GHK-Cu Nasal Spray Price Comparison — Verified Vendors & Lab-Tested COAs

What GHK-Cu Nasal Spray Costs Right Now

WPA currently tracks GHK-Cu Nasal Spray from 1 distinct vendor. The cheapest in-stock GHK-Cu Nasal Spray listing is $53.99. Modified Aminos holds the lowest sticker price at $53.99. Normalized to milligrams, GHK-Cu Nasal Spray costs $0.540/mg on this page. The best per-milligram value is the 100mg bottle from Modified Aminos.

GHK-Cu Nasal Spray is stocked in a single size: 100mg bottles. Because bottles of different strengths rarely scale linearly in price, the per-milligram column is the only fair way to rank them.

GHK-Cu Nasal Spray COA Coverage Across Tracked Vendors

1 of the 1 tracked GHK-Cu Nasal Spray listings (100%) are marked as having COA availability in WPA's listing data; this marker is not independent verification. A purity value is recorded for 1 listing; purity alone does not establish identity or independent testing. The recorded purity value is 99.80%. 1 listing records more GHK-Cu in the bottle than the label claims; check the vendor's report and batch before drawing conclusions. The latest COA date recorded in WPA's listing data is 3/26.

To assess a COA, inspect the actual report for the independent lab, test date, and a batch and bottle size matching the GHK-Cu Nasal Spray offer. WPA's listing fields do not establish that a report was independently verified.

How Researchers Actually Dose GHK-Cu

Across 11,744 GHK-Cu calculator runs logged by the WPA community, the most common dose entered is 2mg, most often daily (7x/week). The size researchers calculate against most often is the 100mg bottle (6,448 runs). The most common bacteriostatic water volume is 3mL, which is what sets the draw marks on the syringe for that dose. At that dose a 100mg bottle yields roughly 50 doses, so the bottle size you buy decides how often you reorder as much as the price does.

GHK-Cu Nasal Spray Discount Codes

1 of the 1 tracked GHK-Cu Nasal Spray listing carries a WPA researcher discount code. The largest live discount is 10% off. Every price and per-milligram figure on this page is the post-discount number, so you are never comparing a discounted listing against an undiscounted one. Codes change and some exclude sale items or carry order minimums.

About GHK-Cu

GHK-Cu (copper tripeptide-1) is the copper-bound tripeptide most often sourced for skin-remodeling, hair, and wound-healing research. Research-grade material ships as a lyophilized powder reconstituted with bacteriostatic water; it is also a long-standing cosmetic ingredient.

Its reported half-life is ~1.5 hours, which is the main reason the community cadence above looks the way it does. Copper Tripeptide-1 is a permitted cosmetic ingredient.

How to Read the GHK-Cu Nasal Spray Comparison

• Price per milligram — Every GHK-Cu Nasal Spray listing is normalized to $0.540/mg-style unit pricing, so a small cheap bottle cannot hide a worse real cost than a larger one.
• COA metadata and purity — 1 GHK-Cu Nasal Spray listing is marked for COA availability, and 1 has a recorded purity value. These fields do not independently verify a report.
• Stock status — Live in-stock state for each GHK-Cu Nasal Spray listing, refreshed on a recurring basis.

Reading GHK-Cu Nasal Spray Listings

Nasal spray listings are ranked on total GHK-Cu per bottle, so a lower-priced bottle at a lower concentration can still be the more expensive option per milligram. Where a vendor publishes it, the mcg or mg delivered per spray is what determines how many doses a bottle actually contains.

A nasal spray COA should confirm the active ingredient's purity, and — where available — the preservative system and pH range, which do not appear on a vial COA. Intranasal delivery differs from injection in absorption kinetics, so vial protocols do not carry over.
