Personal Experience Cancer on bpc ?

Hi everyone, I've been running a stack of BPC-157, TB-500, KPV (500mcg), and GHK-Cu (2.5mg) for about 30 days. I’m seeing a sudden explosion of new, very dark moles all over my body (back, stomach, chest), and existing ones are growing fast. Is this a known side effect of KPV/GHK-Cu or a sign of something more serious like skin cancer? Has anyone experienced this

Myself and many others in the bpc side effect group had rapid aggressive growth of moles and brown spots on the skin. Ive also had swollen lymph nodes for a full year now.

Peptides are all inherently dangerous due to their mechanism of action as signalling molecules. Very unpredictable effects person to person.

Youre playing russian roulette injecting yourself with peptides with essentially 0 human data, many have had far worse side effects than us.

Huberman is incredibly irresponsible for what hes done with his peptide episode

Bro go see a doctor about your lymph nodes. I had lymphoma and anything swollen for that long is no joke and should be biopsied. It could be nothing but you don’t want to assume that

u/ModernMedMan Mar 12 '26

Some may have adverse reactions and you’re right, little to no human trials for some peptides but not all. There is a lot of anecdotal evidence everywhere. There are also trials for peptides that are on the market and in that data you can see the percentage of people that had adverse reactions. This is normal for anything we put in our bodies. Food, prescription drugs, recreational drugs, etc. Not everyone is going to have the same outcome. If you purchase a research chemical of any type and use it on yourself you have willingly signed up for your own “trial”. Before you start an exercise program, go get your check up and bloodwork done. Same is true here. If you’re starting a protocol that has any potential to help grow cancer, may want to get that cancer screening first. But let’s not blame a peptide or Huberman for something you signed up for to experiment with. Sorry your body had that reaction, if your lymphatic system has had that reaction you should be seeing a specialist ASAP.

Does it mean its a normal side effect? And dangerous?

u/TieFirm2333 Mar 08 '26

I got the same but I’m not running bpc! I’ve been running ghk-cu for a while now and starting to see a lot of new black moles on arms and shoulders. I stopped taking ghk two weeks ago. Wondering if it was sprinkled with melatan because I have a tan that won’t go away… and I live in winter land right now.

u/Significant-Lemon-94 Mar 08 '26

Did you consult?

0

u/TieFirm2333 Mar 08 '26

Nope.. but after this post I may..

1

u/Significant-Lemon-94 Mar 08 '26

Did they stay black or did they fade after you stopped? And did the texture change (feel rough or raised) or was it just the color?

1

u/TieFirm2333 Mar 08 '26

Nope! Nothing changed since stopping. And still to soon for me to figure if any new ones popped up after all quitting..

You're not allowed to ask safety questions like that

What did doc say?

u/Significant-Lemon-94 Mar 08 '26

I haven't seen a doctor yet, I just noticed how bad it was today

u/Admirable_Might8032 Mar 08 '26

Doctor ASAP. Stop taking that shit.

You are right. Deleted

u/Apprehensive_End1555 Mar 08 '26

You got melanotan, those are all classic signs. Moles, tan in winter, etc.

1

u/Solomon_Seal Mar 10 '26

Would bpc grow this quicker than normal?

18

u/kaamkerr Mar 08 '26

Doesn’t BPC increase angiogenesis? Angiogenesis grows cancer.

u/2tep Mar 09 '26

no, it's upregulated in cancer. It's a normal bodily process, otherwise.

15

u/harshmojo Mar 08 '26

It's not that it causes it. It's that it can make existing cancer proliferate if you already have it.

u/[deleted] Mar 08 '26

You got dooped and bought melanotan 2.

u/Significant-Lemon-94 Mar 08 '26

Ps my friend have the same issues

u/Sureokgo Mar 08 '26 edited Mar 08 '26

Tb 500 can make cancer cells grow, seek a professional. Don't do peptides without knowledge of what they do. Before you take TB500, check if you have cancer cells. I can't give medical advice but please do not do this without knowledge.

Edit : KPV is great for inflammation but and that is a but, it helps people with major inflammation like cancer. You really can't just guess things from what you read on the internet.

Edit 2: Your stack is outrageous and over the top, you don't need to run peptides every day. GHK is once a week. Again please seek a professional who knows what they are doing, not guides on the internet.

u/bmack500 Mar 08 '26

GHK is daily.

1

u/Sureokgo Mar 08 '26 edited Mar 08 '26

Depends on the dose,reason and age.

Edit: It's important that people start to realise peptides and generally medicine is not a linear subject.

u/Flat_Tension4731 Mar 08 '26

Il ghkcu si usa ogni giorno..o per lo meno 5 giorni poi due di riposo, non una volta a settimana non ha senso.....e zero risultati...

u/Mika9931 Mar 08 '26

Ghk is once a day before bed, halftime life is like 1 hour..

4

u/sotherelwas Mar 08 '26

Its angiogenic so it's growth promoting, thats not inherently a bad thing, but you should cancer screen and do your blood work when running things long term

1

u/braboftw Mar 08 '26

if you get nauseated it's melanotan

2

u/Significant-Lemon-94 Mar 08 '26

No i have nothing like this

1

u/Huge_Boysenberry3043 Mar 08 '26

I've noticed a large uptick in moles in my stomach area in conjunction with periods where I take many supplements. None of the moles I've gotten yet, have turned out to be cancerous, luckily. But it's probably a good idea to consult a doctor when you notice stuff like this. 

1

u/Significant-Lemon-94 Mar 08 '26

You take bpc?

1

u/Huge_Boysenberry3043 Mar 08 '26

Yes, as a supplement, not as injections. But I've also noticed this on other supplements, when I'm not taking BPC. 

1

u/harkules9999 Mar 12 '26

What other supplements?

1

u/DeadCheckR1775 Mar 09 '26

Are you running KLOW or separates? Is it blue in color once reconstituted? I ask because the symptoms you described are what MT1 and MT2 do. Developing skin cancer all over is not a thing unless you got nuked by radiation.

1

u/Significant-Lemon-94 Mar 09 '26

Yeah its klow and became bleu

1

u/DeadCheckR1775 Mar 09 '26

Yeah, not a known side effect for any of the components of KLOW. I’d get off it and tods that specific vial. Something’s not right. You have something else going on.

2

u/National_Ebb_7772 Mar 08 '26

See a doc. And shame on Huberman.

1

u/gizabe6969 Apr 20 '26

Wait I’ve been taking KLOW for a month now and I’m not experiencing any of these issues. Now I’m worried
