LL-37

41-year-old realtor here. I've been running LL-37 for about 6 weeks now, 5mg per day split into 2.5mg AM and 2.5mg PM. Main reason was recurring sinus junk and a couple of slow-healing cracks on my hands from dry weather and constant showings. Within maybe 10 days, sinus pressure dropped from most mornings to maybe twice a week. Hand cracks closed up in about 12 days vs the usual 3 weeks. I did get some redness at injection spots and one night of mild headache. If you're not seeing much, a higher dose might help, but that's not medical advice. I'm staying at 5mg for now.

41, trainer, so I'm around sweaty gyms and small cuts constantly. Ran LL-37 at 100 mcg subQ daily for 10 weeks. First 2 weeks nothing except mild redness at injection sites. By week 4, little knuckle scrapes and mat burns were healing in like 4-5 days instead of 8-10. I also didn't get the usual sinus gunk after coaching through a cold snap. Skin seemed a bit calmer, fewer random bumps. Hair? no real change. No flu-like issues, just occasional tiredness after pinning. Took a 2-week break and felt fine. Not magic, but solid support. Would use again.

I’m 45, a graphic designer, so lots of screen time and small scrapes from studio stuff. I started LL-37 at 200 mcg daily, subQ, and ran it for 10 weeks. Around week 3, a paper cut and a knuckle scrape healed in about 4 days instead of the usual 7. My skin looks less reactive, and I’ve had only one mild scratchy-throat episode in 10 weeks—normally I’d get two. First few injections left a red, itchy spot for maybe an hour; that faded after week 1. No major issues. Not dramatic, but I’ll likely cycle it again.

28-year-old woman here, husband is stay-at-home dad so I handle most lifting. Did 8 weeks LL-37 subQ, started 3mg daily, bumped to 5mg daily the last 2 weeks. Kept up rehab: dead hangs, resistance bands, 25lb dumbbells high reps. Right shoulder pain is gone, hand hasn't gone numb in weeks, left tennis elbow cleared up too. Only side effect was minor redness at injection sites. Now cycling off, hoping it sticks. Would rate 4/5. Rehab work matters, don't skip it.

I'm a 34-year-old grad student and I've been using LL-37 at 100 mcg subQ once daily, 8 weeks on and 3 weeks off. Around week 6 I plateau, so the break helps. I'm on my 5th cycle now. My skin keeps slowly improving: inflammatory spots went from about 15-20 to 4-5, and redness is down maybe 30%. It's not overnight, but it keeps building. Side effects are minor—some injection site redness/itching for a day and occasional mild headache. I plan to keep going.

I'm 36, desk job, had right shoulder impingement and left tennis elbow. Did 8 weeks LL-37 subq only. Started 3 mg once daily, bumped to 5 mg daily for last 2 weeks. Kept up rehab: dead hangs, bands, light 25 lb dumbbells high reps. Right shoulder pain basically gone, hand stopped going numb randomly. Left elbow pain gone too. Mild redness/stinging at injection spots, no other issues. Now cycling off and hoping it sticks. If you try it, add rehab work. 4 stars because expensive and not sure long term.

47-year-old realtor here. I've had chronic elbow tendinopathy for about a year. I ran LL-37 subcutaneously near the elbow twice daily at 0.25 mg per shot, so 0.5 mg daily, for 6 weeks. Pain went from 7/10 to maybe 5/10. No dramatic change, but I could grip files and drive stick a bit easier. Some injection-site redness and mild fatigue the first week. I'm planning 8 weeks on, 4 off, then another 8-week round. Maybe it helps with skin/wound stuff, but for tendon it's been underwhelming. I'll finish the protocol before judging fully.

I’ve logged 142 doses of LL-37, 5 mg each, pinning my thighs daily for about 4.5 months. Honestly? I haven’t felt a clear difference, and nobody has mentioned anything one way or another. The shot itself gives a bee-like sting, and both thighs now have a persistent bruise that never really fades. As a physical therapist I’m on my feet all day, so maybe that’s why. I’m not stopping yet—I’m 45 and not getting any younger. No infections, no dramatic recovery boost, just business as usual.

Started LL-37 about six weeks ago for stubborn folliculitis on my arms and some slow-healing scrapes from work. I do 2.5 mg in the morning and 2.5 mg at night, so 5 mg total per day. Around day 10 the redness dropped maybe 60%, and by week 4 I had zero new infected bumps versus 5-7 a week before. A couple of small cuts closed in 3 days instead of the usual 6-7. First few injections gave me a flushed face and mild headache for about 20 minutes, nothing since. I still think a higher amount might work faster, but I'm not a prescriber, so don't take this as medical advice.

52-year-old realtor here. I’ve been injecting LL-37 twice daily near my elbow for six weeks. Dose is 100 mcg each shot, so 200 mcg/day total. So far it’s been pretty underwhelming for chronic tendinopathy. Pain started around 7/10 and now maybe 5/10 on good days, but not the big change I hoped for. No infections or flu-like issues, just some mild redness and a little stinging at the pin sites. I’m planning to finish eight weeks, take four off, then try another eight. Anyone else run that schedule for tendon stuff?

38, grad student, running LL-37 for about 6 weeks now. I do 5mg daily, split into 2.5mg morning and 2.5mg evening, subQ. First 3 weeks: sinuses felt clearer, maybe 60% less congestion, and a lingering cut on my knuckle closed up quicker than usual. A couple of mild colds in my house didn't hit me as hard. Side effects: injection sites sting for 10-15 min, occasional redness, and one evening of flushing/fatigue. Sleep was fine. Higher dose might help, but I'm not a doctor, so don't take this as medical advice. For me it's worth it, though pricey.

34F, warehouse manager, running around on concrete all day. I used LL-37 subcutaneously at 100 mcg once daily for 6 weeks, then dropped to every other day. I'm not on any cycle. My cracked heels are basically gone—maybe 90% smoother. I had a few grey strands at my temples and now barely notice them. Skin looks more even and fresher. A box cutter slice on my thumb closed in about 3 days instead of the usual week. Mild stinging at the injection site for the first week, no other issues. Sleep unchanged. I'll keep it for skin and recovery.

Been on LL-37 for about 10 weeks, 100 mcg subQ each morning. I'm a chef, so my hands get nicked and burned constantly. Small cuts used to stay red and sore for 5-6 days. Now they calm down in 2-3. A forearm burn that usually takes two weeks to settle looked much better by day 8. First week I had mild injection-site redness and some tiredness, gone by day 10. Haven't caught the usual kitchen cold going around. Not overnight, but I notice it. Planning a break after 12 weeks.

I’m 28 and run a busy prep line, so my hands and heels take a beating. I did 100 mcg subQ daily for 6 weeks, no cycling. Around week 2 my cracked heels were basically smooth—zero splits by week 4. A knife nick on my thumb closed in 2 days instead of the usual 5. Skin tone looks more even and fresher. I only had a few greys, but they seem less noticeable now. Side effects: mild red bump at injection site for the first 5 days, one headache. No infections while working with raw fish, though I can’t speak to viral stuff. Not cheap, but I’d buy again.

I've been doing 5mg daily, split morning and night, for about 6 weeks. I'm a realtor, so I'm around clients, dusty showings, and crawlspaces constantly. I used to catch a sinus thing every 4-6 weeks. In this stretch I had one mild cold that cleared in 3 days instead of the usual 7-10. A paper cut on my knuckle looked way better by day 2. No real injection issues besides slight redness once. Sleep and energy are unchanged. I might try 7.5mg next month to see if it helps more, but that's just me. Value seems fair if you catch a sale.

I ran LL-37 at 100 mcg subq daily for 6 weeks. First two weeks nothing much. By week 4 my recurring cystic acne went from 2-3 spots a month to zero, and a stubborn scraped knuckle closed in about 5 days instead of 10. Sleep seemed a bit deeper too. Side effects: mild injection-site redness for 30 min and one day of loose stools. I’m 43 and work in a warehouse, so healing matters. I might bump to 200 mcg for a second 3-month run, but the constant sales pitch on that channel is annoying. Probably won’t keep following it.

28M accountant. Ran LL-37 at 100 mcg subQ daily, 5 on/2 off, for 6 weeks. Not doing any gear. First week: mild redness at pin sites and some afternoon fatigue; gone by week 2. My cracked heels went from painful fissures to maybe 80% smoother. A kitchen cut that usually takes 6 days closed in 3. Face looks less dull and more uniform. Only had a handful of silver strands before, now they're harder to spot. No major issues. Would use again.

Started LL-37 at 100 mcg subQ daily, five days on/two off, for about 9 weeks. I’m a 52-year-old PT, so I’m around small clinic cuts and gym germs constantly. Around week three, a recurring cracked knuckle stopped getting angry and healed in maybe four days instead of a week. Sinus stuff this spring felt milder and shorter. Injection site stung for 10-15 minutes and left a small red spot a few times, nothing major. Sleep and energy didn’t change much. I’m dropping to 100 mcg twice weekly for maintenance. Not a miracle, but I’d buy again.

I run LL-37 in 8-week cycles, then take 3 weeks off because I hit a plateau around week 7 or 8. Just finished my 5th cycle. Dose is 100 mcg subQ once daily, sometimes 200 mcg on weekdays if I remember. Skin is calmer, fewer flare-ups—maybe 60% fewer red patches on cheeks, and old acne spots are fading. No real side effects except a bit of injection-site redness for a day and occasional fatigue first week. Improvements keep building slowly. Not a miracle, but I’m sticking with it.

I'm 41, train clients 5 days a week, and kept getting little mat/equipment skin irritation and colds. Ran LL-37 at 200 mcg subq once daily for 6 weeks, then 3x/week for another month. Around week 2, small nicks and shaving cuts closed faster—maybe 2 days instead of 4. Had fewer sniffles despite gym exposure. No major issues, just a bit of red at injection sites first 5 days and one day of mild fatigue. Didn't notice viral magic or anything, but antimicrobial/immune side felt real. Cost is high, so 4. Would run again after a break.

I’m 36, desk job, and I’ve been running LL-37 at 100 mcg subQ once daily. I do 8 weeks on, 3 weeks off because I hit a plateau around week 8. Currently on my 5th cycle. Skin keeps improving slowly: maybe 30% less redness and fewer cystic spots around my jaw. Not a dramatic overnight fix. Side effects are mild—injection site stings and gets a little red for a day, plus a dull headache the first few days. No real issues otherwise. I’ll keep going as long as it keeps building.

45, work as a barber. Sliced my thumb with a trimmer, got red and puffy fast. Ran LL-37 at 200 mcg subQ once daily for 4 weeks. By day 10, swelling dropped maybe 80%, and the cut closed. Injection sites got itchy and red for the first week, plus mild fatigue. Thinking of bumping to 300 mcg for round two. Some doc online claims he ran it 3 months, but his constant sales pitch drives me nuts. Might mute his stuff. Not a miracle, but I'll likely try again.

I'm 36, an accountant, and I've taken 142 LL-37 doses at 5mg each. I haven't felt anything different, good or bad, and nobody around me has commented either way. The shot itself stings like a bee in my thigh, and both thighs now have a permanent bruise map. I'll keep going because I'm not getting younger, but I can't point to a result yet. Maybe it's subtle. Wish the injection site was kinder.

I’m 41 and work behind the chair all day, so my hands and face take a beating. I’ve run LL-37 in 8 weeks on, 3 weeks off because I hit a plateau around week 7 or 8. Just started my 5th cycle. I dose 100 mcg subq once daily, mornings. First two cycles were subtle. By cycle 4 my eczema patches on my hands were maybe 40% less angry, and a few old nicks healed faster. Side effects: some redness at injection sites and occasional mild headache first week. Nothing major. Improvements keep building slowly. Rating 4.

Used LL-37 at 100 mcg subQ once daily for 4 weeks. Injection site got red and slightly itchy for first 5 days, nothing wild. Around day 10 an old skin flare calmed by maybe 70%. Energy and sleep stayed about the same. Week 3 I tried 150 mcg for 5 days and felt achy with one mild headache, so I backed down. Now considering a second run at 200 mcg for 3 months, since Dr. Jones said he did that. But his constant sales pitch is annoying. I'm close to not recommending his channel anymore. Product seems decent, not magic.

34F, sales rep, on my feet all day. I used LL-37 at 100 mcg subQ daily for 6 weeks, then 3x/week for 2 more. I'm not cycling anything else. My heels went from cracked and sore to actually smooth—maybe 90% better, no more snagging socks. I had a few grey strands at my part; now I count maybe 6 instead of 15. Skin looks more even and less dull. A kitchen cut that usually takes 5 days closed in 2. Side effects: mild redness at injection site and a headache the first few days, nothing after. I'll keep using it.

I'm 50 and drive a truck, so my right shoulder and left elbow were a mess. Did 8 weeks of LL-37, subq only. Started 3mg daily, last two weeks went to 5mg. Kept up rehab too: dead hangs, bands, light dumbbells 25lb max, high reps. Right shoulder pain is gone, hand doesn't go numb randomly, left tennis elbow cleared up. Only side was some redness at pin sites and mild fatigue early on. Cycling off now, hope it sticks. If you try it, add rehab work.

Tbh I'm 52 and drive for a living, so sitting around with a chronic infection was miserable. I tried LL-37 after antibiotics did nothing. Not gonna lie, it seemed to clear it up. The antimicrobial thing is broad spectrum I guess, and it also messes with biofilms, which is why it worked on resistant bacteria imo. My wound healed faster too. Didn't really have side effects that I noticed. I'm not a doctor, just saying what happened to me.

I'm 52, work as a nurse, and tried LL-37 for a stubborn sinus infection. Not gonna lie, it fought it off in a few days. Imo the antimicrobial and antiviral defense seems broad spectrum. Tbh it's a pretty strong immune weapon. But watch dosing, because too much gave me inflammation. I backed off and it settled down. It's not a miracle cure or anything, but I was impressed.
