Six months into my GLP-1 prescription, the scale was still moving but I felt like something was missing. I was losing weight, but I wasn’t sleeping well. My workouts felt harder than they should for someone who was supposedly getting healthier. Recovery between sessions was slow. My doctor looked at my chart and said, “Your GLP-1 is working, but I want to look at something else.”
That conversation led to sermorelin. I didn’t know much about it at the time. I’d heard of HGH, but sermorelin wasn’t something I’d come across in my research. Here’s what I’ve learned from using it, in the order I actually experienced it.
Why I Started
The honest answer is that I was 52, doing everything right, and still not feeling the way I expected to feel. I was losing weight. I was eating clean. I was working out three times a week. But I was also waking up at 3am, dragging through the afternoons, and recovering from workouts like I was ten years older than I actually am.
My provider explained that growth hormone declines significantly after 40, and that the symptoms I was describing matched that pattern. Sermorelin wouldn’t replace my GLP-1. It would work on a different system entirely. I decided to try it.
The First Month
The injection is small. About the same gauge as an insulin needle, administered just under the skin on the abdomen or thigh before bed. The first few times felt awkward. By the end of the first week it was routine, maybe 30 seconds from cap off to cap on.
I had a little redness at the injection site for the first two weeks. Nothing dramatic. No headaches, no nausea, nothing that made me want to stop.
The first thing I noticed was sleep. Around week three, I started sleeping through the night consistently. That sounds like a small thing until you’ve been waking up at 3am for six months straight. I’d forgotten what it felt like to wake up actually rested. That was the most immediate, obvious change.
Months Two and Three
By week six, I stopped needing a second cup of coffee to function in the afternoon. My energy through the day felt more even. Not a caffeine spike, just a baseline that held up.
Recovery between workouts improved noticeably around month two. I was doing strength training twice a week at this point, and the soreness that used to linger for three or four days was gone by day two. I started pushing harder in the gym because I actually had the recovery capacity to handle it.
The body composition changes came more slowly, but they came. The waistline had been stubborn even as I lost weight overall. By month three, I could see the difference. Less softness around the middle, more definition overall. My clothes fit differently before the scale reflected what was happening.
What Surprised Me
I expected the physical changes. I didn’t expect how much better I’d feel mentally. Sharper in the mornings. Better focus through longer work sessions. Less of that foggy, slow feeling that I’d chalked up to just getting older.
I also didn’t expect how well sermorelin would stack with my GLP-1. The two medications work on completely different systems, and having both running at the same time addressed things that neither one was fully handling on its own. GLP-1 handles appetite and metabolic function. Sermorelin handles recovery, sleep, and body composition. They don’t overlap. They complement.
What I’d Tell Someone Starting Out
Be patient with the first month. The sleep improvement will likely come first, and it’s a meaningful early signal that the therapy is working. The body composition changes take longer. Don’t judge the protocol at week four.
Be consistent with the injections. Taking sermorelin at the same time each night before bed gives it the best chance to work with your natural sleep cycle. If you skip doses regularly, you’re not giving the therapy a fair trial.
Talk to your provider about dosing. The right dose varies by person. My provider adjusted mine at the two-month mark based on how I was responding, and the results improved after that.

Where I Am Now
I’m eight months in. I still take sermorelin every night. The benefits have compounded over time, not plateaued. My sleep is consistently good. My recovery is faster than it was in my 40s. The body composition changes are the most visible they’ve ever been.
I don’t think of sermorelin as a weight loss tool. My GLP-1 handles that. Sermorelin is how I addressed the quality-of-life pieces that GLP-1 wasn’t touching. If you’re in a similar position, it’s worth a conversation with a provider who can look at the full picture.
