Pre-menopausal, unable to lose weight despite strict diet and daily exercise. Exhausted, frustrated, and had tried 4 other supplements.
I had given up. Genuinely. I was eating 1,400 calories a day, working out five times a week, and gaining weight anyway. My doctor told me it was just "part of getting older." Within three weeks of starting Retatrutide, my hunger completely changed. Not suppressed — just normal. Like it was in my 30s. By week 16 I was down 34 pounds and my last DEXA scan showed I hadn't lost a single pound of muscle. I tell every woman I know about this.

“People stopped me at my daughter's wedding to ask if I'd had work done. I haven't. After 10 weeks of GHK-Cu my skin is genuinely different — it's dense and firm in a way I haven't felt since I was in my 30s. The lines on my forehead are still there but they're soft. My face looks like it belongs to me again.”

“Three years of CrossFit, meal prepping, tracking macros — and my weight didn't move. Eight weeks after starting Retatrutide it moved 19 pounds. I finally understand what was happening: my hormones had changed the rules and no one told me. This peptide changed the game.”

“I started noticing my skin looked deflated — like the volume was just gone. After 8 weeks of GHK-Cu I look genuinely rested and firm. The scarring I've had for 15 years has faded visibly. I use both the injectable and the cream and together they work like nothing I've ever tried.”

Everything researchers need to know about our compounds, storage, and protocols.
GHK-Cu (Glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide found in human plasma that declines significantly after age 20. The striking blue color comes from the copper(II) ion bonded to the peptide chain — this is completely normal and actually confirms the product is active and properly complexed. A colorless GHK-Cu solution would suggest the copper is absent or has dissociated.
Both contain the identical active compound — the difference is purely quantity. The 50mg vial is ideal for new users starting a protocol, while the 100mg offers better value per mg for experienced users on ongoing protocols. At $89.99 for 100mg vs $69.99 for 50mg, the 100mg vial saves you roughly 36% per mg. Both reconstitute to the same concentration per mL.
Yes — GHK-Cu is one of the few peptides effective via multiple routes. For topical use, reconstitute with more bacteriostatic water (10mL for 100mg gives a 1% solution) and apply to clean skin 1–2x daily. For subcutaneous use, a more concentrated solution (5mL per 50mg = 10mg/mL) is typical. Combining both routes — injectable for systemic collagen stimulation and topical for surface skin renewal — delivers the most comprehensive results.
Most research protocols observe measurable changes in skin density and texture within 4–8 weeks of consistent use. Collagen synthesis is a gradual process — the peptide signals the body to produce more structural proteins, which takes time to accumulate and become visible. Subjects using both injectable and topical GHK-Cu concurrently tend to report earlier observable changes than those using a single route.

FeaturedWeight LossWhile other weight loss peptides work on one receptor at a time, Retatrutide hits three simultaneously — and the results women are seeing are unlike anything in the history of metabolic wellness.
After 40, women's bodies play by completely different metabolic rules. Here's why conventional approaches fail — and how Retatrutide's tri-receptor mechanism gives women their power back.
It's bright blue. It's naturally found in your body. And when your levels drop after 20, your skin starts to show it. Here's the science behind why GHK-Cu is the most talked-about anti-aging peptide of the decade.
