My Peptide Journey: Curiosity, Research and Adding More Tools to My Toolbox

If you have been following me for any length of time, you probably know that I am constantly researching, learning and trying to understand my own body a little better.

And lately, that research has taken me down a rabbit hole I honestly never expected to go down: peptides.

Here is a little bit about my peptide journey.

Before I go any further, I want to make something really clear. This is my personal experience and my personal research journey. I am not a doctor, and I am not telling anyone what they should or should not take. Some of the peptides I am researching are still being studied, and others have very specific approved medical uses that are different from the reasons people talk about them online. This is something I take seriously, and I believe anyone considering these types of treatments should have an honest conversation with a qualified healthcare professional.

For me, this started with Reta.

Retatrutide, often shortened to Reta, caught my attention because of the research surrounding its effects on metabolism, appetite and body weight. I had already spent a lot of time talking about my struggles with food noise, weight gain and trying to find my way back to feeling like myself again. I wasn't looking for a magic fix. I was looking for another tool.

That distinction is really important to me.

I have spent years talking about nutrition, movement, meal prepping, consistency and creating healthy habits. I know that there isn't a peptide, medication, supplement or anything else that can replace those things. There isn't a shortcut around taking care of yourself.

But I also don't believe we should be afraid of using every legitimate tool available to us when we need some extra help.

Once I started researching peptides, I realized just how massive this world actually is. There are peptides being researched for metabolism, tissue repair, inflammation, muscle, aging, cellular health and a whole list of other areas. And, of course, once I started researching, I wanted to understand more.

That's how GHK-Cu entered the picture.

What I found particularly interesting about GHK-Cu is that it isn't only something people are talking about in the world of injectable peptides. Copper peptides such as GHK-Cu are also used topically in skincare, which is probably where a lot of people have actually encountered them without even realizing it. You can find copper peptide serums from popular skincare brands, including The Ordinary, which has a Copper Peptides 1% serum. So if you've ever looked at the ingredients in your skincare products and wondered what all those complicated names were, there's a good chance peptides may already be part of that conversation.

GHK-Cu has been researched for things including skin and tissue repair, which is part of the reason it has become so popular in the skincare and longevity spaces. Who doesn't want to slow down the aging process? The difference between using a peptide topically in a skincare product and using an injectable form is obviously significant, though, and it's important not to assume that because something is available in a skincare serum, an injectable version has automatically been proven safe or effective for the same purpose.

The internet is full of people confidently telling you that something is the answer. Before-and-after pictures are everywhere. Someone has always found a new peptide, a new protocol, a new stack or a new "secret" that supposedly changes everything. But our bodies aren't Instagram posts.

What works for one person may not work for another. Something being popular doesn't automatically make it safe. And something being studied doesn't automatically mean we know everything we need to know about it.

So I have tried to approach this from a place of curiosity rather than blindly jumping from one thing to another.

I don't want this blog to become another place where someone reads about a peptide and thinks, "Great, I'm going to order that tomorrow."

That's not what this is about. This is about sharing what I am learning, honestly, I think there is something really empowering about becoming an educated participant in your own health.

For a long time, I felt like I was fighting my body.

I gained a significant amount of weight. I struggled with food noise. I fell out of love with the gym. I went through periods where my mental health made everything feel harder. And there were definitely moments where I wondered how I had gotten so far away from the person I used to be. But I'm starting to look at things differently. My health doesn't have to be an all-or-nothing project. I don't have to be perfect. I don't have to pretend that nutrition and exercise are always easy. And I don't have to pretend that additional medical tools don't exist just because I have spent years teaching people about healthy eating and fitness.

I can believe in nutrition and movement AND acknowledge that sometimes people need additional support. Those things can coexist.

For me, peptides are one small piece of a much bigger picture.

The bigger picture is still eating well. It's still getting enough protein. It's still moving my body. It's still going camping, hiking, travelling, walking Rosie and getting outside. It's still working on my mental health. It's still trying to sleep better, manage stress and actually enjoy my life.

The peptides don't replace any of that. And I don't want them to!

I'm learning about Reta. I'm learning about GHK-Cu. And I'm sure my research rabbit hole isn't going to end there. But I'm also learning about my own body.

I'm paying attention.

I'm asking questions.

I'm looking at the evidence.

And I'm trying to make informed decisions rather than emotional ones. There is also a very real safety side to this conversation. The market has blown up, there are so many people out there just looking to make money. Before you hop on Google and find a comany, do your research and read Redit threads about the company. There are a lot of fake products or fake websites out there. I have just recently had a bad vial of Reta. I ordered from a site that I have ordered from before but this vial is not real. I was scamed! The FDA has warned that unapproved and improperly compounded injectable products can carry risks related to quality, contamination, dosing and unknown safety profiles. It has also recently taken action against peptide sellers marketing products including retatrutide, as unapproved new drugs.

That's why I don't think the answer is simply "peptides are amazing" or "peptides are terrible."

The answer is: learn. Research. Ask questions. Talk to your healthcare provider. Understand exactly what you're putting into your body.

And remember that a tool is still just a tool. It doesn't do the work for you.

I'm still the one who has to make the food choices. I'm still the one who has to get off the couch. I'm still the one who has to go for the walk when I don't feel like it. I'm still the one who has to work on my mindset and decide that my health matters.

The difference is that I'm no longer interested in believing I have to do everything the hardest possible way.

I'm building my toolbox.

Nutrition is in there.

Exercise is in there.

Camping and getting outside are in there.

Mental health support is in there.

And right now, peptides are another thing I'm researching and learning about.

Maybe my toolbox will look completely different a year from now. Maybe some of these things will stay. Maybe some won't.

That's okay.

Because this isn't about finding one magic answer.

It's about finding what helps me build a healthier, happier life — and being willing to keep learning along the way.

I hope this has helpled anyone who is interested in doing their own research. Reach out if you have questions, I can do my best to answer them but I am NOT A DOCTOR, I am just conducting my own research.

Love, Liz 💕
