Every peptide protocol at Pure Hydration starts with the same question: What do you want to improve? For some people, the answer is what they see in the mirror: skin that looks tired, fine lines that arrived early, hair that isn’t what it used to be. For others, it’s how they feel — the shoulder that never fully healed, the gut that acts up, the workout recovery that takes longer every year.
The answer shapes everything that follows. If your goals are skin, hair, and visible aging, GHK-Cu is the natural starting point. If your goals are recovery—joints, tendons, and gut health— then BPC-157 was built for that. And if you want both in a single protocol, Pure Glow Fusion combines GHK-Cu and BPC-157 with a third peptide, TB-500, in one blend.
This guide walks through all three, what each one does best, and how to know which belongs in your protocol. All Pure Hydration treatments are reviewed by a licensed provider before they’re compounded for you, ensuring you are getting the treatment that suits you best.

GHK-Cu: For Skin, Hair, and How You Age
GHK-Cu is a copper peptide, and it isn’t new to your body. You produce it naturally, and it plays a role in how your skin repairs and renews itself. The catch is that your levels decline significantly with age — which is part of why skin behaves differently at 45 than it did at 25.
Supplementing with GHK-Cu supports the building blocks your skin relies on, such as collagen and elastin. That’s why it’s known for improving texture, firmness, and overall radiance, and why it’s one of the most studied peptides for hair support. The changes it targets are the visible ones.
It’s also the peptide most people start with. The protocol is simple, the goals are easy to define, and the results are the kind you can see. If you’re new to peptide therapy and your priorities are aesthetic, GHK-Cu is the clearest first step.
BPC-157: For Recovery, Joints, and Gut Health
BPC-157 works on a different set of problems — the ones you feel rather than see. It’s a peptide modeled on a protective compound found naturally in the stomach, and it’s become one of the most talked-about options for supporting the body’s repair processes: tendons, ligaments, joints, and the gut lining itself.
That’s why it draws two very different groups of people. Athletes and active adults use it to support recovery from training and nagging injuries. Others turn to it for digestive comfort and gut support.
It’s worth being straightforward about the research: much of what we know about BPC-157 comes from early-stage studies. That’s exactly why it should never come from an unregulated source. At Pure Hydration, BPC-157 is prescribed by a licensed provider after a health screening and compounded through U.S. pharmacies that meet cGMP quality standards — so you know precisely what you’re taking, and someone qualified is monitoring how you respond.
Pure Glow Fusion: When You Want Both
Some goals don’t fit neatly into one category. You want your skin to look better and your body to recover faster. That’s the thinking behind Pure Glow Fusion, our most popular blend.
Glow combines three peptides in a single protocol: GHK-Cu for skin quality, BPC-157 for repair and recovery, and TB-500, which supports the body’s natural healing processes. Together, they cover more ground than any single peptide can — which is why Glow has become the go-to for people who want a complete protocol rather than a single-purpose one.
A typical Glow protocol runs for 6 or 12 weeks, with small morning injections Monday through Friday and weekends off. Your provider personalizes the plan around your goals, checks in during your cycle, and adjusts as needed.
GHK-Cu vs. Glow: What’s the Difference?
This is the question we hear most, and the answer is simpler than it looks. GHK-Cu is a single peptide with a single focus: skin, hair, and visible aging. Glow contains that same GHK-Cu — plus BPC-157 and TB-500 for recovery and repair.
So the real question is about your goals. If they’re purely aesthetic, GHK-Cu on its own is the simpler, more focused choice. If you’re also training hard, managing an old injury, dealing with gut issues, or recovering from aesthetic treatments, Glow gives you the skin benefits and the recovery support in one protocol. You’re not choosing between a good option and a better one. You’re choosing between one goal and two.
How to Know Which Peptide You Need
You don’t have to figure this out on your own — and honestly, you shouldn’t. The right peptide depends on your goals, your health history, and factors a quick article can’t assess.
Here’s how it works at Pure Hydration. Start with our free peptide quiz — two minutes of questions about your goals and health. From there, you’ll connect with a licensed provider who reviews your answers, completes a health screening, and builds a protocol specifically for you. Every prescription is compounded fresh through ISO/NSF cGMP-certified U.S. pharmacies.

Frequently Asked Questions
Do you need a prescription for peptides like GHK-Cu and BPC-157? Through Pure Hydration, yes. Every protocol is reviewed and prescribed by a licensed provider after a health screening, then compounded through certified U.S. pharmacies. It’s the difference between physician-guided therapy and buying an unverified product online.
Is GHK-Cu safe? GHK-Cu is a compound your body already produces, and it’s generally well tolerated. The most common side effects are mild and temporary, like slight irritation at the injection site. Your provider monitors your response throughout your protocol.
When is the best time to take the Glow peptide? Most Glow protocols use weekday morning injections, around the same time each day, with weekends off. Consistency matters more than the exact hour — your provider will set the schedule that fits your protocol.
Can you take GHK-Cu and BPC-157 together? Yes — that combination is the foundation of Pure Glow Fusion, which pairs both with TB-500 in a single prescribed blend. Your provider can also build a custom protocol if a standard blend isn’t the right fit.
Is injectable GHK-Cu better than topical? They work differently. Topical GHK-Cu acts on the skin’s surface where it’s applied, while injections deliver the peptide systemically. We break down the full comparison in our topical vs. injectable guide.
Start With the Right Question
The best peptide isn’t the most popular one. It’s the one matched to what you’re actually trying to improve — chosen with a provider who knows your health history and stays with you through the protocol.
