial investigated the effects of Ostarine on muscle growth in elderly men. The trial involved 120 participants who took 3mg of Ostarine daily for 12 weeks. Results showed an average lean body mass gain of 2.9 pounds compared to placebo. [10]
- A phase 1 clinical trial examined the impact of Ligandrol on muscle mass in young men. The study included 76 participants who took 1mg of Ligandrol daily for 3 weeks. Results indicated an average lean muscle mass increase of 2.64 pounds. [11]
- However, peptides have also shown a potential to improve muscle growth:
- One study suggests that Ipamorelin, a growth hormone secretagogue (GHS), can help with muscle growth. The research found that in an adult rat model, Ipamorelin counteracted the catabolic effects of glucocorticoid (GC) on skeletal muscles and bone. When used in combination with GC, Ipamorelin significantly increased the maximum tetanic tension of the calf muscles and improved bone formation. [12]
- Another study highlights the potential of CJC-1295, a long-acting GHRH analog, to enhance muscle growth by increasing growth hormone (GH) and IGF-I levels. The results showed that a single injection of CJC-1295 led to significant, dose-dependent increases in GH concentrations, which lasted for at least 6 days, and IGF-I concentrations, which remained elevated for 9-11 days. Over multiple doses, IGF-I levels stayed above baseline for up to 28 days, indicating a sustained effect that could support muscle growth over time. [13]
