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 at 2 verified vendors. In-stock GHK-Cu Nasal Spray bottles run from $32.50 to $53.99 — a 1.7x spread for the same compound. Ascension Peptides holds the lowest sticker price at $32.50. Normalized to milligrams, GHK-Cu Nasal Spray costs $0.325/mg to $0.540/mg on this page. The best per-milligram value is the 100mg bottle from Ascension Peptides.

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.

Ranked by true cost per milligram, the GHK-Cu Nasal Spray listings WPA tracks are: Ascension Peptides — 100mg at $32.50 ($0.325/mg), COA purity 99.23%; Modified Aminos — 100mg at $53.99 ($0.540/mg).

GHK-Cu Nasal Spray COA Coverage Across Tracked Vendors

2 of the 2 tracked GHK-Cu Nasal Spray listings (100%) publish a third-party Certificate of Analysis. Assayed purity on those reports is 99.23%. 2 listings report more GHK-Cu in the bottle than the label claims, which lowers the real cost per milligram below the printed price. The most recent GHK-Cu Nasal Spray COA on file is dated 6/26.

A COA is only worth what it proves: it has to name the independent lab, be dated within the last 12 months, and match the exact GHK-Cu Nasal Spray batch and bottle size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose GHK-Cu

Across 8,559 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 (4,591 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

2 of the 2 tracked GHK-Cu Nasal Spray listings carry a WPA researcher discount code. The largest live discount is 50% 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 $0.325/mg-style unit pricing, so a small cheap bottle cannot hide a worse real cost than a larger one.
• COA status and purity — The 2 COA-backed GHK-Cu Nasal Spray listings show assayed purity and test date so quality is a number, not a claim.
• 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.
