For bodybuilding purposes, the recommended sermorelin dosage starts at 0.2 to 0.3 mg per day. This is considered the beginning dose for most people.
After your body adjusts, you can increase to a maintenance dose of 0.4 to 0.5 mg daily, depending on how you respond.
Most bodybuilders inject sermorelin once daily before bedtime. This timing works best because it matches your body's natural growth hormone release patterns during sleep.

Starting at the lower dose (0.2 mg) is smart. You can slowly increase if needed while watching for any side effects. Taking too little won't give you the muscle gains you want, but taking too much might cause unnecessary side effects without extra benefits.
Sermorelin works best when combined with proper training and nutrition. If you're serious about maximizing your muscle growth, you might want to check out other muscle growth peptides that can complement your sermorelin use.
