I started taking sermorelin about three weeks ago as a way to recover a little faster and sleep better because, let's face it, I'm not 22 anymore. Personally, I've noticed a massive difference in sleep, mood, energy levels, and performance in the gym.
for the last couple of years (maybe 2) I’ve just felt like I’m dragging. I would sleep all of the time and it was never enough. The gym basically became nonexistent and I was a 5x/week gym goer. Ever since starting this, I just feel like my old (younger) self.
This was my first time trying Sermorelin. After injecting 500mcg, within minutes both of my hands started itching. Then I felt my lips and face swell up. My heart started to beat out of my chest and I started to sweat profusely.

Users report
A loyal minority rate it the budget GH option: they 'slept like a log', report better recovery, smoother skin and more energy, and see IGF-1 rise to the upper-normal range on bloodwork. Many call it weaker than CJC/Ipa or tesamorelin, and roughly a quarter notice nothing, often while starting TRT or a GLP-1 at the same time, which gets the credit. Vivid dreams, night sweats, water retention and acne recur. The most serious pattern is sensitisation: a dozen-plus first-hand accounts of hives, face and lip swelling, vomiting and collapse, sometimes needing the ER. These usually come on the second course or after earlier CJC/ipamorelin or tesamorelin use, but occasionally on the first dose.
Best effects
Sleep quality · recovery · IGF-1 into upper-normal range
Downsides
Weaker than alternatives · flushing · injection-site reactions
Approved drug — previously approved in US (Geref, pediatric GH deficiency; discontinued 2008)
Typical use
200-500 mcg nightly subQ, 5-7 nights/week.
Getting it
Geref was withdrawn in 2008 for commercial reasons; US telehealth and TRT clinics now prescribe compounded injections, troches and nasal sprays. Also sold by research-peptide vendors.
Stacked with
TRT: The most common context; clinics sell it as an add-on to testosterone, and several users credit the testosterone rather than the sermorelin for their results. · Tirzepatide or retatrutide: Taken to hold on to muscle during GLP-1 weight loss; most visible fat-loss results in these threads come from the GLP-1. · Ipamorelin: A cheaper alternative to CJC-1295/ipamorelin; one user's improved sleep turned into 3 am waking and a pounding heartbeat once ipamorelin was added.

I’m 35 (F) naturally strong but went to superhuman with Sermorilin and could always do like 70-90 lbs on adductor/abductor and they went to 145 lbs after 20 years of solid lifting with little more gains. Superhuman strength and sleep.
I also have been mostly bed bound for the past 3+ years from CFS & POTS. I have major post exertional malaise. I’ve been taking the sermorelin for almost a month now. & I’m getting out of bed again. It has been a small miracle l.
I’ve been on it for about a month. It was also recommended by my doctor. I’ve had better sleep and more muscle definition. Definitely less store after a hard workout.
I’ve been taking it for two months and have noticed significantly better gym recovery and skin feels much smoother. I’m 49m and also using 220mg testosterone weekly, and 6mg Reta weekly for reference.

The question of effectiveness for me comes down to IGF 1 test, which came in at 258 ng/ml (healthy range is 41-279), putting me at upper range while staying safe.

I got a mild rash on my cheeks after 200mcg. I got mine through a telehealth company with a prescription. We agreed I’d stop and wait awhile. if I’d like to start again I would start lower. I restarted and it’s been great for my sleep and vitality.

I started Sermorelin 0.20 ml about a week ago and the dreams are INTENSE. Like weird subconscious shit from high school intense. The sleep’s great, but good lord the dreams are heddy.
I’ve noticed none of the Sermorelin benefits. My sleep hasn’t improved, my skin hasn’t changed at all, still have bloating and really didn’t shed any fat.

The weight isn't muscle, its water. I don't look leaner by any stretch. I am moving away from it. I assume it just isn't for everyone. It also didn't really help with my sleep.
I’m on it and only at 100mcgs because of the water retention. Also it gives me a headache at higher dose. Another thing I get is a stuffy nose when I wake and then it runs the rest of the day.

A few months later I went back to Sermorelin and pinned just once and all my old pins flared up, body got hot and my eyes started to swell. Took an antihistamine and it did calm down after about a half hour, very close to going to hospital.

On the 3 dose of this round, I immediately got flushed, itchy, nauseated, beating cheat, and a feeling of impending doom. I went to vomit and woke up on the floor in my wife lap with medics trying to wake me up.

I had a bad reaction to the semorelin oral trounces that dissolve under the tongue. They caused ulcers in my esophagas. I thought I was having heart attacks or pancreatic failure. I got my digestive track scoped, and they found black burns in my esophogas.

Each bead is one amino acid in the peptide's chain, coloured by its side chain: grey for non-polar, cyan for polar, blue for positively charged and fuchsia for negatively charged. Length and mix tell related peptides apart at a glance, from a two-residue dipeptide like carnosine to a 43-residue protein like thymosin beta-4. The colours describe chemistry only and predict neither effect nor safety.

Report grades
Every first-hand Reddit or X report is graded on its own, from glowing through positive, mixed, nothing and negative to bad reaction, and the bar shows how those grades split. Posts that look vendor-adjacent stay on the peptide's page but are left out of the counts.
GlowingPositiveMixedNothingNegativeBad reaction
% positive
The share of a peptide's graded Reddit and X reports that are glowing or positive, vendor-adjacent posts left out. A peptide with few reports is pulled toward the average of all reports, as if it had eight average ones besides its own, so two glowing posts cannot top the list. Kept peptides rank by the same reports' mean grade, shrunk the same way, and excluded ones follow in that order.
Researcher estimate
No first-hand report of this peptide has been graded yet, so the figure is the researchers' own rating out of 10 from what they read about it. It ranks alongside the computed scores until reports arrive.
Safety tier
Each peptide is tiered clean, caution or excluded from its five risk axes under the chosen safety bar. An excluded peptide has a plausible route to serious harm, so it stays listed with the reason but ranks behind every other entry, however good its reviews.
Safety bar
The safety bar sets how much risk it takes to exclude a peptide. Strict: out on any serious mechanism with little human data, or any documented serious harm. Balanced: out on documented serious harm (unless it is obvious, reversible and from a regulated product), or a serious mechanism whose harm would be silent with no human data at all. Evidence only: out only on documented serious harm in humans that is lasting, delayed or from grey-market product.
Seen harm
Documented serious adverse events in humans, from 0 for none despite real exposure to 3 for deaths or several well-documented serious harms. Serious means a hospital or emergency visit or harm lasting weeks, so a headache or a bad night does not count.
Mechanism
A plausible biological route to serious harm at the doses people use, such as growth-factor signalling, hormone-axis suppression, heart or blood-pressure effects or immune activation. It runs from 0 when none is known to 3 when a dangerous pathway has been shown in living animals.
Data gap
How little human safety data exists for the molecule actually sold, from 0 for an approved drug with large trials and years of use to 3 for no human safety data at all. A modified analogue does not inherit its parent's trials.
Silent harm
Whether the feared harm would show quickly or stay hidden, from 0 when it is obvious and goes on stopping to 3 when it is silent and delayed, like tumour promotion or slow organ damage. User reports cannot reveal a harm that takes years to appear, so a high score here limits what good reviews can tell you.
Product
The risk of what people actually buy, from 0 for a regulated pharmacy or supplement product taken by mouth or on the skin to 3 for a grey-market injectable. In one dataset of 6,441 grey-market samples, 42–71% failed basic quality criteria and 15% carried endotoxin.
Evidence
The strongest kind of study behind the peptide's effects, from an approved drug through human controlled trials and small human studies to animal work or nothing of its own. Animal results often fail to carry over to people.
Access
How people get it: as an approved drug, a compounded prescription, an over-the-counter supplement or from the grey market, where nobody checks the vial. The channel decides both the legal position and the risk of a bad batch.
Price per month
Thirty days of the typical dose, from its low end to its high end, priced at the listing a careful buyer would choose: in stock, from a shop scoring 4 of 5 on trust (third-party tested where no score is set), failing that 3, a pure pack before a blend, a European shop first, then the cheapest per mg. The range is the dose's, not the shops'. A per-dose amount counts once a day unless the dose says otherwise. Prices are in euros at ECB rates of 2026-10-29, before shipping; the shop table keeps each listing's price per mg, per gram for bulk supplements. Where no listing can be priced the researchers' own estimate stands in, and says so.
Dose users report
The middle half of the daily doses stated in at least five first-hand reports, vendor posts left out. Where its middle sits more than twice above or below the declared dose, the month is priced at it as well, since what people take is what they pay for.
Testing
Whether the shop publishes lab results: third-party tested means an independent lab checks each batch, own COA means the shop's own certificate of analysis, and no public tests means neither. A certificate shows purity, not safety.
Added peptide
Some packs sold under one peptide's name hold a second one, such as 5 mg GHK-Cu in a nasal kit, stated only in the description. Sprayed in the nose or injected it reaches the blood like an injection, so it carries the risk of that route and is tiered as the injectable form, whatever its tier on the skin. A pack whose page gives no contents list may hold more than its name.
