34, chef, on my feet 12+ hours. Did 300 mcg sermorelin before bed, 5 nights on, 2 off, for 12 weeks. By week 3 sleep was deeper and I stopped waking at 3am. Body fat went from 18% to about 15.5%, lost 6 lbs while keeping my lifts the same. Double shifts felt less brutal. IGF-1 labs went 148 to 196 ng/mL. Side effects: mild redness at injection sites and crazy dreams for the first 10 days, then fine. Not cheap, and results are gradual. I'd run it again.
Ran 200 mcg subQ before bed, 5 nights on and 2 off, for about 12 weeks. I'm 43 and work in a warehouse, so recovery matters. Sleep improved around week 3—deeper, fewer wake-ups. Soreness after loading trucks dropped. Lost 6 lbs and about 1.5 inches off my waist while eating about the same. Bench went up 10 lbs. Side effects: mild flush and head rush for 10 minutes after injecting, odd vivid dreams, and some morning grogginess if I pinned late. Cost was around $180 a month. Not dramatic, but steady enough to continue.
I ran sermorelin at 200 mcg before bed, five nights a week, for about four months. First two weeks nothing, then around week three I started sleeping straight through — I used to wake up three or four times a night. Morning stiffness in my hands eased off too. Dropped about 6 lbs without changing my diet much, mostly around the waist. Only real downside was flushing and a head rush right after pinning, gone in 20 minutes. Site got sore if I didn't rotate. Not cheap, roughly $200 a month, but I'd run it again.
28-year-old accountant here. Ran 200 mcg subq before bed, 5 nights on/2 off, for about 12 weeks. Sleep got way better by week 3—falling asleep faster, vivid dreams, waking up less. Recovery from lifting improved, and I leaned out maybe 3-4 lbs while staying around 176. IGF-1 labs went from 168 to 205. No major sides, just occasional injection site redness and a mild headache first week. Muscle gains weren't dramatic; this is subtle stuff. Cost adds up, but I'd use it again for sleep and recovery.
I'm 45 and on my feet cutting hair all day. Started sermorelin at 300 mcg before bed, 5 nights on, 2 off, for about 3 months. First week I got mild headaches and some redness at the pin site, nothing major. Sleep got deeper by week 3, vivid dreams, and I wake up less. Recovery after gym is better. Lost about 4 lbs and an inch off my waist, but diet was also decent. No huge muscle gains. It's pricey, but I renewed. Just don't expect a miracle.
I’m 41 and home with the kids all day, so sleep matters. I started sermorelin at 200 mcg before bed, 5 nights on/2 off, for about 14 weeks. Sleep got deeper by week 3, and morning energy is better. Waist dropped about 1.5 inches, scale down 6 lbs, while diet/training stayed mostly the same. Muscles feel a bit fuller. Side effects: occasional vivid dreams and slight injection-site redness. IGF-1 labs went from 118 to 162. Not dramatic, but steady. Not cheap, but for me it’s been worth it.
I’m 36, work as an accountant, so desk job and stress mess with sleep. Ran sermorelin at 300 mcg subq before bed, 5 nights on/2 off, for 12 weeks. IGF-1 went from 178 to 236. Sleep was the big one, deeper and I wake up less. Recovery after lifting felt better, and I dropped about 4 lbs while staying same strength. Waist down roughly an inch. Side effects: mild injection site redness a few times, vivid dreams, occasional headache first week. No major issues. It’s not dramatic, but consistent. Cost adds up, so I’d rate value decent.
41-year-old chef here, on my feet 10-12 hours a day. I ran sermorelin at 200 mcg subQ before bed, 5 nights on, 2 off, for 12 weeks. By week 3 sleep was noticeably deeper; I wake before my alarm and don't crash after double shifts. IGF-1 went from 142 to 188 at 8 weeks. Waist down about 1 inch, weight down 3-4 lbs without changing much diet. Side effects: vivid dreams early on, mild injection-site redness, one headache. Strength held while I cut carbs. Not a miracle, but I'd use it again if pricing improves.
I’m a 45-year-old PT and ran sermorelin at 200 mcg subQ before bed, 5 nights on/2 off, for 12 weeks. First week I got mild injection-site redness and weird vivid dreams. By week 6 sleep went from 5–6 broken hours to 7–7.5, waking maybe once instead of three times. IGF-1 bloodwork went 150 to 185. I dropped 4 lb and an inch off my waist while keeping my lifting numbers the same. No numbness or blood sugar issues. Skin seemed a bit fresher but hard to say. It’s not cheap, but I’ll likely run it again this winter.

I'm 29 and I turn wrenches for a living. My doctor put me on sermorelin. Tbh the FDA-approved part made me feel better about it, and imo it's better than just pinning straight GH because it keeps your body's own feedback loop working like it should. It's for anti-aging stuff and you gotta be under a doctor's watch. Not gonna lie, the results are gradual, you don't wake up jacked or anything, but they are real. I didn't really have side effects besides maybe sleeping a bit better? Anyway, I'd say it's legit if you're patient.
