Sermorelin Before and After: What Changes, and When
Sermorelin before and after: what clinical studies measured at 2, 6 and 16 weeks, what our four anonymous reports describe, and why photos mislead. Not medical advice.

Short answer
Most sermorelin "before and after" pictures online come from clinics selling a programme, usually alongside diet, training or testosterone. The controlled studies tell a quieter story: sermorelin and close GHRH analogues reliably raise growth hormone, IGF-1 usually rises within weeks, and the visible changes that were measured (skin thickness, lean mass in men, a few strength tests) were small. In those trials weight and body fat did not change. Our own archive has four sermorelin confessions, and none describes a physical before-and-after. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.
Timeline: what studies actually measured
These are the main human studies of sermorelin (GHRH 1-29) or a closely related analogue. They were small, mostly in older adults, and from the 1990s. Doses are deliberately left out. Last reviewed October 17, 2026.
| Time point | What changed | What did not | Study |
|---|---|---|---|
| Minutes to hours | A burst of growth hormone after each injection, lasting about two hours | Nothing visible | Khorram 1997 (analogue) |
| 2 weeks | IGF-1 rose; in older men, GH and IGF-1 were brought up to levels seen in young men | Blood sugar, blood pressure | Corpas 1992, Khorram 1997 |
| 6 weeks | More night-time GH; 2 of 6 strength tests and 1 endurance test improved in 11 older men | Weight, BMI, waist-to-hip ratio, DEXA muscle and fat; IGF-1 did not rise on a once-nightly schedule | Vittone 1997 |
| 16 weeks | Thicker skin in men and women; more lean mass, better insulin sensitivity, wellbeing and libido in men only | Body weight, fat mass, bone density, sleep quality; IGF-1 drifted back toward baseline by week 16 | Khorram 1997 (analogue) |
| 6 to 12 months (children) | Height velocity in GH-deficient children roughly doubled over the first 6 months | Not applicable to adults with normal GH | Thorner 1996 |
What the four sermorelin confessions say
None of them is a before-and-after. #685 is four months in and writes about liking the bedtime routine, not a measured result. #119 calls sermorelin their "sleep and HGH hit" inside a three-compound stack. #571 lists sermorelin among nine compounds over four months and says only CJC-1295 had a noticeable effect. #204 is a first-timer asking whether a cold injection should sting. Four stories cannot show a typical result; the honest finding is that nobody here reports a dramatic change. Read them on the sermorelin hub.
Why sermorelin before-and-after photos mislead
Photos rarely state what else changed: calories, training, sleep, a GLP-1 drug or testosterone. Lighting, pump, posture and water weight can shift a picture more than a modest rise in IGF-1. Clinics choose their best cases. In the trials above, the one group that showed more lean mass (older men at 16 weeks) still did not lose weight or fat. If a photo shows fast, large fat loss, sermorelin is unlikely to be the main reason. See sermorelin for weight loss and the general peptide before-and-after page.
Realistic expectations and what to track
Sermorelin needs a working pituitary, and its effect is capped by the body's own feedback, which is why it is milder than injected growth hormone (sermorelin vs HGH). The brand Geref was FDA-approved for children with GH deficiency and withdrawn in 2008; adult use today is off-label and usually compounded. A prescriber would normally judge it by IGF-1 blood tests over time rather than by photos, alongside blood sugar and other checks. WADA prohibits GH-releasing factors for tested athletes. Side effects are covered on sermorelin side effects.

Community Q&A
- How long does sermorelin take to show results?
- In studies, growth hormone rose within minutes of each injection and IGF-1 within about two weeks. Measured physical changes such as skin thickness or lean mass appeared, if at all, around 16 weeks and were modest. This is not a trial promise for any individual.
- Does sermorelin cause visible fat loss?
- Not in the controlled studies: weight and fat mass did not change at 6 or 16 weeks. Large before-and-after fat loss usually reflects diet, training or another drug.
- What do sermorelin users report after a few months?
- Our four anonymous reports describe a routine, a sleep claim inside a stack, and no noticeable effect. They are individual stories, not a result rate.
- Are sermorelin before and after photos reliable?
- Rarely. They are selected by whoever posts them and seldom say what else changed. Treat them as marketing, not evidence.
- Is sermorelin the same as HGH?
- No. Sermorelin prompts your own pituitary to release growth hormone; HGH (somatropin) is the hormone itself. See sermorelin vs HGH.
- Does Peptide Confessions give sermorelin dosing?
- Peptide Confessions does not publish dosing, timing, injection or sourcing guidance. Not medical advice.
