Used both, didn’t do anything for me
Anonymous user, r/BiohackingUser reportReply in a thread about topical GHK-Cu and AHK-Cu for hair loss; the user reported no benefit from either. It either seems to work amazingly or not at all.
Anonymous user, r/fitness40plusUser reportComment in a thread collecting personal tendonitis experiences with BPC-157. Used it for 2 months I didn’t see any difference
Anonymous user, r/Peptides_for_WomenUser reportA different user in the same thread reporting no benefit. Anecdotal. Dreams were crazy! But definitely improved my REM.
Anonymous user, r/BiohackingUser reportOne user's self-report in a Reddit thread on sleep; not verified. It wasn't until VIP that I felt like I'm starting to live.
Anonymous user, r/CIRSUser reportSelf-report from someone with chronic inflammatory response syndrome (CIRS), POTS and chronic fatigue using nasal VIP under a practitioner; uncontrolled anecdote, and brain fog temporarily worsened. My eyes feel more wide open and brain feels like it's working.
Anonymous user, r/NicotinamideRibosideUser reportSingle forum self-report shortly after starting; uncontrolled and possibly placebo. I take Lipo-C with my tirz and it’s been a game changer for me.
Anonymous user, r/tirzepatidecompoundUser reportEnergy report from a user also taking tirzepatide who was unsure how much came from tirzepatide versus the pharmacy-branded lipotropic blend; others in the thread noticed nothing. Sleeps been phenomenal, and my belly fat is being assassinated.
Anonymous user, r/BodyHackGuideUser reportForum reply from a user of a tesamorelin and ipamorelin blend; others in the thread report water retention and carpal tunnel symptoms. Yes oh my god I feel exhausted after my injections. My body aches
Anonymous user, r/B12_DeficiencyUser reportReply in a thread where several people with diagnosed deficiency describe fatigue and aches after injections. For me it has been the first peptide to absolutely smoke my hunger.
Anonymous user, r/BiohackingUser reportUser report in a cagrilintide experience thread; the user was also taking retatrutide. I haven't been sick or had a herpes outbreak since using it either.
Anonymous user, r/BiohackersUser reportForum post claiming improved immune biomarkers after a course of thymalin; no independent verification. Tried both in the nose. Felt nothing. Total waste of time and money.
Anonymous user, r/BiohackingUser reportForum reply about intranasal Semax and Selank; other replies describe subtle benefits or mild drowsiness. HGH for 4 months and best sleep and recovery I have ever experienced.
Anonymous user, r/BodyHackGuideUser reportSingle forum self-report; other users in the same thread reported worse sleep, feeling feverish, or no effect, and product authenticity was unverified. The days I don’t take it, I can’t sleep, days I do, I sleep like a rock.
Anonymous user, r/BodyHackGuideUser reportUser taking CJC-1295 without DAC combined with ipamorelin, describing sleep on and off days. The area that bruised has formed a small, hard pea sized lump under the skin.
Anonymous user, r/cosmeticsurgeryUser reportPost six days after injections under the chin; single self-report. I felt like I was taking information in a lot more smoothly and effortlessly.
Anonymous user, r/BiohackersUser reportSingle self-report from a forum user describing the first week of nasal use; the same user reported more headaches and trouble falling asleep. Lr3 is a serious gym pump after about 2 weeks but those gains aren't permanent.
Anonymous user, r/PeptideGuideUser reportSelf-report from a long-term user in a forum thread; uncontrolled anecdote. I actually walk barefoot on the carpet, and it no longer feels like razor blades.
Anonymous user, r/neuropathyUser reportForum report from a user with neuropathy; the same user earlier described painful nerve flares in the feet and paused use. I started LipoB and Vitamin B12 injections about a month ago and feel 100% better.
Anonymous user, r/ZepboundUser reportUser also taking a GLP-1 medicine and going through menopause, describing energy rather than weight change. Injectable routes of administration may present a particular risk for immunogenicity.
US Food and Drug AdministrationRegulatorFDA staff assessment of compounded injectable thymosin alpha-1, citing possible aggregation and peptide-related impurities. I would say that SS-31 is the closest I've come to what feels like the movie Limitless.
Anonymous user, r/cfsUser reportUnverified self-report; in the same thread several people with ME/CFS described crashes, fatigue and palpitations. EGRIFTA WR is not indicated for weight loss management as it has a weight neutral effect.
US FDA prescribing information (Egrifta WR)RegulatorLimitations of use in the FDA-approved label, revised March 2025. Improvements in all prespecified cardiometabolic measures were observed with tirzepatide.
Jastreboff AM, et al.ResearchersSURMOUNT-1, a 72-week phase 3 placebo-controlled trial in 2539 adults with obesity (N Engl J Med, 2022). I had a dull headache for the first 3 days and felt a little sluggish for the first 5 days.
Anonymous user, r/BiohackingUser reportOne user's self-report; the same user also noted weight loss and more frequent urination. Anecdotal. HCG and TRT go together like peanut butter and jelly! HCG makes up for what TRT takes away.
Anonymous user, r/TestosteroneUser reportForum self-report; the same user noted carrying more water from higher estradiol, and others in the thread reported mood swings or poor sleep. AOD9604 displayed a very good safety and tolerability profile indistinguishable from placebo.
Stier H, Vos E, Kenley DResearchersSummary of six randomized placebo-controlled trials; two authors were affiliated with the developer, Metabolic Pharmaceuticals. Thus the hypothesis regarding DSIP as a sleep factor is extremely poorly documented and still weak.
Kovalzon VM, Strekalova TVResearchersMini-review abstract; no DSIP gene, precursor protein or receptor had been identified. My RHR went up by 10 for the first 2 months on reta and now has been in a steady decline the past 2 months.
Anonymous user, r/RetatrutideUser reportUnverified self-report on resting heart rate; others in the thread stopped because of persistent heart-rate rises. FDA lacks important information regarding any safety issues raised by selank acetate administered to humans.
US Food and Drug AdministrationRegulatorFDA safety summary for selank acetate (TP-7), listed among compounding nominations that were later withdrawn. There were no significant differences between ipamorelin and placebo in the key and secondary efficacy analyses.
Beck DE, Sweeney WB, McCarter MDResearchersConclusion of a phase 2, double-blind, placebo-controlled trial in 114 adults after bowel surgery; the drug was well tolerated but did not speed recovery of gut function. I can focus longer and mental stamina feels better, but I also feel a bit spacey/detached and slightly antisocial.
Anonymous user, r/NootropicsUser reportForum post from a user of Russian intranasal Semax describing mixed effects. He told the doctors writing up his case that if he’d known this could happen, he never would have touched the drug.
Julia Nevski, McGill Office for Science and SocietyPressDescribing a published case of a 41-year-old man who developed a 22-hour priapism after buying melanotan over the counter. There's no way to know what the substance actually is, was or will be tomorrow because that name has no legal meaning
Russell Wesdyk, associate director, FDA drug centerRegulatorSaid at FDA's July 2026 compounding advisory meeting about substances such as TB-500 that are not recognized pharmaceutical ingredients in the U.S. These data suggest that kisspeptin has potential as the first pharmacological treatment for men with low sexual desire.
Mills EG, et al.ResearchersCrossover placebo-controlled trial of intravenous kisspeptin-54 in 32 men with hypoactive sexual desire disorder (JAMA Netw Open, 2023). For effectiveness, we know that 30% of patients on placebo will have a self-reported response or even objective response
Dr. Brian Lee, Keck School of Medicine of USCClinicianFDA advisory committee member explaining his no vote at the July 2026 FDA peptide compounding meeting. FDA has not identified any human exposure data on drug products containing KPV administered via any route of administration.
US Food and Drug AdministrationRegulatorFDA safety-risk summary for KPV, listed under nominated-but-withdrawn substances on its compounding safety-risks page (content current as of April 2026). A search of the published literature returns no trial, paper, or patent covering these four compounds together at this ratio.
Kevin Nathan, Plastic Surgery KeyPressEvidence review of the KLOW blend on a site that also points readers toward research-peptide suppliers. I'm 37 and lost about 53 lbs on Wegovy. I'm really happy with the weight loss, but my face changed much more than I expected.
Anonymous user, r/SemaglutideUser reportSingle forum self-report; the user later attributed the change to rapid weight loss rather than the medicine itself. FDA has not identified any human exposure data on drug products containing MOTs-C administered via any route of administration.
US Food and Drug AdministrationRegulatorFDA safety assessment written during its review of a nomination to use MOTS-c in pharmacy compounding. Once this stuff builds up in your system, it really does give you a good clean boost of daily energy without affecting your sleep.
Anonymous user, r/BodyHackGuideUser reportSelf-report from a user also taking the investigational drug retatrutide and other compounds; other commenters in the thread noticed no effect. It’s pretty nice for tightening the skin temporarily and making it hard for me to raise my brows. I like it for when I am going out.
Anonymous user, r/45PlusSkincareUser reportUnverified self-report on a skincare product containing Snap-8; other users in the thread saw no improvement. FDA has identified serious adverse events associated with CJC-1295 including increased heart rate and systemic vasodilatory reaction.
U.S. Food and Drug AdministrationRegulatorFDA's safety assessment of CJC-1295 as a nominated compounding substance; the nomination was later withdrawn. Interesting. I find it damages my sleep. It pushes me too far into deep sleep, and the lack of REM means I wake up groggy and sluggish.
Anonymous user, r/BodyHackGuideUser reportA different user in the same thread reporting the opposite sleep effect; anecdotal. I’m not sold on it. Have used it about 10 times. Maybe 2 or 3 times it helped a little. Once it worked well and the rest virtually no impact.
Anonymous user, r/erectiledysfunctionUser reportForum reply from a man using it off-label for erections; the original poster in the same thread reported a strong effect plus significant nausea. Seizures have been reported to occur in patients with or without preexisting seizure activity receiving either oral or intravenous levocarnitine.
CARNITOR prescribing information (FDA-approved label)ManufacturerAdverse-reaction section of the US prescribing information for levocarnitine. Compounded injectable drugs containing GHK-Cu may pose risk for immunogenicity due to the potential for aggregation and peptide-related impurities.
US Food and Drug AdministrationRegulatorFDA safety summary for injectable GHK-Cu; FDA adds that there are limited human data to inform safety. And yes, the glowy skin will fade once you stop using it. Not immediately obviously but after a few weeks, the skin will fade back to its original color
Anonymous user, r/30PlusSkinCareUser reportOne user's self-report about IV glutathione for skin lightening; anecdotal.
Questions about this site
What is humanpeptides.fyi?
An adult educational index of what has been studied, published and reported about 48 peptides and related compounds, searchable by name, brand, street name or goal.
Does humanpeptides.fyi make any health claims?
No. It makes no claims of its own. Every benefit, side effect, nickname and quote is attributed to and linked to the source that published or posted it.
Does the site sell peptides?
No. The site sells nothing and has no checkout, accounts or prices. Seller pages are cited only where a claim or a name first appeared, and are labelled as sellers.
How is the strength of evidence shown?
Every entry carries one of five labels: Approved (specific use), Trial-backed, Early human, Preclinical or Unstudied, so a mouse study never reads like an approved drug.
Is anything here medical advice?
No. Nothing on the site is medical advice or dosing guidance. Talk to a licensed clinician before making any health decision; in an emergency call 911.
How much is actually known.
