Authentic copper peptide

Color is right, mass spec is right, reconstitution is clean. Will reorder.

Skin tissue work

Pickart's published sequence. Consistent product across two purchases. Recommend.

blue tint right where it should be

looks like ghk-cu should look. fluorescence assay results were in expected range. happy.

good

blue. high purity. fast ship. simple

ICP confirmed copper loading

ran ICP-OES on the product to confirm Cu content. result was within 5% of theoretical 1:1 stoichiometry. that is genuinely good QC for ghk-cu — many vendors are below 80%

blue blue blue

real ghk-cu the way it should look. some other vendors send something nearly clear and you wonder

Highest copper-loading I've measured in a commercial GHK-Cu

Ran inductively coupled plasma analysis to confirm copper content. Their lot had near-stoichiometric Cu loading, which not all suppliers achieve. Excellent product for serious dermal-research work.

first time buyer, will buy again

easy ordering. arrived in 3 days. blue. high purity. no surprises

blue is real blue

the blue color is intense which is what you want for actual ghk-cu (the copper complex is blue). we've gotten lots from other suppliers that were nearly clear which makes you wonder. this is the real deal.

Rating only — no written review.

Cold pack was warm

By the time the package got to me the gel pack was already room temp. Probably fine for lyophilized stuff but felt like the cold-shipping claim was overstated for cross-country.

no instructions for reconstitution

I had to look up reconstitution myself. Knowledge base has the info but it should be in the box.

Exactly as described

Consistent with the COA. Our collagen synthesis assays showed clear dose-dependent activity. Premium product.

Outstanding copper peptide

The 50mg format is generous. Blue color confirms copper complexation. Purity exceeded expectations at 99.1%.
