Copper Peptides for Hair Growth - Ultrastrong 10% GHK-Cu Copper Peptide Serum for Hair with 7x Absorption - MADE IN USA

I’ve been using Sonora Supply Co.’s Copper Peptides for Hair Growth for a while now, and the results have been fantastic! The 10% GHK-Cu formula is truly ultra-strong, and I’ve noticed a significant improvement in my hair’s thickness and overall health. The 7x absorption technology makes a difference—I can tell it’s penetrating deeply and working effectively.It’s also great to know that it’s made in the USA with high-quality ingredients. The serum absorbs quickly, doesn’t leave any greasy residue, and has been easy to incorporate into my routine. If you’re looking for a powerful, science-backed solution for hair growth, this is the one to try. Highly recommend!

Very pleased with this product. After only about 3 weeks of use, I've notice increase shaft density and even some new growth beginning at the vortex. Product absorbs quickly and is non-greasy. I even used this on my face following some sunburn/ sun exposure in florida and it literally healed overnight...will definitely continue ordering!

The most potent GHK-cu product on amazon, works wonders, great for skin and hair

I saw strengthening of hair in one week. I saw new growth after one month. Can't wait to see what it looks like in 3-4 months! Great product.

So far it’s been a month. I see more baby hair growing so far so good. Just be mindful that everybody is different.

Easy to use

Feels good on the skin and absorbs quickly with no odor or film.

I've been using this copper peptide serum for a few weeks, and it’s already showing results. Just a few drops massaged into my scalp each night, and I’ve noticed my hair looking thicker and healthier. The texture is perfect—it absorbs quickly without any greasy residue, which is great for morning or nighttime use. I love that it’s made in the USA and has no fillers. So far, this is a good hair growth products I've tried.
