Peptide stacking is having a moment on TikTok right now, with creators talking up its promise of multi-targeted benefits, from fitness performance to skin goals. “In general, peptide stacking refers to combining two or more peptides in one treatment to achieve specific aesthetic and/or health goals,” says New York dermatologist Jody A. Levine, MD. That helps explain the rise of the Glow Peptide Blend, a provider-administered, injectable peptide stack that’s gaining traction on the platform.
Ahead, we’re breaking down what to know, with expert insight.

What Is the Glow Peptide Blend?
“The Glow Peptide is an injectable blend of peptides that work together with the goal to rejuvenate the skin, accelerate healing, reduce inflammation and stimulate collagen,” says Dr. Levine.
It’s a compounded blend that, as Miami dermatologist Dr. Deborah Longwill adds, is designed to support healthier, brighter, more resilient skin from within. She explains that the specific peptides in the formula work on a cellular level to improve how skin heals, hydrates and regenerates—resulting in a smoother, more even, lit-from-within glow. Because of those recovery-focused benefits, the blend is also commonly used to support recovery after cosmetic procedures such as lasers, microneedling and peels. For those reasons, it’s gained traction across both the beauty and fitness communities on TikTok.
How the Glow Peptide Blend Works
To understand the full benefits of the Glow Peptide Blend, it helps to look at its individual components. Dr. Levine explains that the formula combines three peptides: Body Protection Compound-157 (BPC-157), Thymosin Beta-4 (TB-500) and Copper Tripeptide-1 (GHK-CU)—each with its own role.
BPC-157 is a naturally occurring peptide known for its healing properties across multiple areas of the body, including the GI tract, muscles, nerves, tendons and ligaments. It’s also believed to promote blood-vessel formation and stimulate collagen production.
TB-500, according to Dr. Levine, is often used to support injury recovery and is commonly associated with sports therapy, where it’s used to improve mobility, flexibility and muscle formation.
Last but not least is GHK-CU, often referred to as copper peptide, which has gained popularity for its anti-aging benefits. “It works by binding to copper and delivering it to tissue, which in turn aims to soften fine lines, even out skin tone, reduce redness, speed up wound healing and bolster skin’s firmness and elasticity,” says Dr. Levine.
When Will You See Results With the Glow Peptide Blend?
Results vary, but doctors say most patients begin noticing improvements around four to six weeks. Dr. Longwill notes that peak collagen production and overall skin-quality changes tend to become more noticeable around the eight- to 12-week mark. Dr. Levine adds that taking a 15-day break between monthly cycles is ideal. Overall, consistency is key, as peptides work cumulatively over time.
How to Use the Glow Peptide Blend—Safely
While TikTok users are sharing their Glow Peptide Blend routines, doctors strongly advise against at-home injections. “Peptides should be handled with proper medical oversight to ensure correct dosing, sterile technique and safe administration,” says Dr. Longwill.
When administered through a provider, she explains, patients receive clear guidance on reconstituting the peptide, where and how to inject it and proper storage. It’s also important not to source peptides online. Although many TikTok users share websites and marketplaces selling the Glow Peptide Blend, ordering peptides from non-regulated sources isn’t considered safe. “That’s where you see contamination, incorrect dosing and poor manufacturing standards,” Dr. Longwill adds.
The takeaway: If you’re curious about peptide stacking treatments like the Glow Peptide Blend, start the conversation with a credentialed medical provider to see whether it’s appropriate for you.
