I work as a scientist based in the UK, focusing on cancer research, and peptides along with other bio molecules have long held my interest. My pharmaceutical industry experience includes impurity testing, dissolution testing, and content uniformity testing via HPLC.

Keeping weight off has been a particular struggle for me, which is why GLP-1s caught my attention. The idea of engineering or altering biological pathways to reach wanted outcomes (weight loss, tanning, prevention of more clinically relevant diseases) has always fascinated me, particularly through genetic engineering, even if that isn't really relevant here.

With so many posts right now, I'm feeling a bit overwhelmed, so any good thread recommendations would be greatly appreciated 👍

What brought y'all here?

Hi,

Thanks for telling us about your work. Because you brought up your background in cancer research and pharmaceutical testing, I'd like to hear your overall view.

I'm looking at peptides like GHK-Cu / Glow-type skin peptides, and maybe Retatrutide down the road.

My case is somewhat unusual: I've had two separate cancers — 1 was hormone-dependent, and the other was non-hormonal. I've been in remission for roughly 4 years.

I also live with an autoimmune condition and had Rituximab treatment not long ago.

Right now I'm on Mounjaro (tirzepatide), and I'm thinking about possibly switching to Retatrutide later on.

I'm not after medical advice or a protocol — just your broad scientific take:

In someone with a history like mine, would you say these kinds of peptides deserve extra caution?

Any general thoughts would be much appreciated.

Thank you.
 
Hey Berta, I appreciate you asking.

As far as I know, GHK-Cu drives angiogenesis (the making of blood vessels) along with cell migration. Those effects help with repair, yes, but they can help cancers too. In theory, that extra signalling from migration plus a bigger nutrient supply might wake a sleeping cancer cell, or push something neoplastic into becoming a cancer cell that proliferates actively. When it comes to hormonal cancers in particular, more cell migration could ramp up hormonal signalling, and that signalling was what started the cancer in the first place.

I'm not claiming that peptides which push cell signalling pathways and angiogenesis actually create cancers. My view is that they would give an advantage to cancers that are already present.

Because you're taking an immuno-modulatory drug, GHK-Cu gets even more complicated, since it may touch immune signalling and disrupt immune responses further.

Retatrutide, on the other hand, works through a completely different pathway, and lowering inflammation via fat loss would be genuinely helpful. Just so you know, inflammation is another factor that can come before cancer.

So the short version - GHK-Cu, yes, be extra careful. Retatrutide, in my opinion, would be fine.

Research pairing cancers with these peptides is pretty limited, so honestly these are just my theories, built on how I understand the biology.

I’m grateful for the thorough breakdown you provided — it genuinely means a lot.

Thanks to it, I now have a clearer picture of the possible dangers, particularly when it comes to GHK-Cu and how the immune system might respond.

I’ll proceed cautiously and give myself time to watch for any reactions my body shows.

Should something else come up down the line, may I reach out to you once more?

I appreciate you taking the time to share your view.

Hey there, wandering scientist!

Being here might end up feeling like a job for you, since sooner or later every one of us turns into an amateur chemist with a peptides specialty 🤣 And these days impurity testing (endotoxins) has become the trendy breakout topic in this space. So for you, this place could feel either like home or like work 😀

On the peptides-and-cancer front, have you ever done any work with PNC27?

Hello, I hope it’s okay for me to jump into this conversation 🙂

I don’t have a scientific background—what I know comes from my own personal experience.

PNC27 was new to me, so I did a quick search, and now I’d like to learn more about it.

If you’re willing, could you break it down in plain language?

For instance, what might the upsides and downsides be, and what’s the usual perspective on it within research?

Right now I’m in remission, so my interest here is mostly curiosity and wanting to understand the subject.

On top of that, I live with an autoimmune condition, which makes me want to approach this cautiously.

Thanks so much ahead of time 🙂
 
Given you're a scientist, I'd really like to hear your take on why more human research hasn't happened for peptides that can't be patented.
