Early generation SARM. Development discontinued by GTx due to vision-related side effects observed in human volunteers — a yellow tint to vision and difficulty adapting to low-light conditions.

Side Effects & Risks

Performance Use

Andarine was an early-generation SARM that attracted attention for producing lean hard muscle with strength increases and a dry appearance. Its development was discontinued specifically because of vision side effects in human volunteers, which reduced its adoption relative to later SARMs. In performance use it appears in cutting phases and recompos...

Stacking & Combinations

Andarine has limited stacking use in current performance settings because its development was discontinued and later SARMs offer comparable effects without the vision risk. When it does appear in stacks it functions similarly to Masteron or Stanozolol in terms of its role, adding hardness and a dry visual effect to an existing base. It is sometimes...

Real-World Risk

The vision disturbance that Andarine causes is not a rare or individual reaction. It is a class effect related to androgen receptor binding in the retina. It presents as a yellow tint to vision and difficulty adjusting to low light, particularly when moving from bright to dark environments. While th...
