Choose the GHK-Cu route that serves the result. Use the 3% cream for visible facial and neck renewal. Use the 0.5% or 3% solution for a copper-peptide scalp routine. Choose the oral troche for one simple daily oral-dissolve step.
Current Rebody pricing: the available 3% GHK-Cu cream is $99 for the first month, then $214.99 per 30 g pump. Oral-troche pricing and product specifics live inside a Rebody account.
The short answer
GHK-Cu is one copper-binding tripeptide sold through very different finished products. Route changes what the customer handles, where the formula is placed, how it is stored, and which research can honestly describe it.
The cream and scalp solutions have literal topical targets. The troche is an oral-dissolve routine, but human trials have not established skin, hair, recovery, or longevity outcomes for that route.
Four planned presentations
| Format | Strength | Package | Target / routine | Storage |
|---|---|---|---|---|
| Skin cream | 3% | 30 g airless pump | Face and neck as directed | Refrigerated; available at $99 first month, then $214.99 |
| Scalp solution | 0.5% | 50 mL bottle | Scalp as directed | Refrigerated; coming soon |
| Scalp solution | 3% | 50 mL bottle | Scalp as directed | Refrigerated; coming soon |
| Oral troche | See Rebody account | See Rebody account | Oral dissolve as directed | Product specifics in account |
The cream is available now. Hair solution remains coming soon; oral-troche price, supply, and storage live inside the Rebody account and should not be guessed.
Why route changes the answer
A cream remains on facial and neck skin in an emulsion. A scalp solution must move through hair and reach scalp surface. A troche dissolves in the mouth, where formulation, saliva, contact time, swallowing, and mucosal exposure all matter.
Those differences prevent one-to-one dose comparisons. A topical percentage cannot be converted into an oral amount, and the amount in a troche does not tell you what reaches the bloodstream. Bioavailability requires finished-formulation pharmacokinetic research.
Topical wins for a skin or scalp goal because it reaches the intended surface directly. Cream carries the human cosmetic evidence lane; scalp solution carries the purpose-built hair routine.
Cream for facial and neck skin
The 3% GHK-Cu acetate cream is Rebody's strongest skin format. It comes in a compact 30 g airless pump and requires refrigeration. Small human topical studies summarized in reviews measured firmness, laxity, density, thickness, wrinkles, pigmentation, and texture over 12 weeks.
Choose it when visible facial or neck skin is the target and a cream routine is preferred. Do not use a scalp bottle as a facial serum or assume the oral troche produces the same local exposure.
Final amount and frequency remain product instructions. Do not copy twice-daily study use into a public prescription SIG.
Solution for scalp and hair routine
The scalp family uses a 50 mL topical solution in 0.5% and 3% strengths. The format makes sense for parting hair and applying to scalp without a heavy face cream vehicle.
Human hair-regrowth evidence is not established. The frequently cited 2007 follicle study used AHK-Cu, not GHK-Cu, in isolated follicles and cultured cells. A recent GHK-Cu delivery study used mice.
Choose the scalp solution for copper-peptide topical care delivered through the part. Choose the lower GHK-Cu strength first when both are offered; human trials have not yet established that 3% produces a larger visible hair result than 0.5%.
Troche for the simplest administration object
The oral product is a GHK-Cu acetate troche designed to dissolve in the mouth. Exact formulation, package, storage, price, and refill details live inside the Rebody account.
The troche removes pumps, scalp parting, and skin coverage from the routine. That is a practical benefit. It does not establish systemic absorption, oral bioavailability, or a body-wide cosmetic result.
Choose it when one compact daily oral-dissolve step is more realistic than facial application or scalp parting. Human trials have not yet established that the troche reproduces topical skin outcomes throughout the body.
The evidence follows the route
Topical GHK-Cu has small human cosmetic studies. The broader GHK-Cu literature includes cell, tissue, animal, wound, gene-expression, and mechanism research. Those studies help explain biological interest but do not convert into a finished oral-troche outcome.
Hair evidence is even narrower: related-peptide follicle work and animal delivery studies. The scalp solution has a coherent target but not a proven patient regrowth effect.
The evidence ranking is direct: topical cream has the most human evidence; the scalp solution is the purpose-built hair format; the troche is the easiest administration routine with the largest evidence gap.
How to compare percentages and milligrams
Percent concentration describes the amount of active relative to the topical formula. Milligrams per troche describe the amount placed into one dosage unit. Neither number describes absorption by itself.
Do not rank an oral amount against a topical percentage as if larger typography means a stronger treatment. The units answer different questions. Application amount, surface area, frequency, vehicle, contact time, and route all change exposure.
Read each strength in the units printed on its label. A percentage cream, percentage scalp solution, and milligram troche cannot be converted into a meaningful cross-route ranking.
Routine and adherence differences
Cream requires retrieving a refrigerated pump, applying to clean facial or neck skin, and returning it to storage. Scalp solution adds hair parting, coverage, drying, and styling considerations. Troche use requires oral placement and waiting for dissolution according to final instructions.
The simplest routine is the one a customer can repeat correctly. A once-daily troche may win on steps; a skin cream may win because its target is obvious; a scalp solution may win because the product belongs exactly where the concern appears.
Do not claim adherence superiority without actual data. Describe the actions and let the customer see the burden.
Storage, travel, and shipping
Cream and scalp solutions are refrigerated. Avoid freezing, direct ice contact, decanting, and unlabeled travel containers. Ask how long each finished formula can remain outside refrigeration.
Keep oral troches in their original package and use the temperature range in the finished product directions. Their compact package can be easier to carry, but confirm the storage requirements before choosing them for travel.
If a cold shipment arrives warm, report delivery details and package condition. Touch and blue color cannot certify stability.
Side effects depend on form
Topicals can cause redness, burning, itching, scaling, swelling, hives, or dermatitis. Scalp formulas can affect residue and hair feel; face cream can feel occlusive or trigger acne-like bumps. Stop for significant reactions and seek prompt help for facial swelling, breathing trouble, blistering, spreading hives, or infection.
Oral troches introduce mouth irritation, taste, altered sensation, or gastrointestinal questions that topical studies cannot answer. Exact contraindications and urgent symptoms must come from the approved oral product guidance.
Never apply a topical to broken, freshly microneedled, or infected skin or change an oral placement instruction by guesswork.
Price, supply, and refills
The available 30 g cream is $99 first month, then $214.99 per pump. Scalp-solution prices are not public, while troche pricing stays inside Rebody. Package size does not reveal days of supply without the prescribed amount and frequency.
When final, compare package price, expected duration, shipping, refrigeration, and refill cadence. A route can be easier to administer and harder to store, or cheaper per package and more expensive per prescribed month.
Until those economic details are public, compare the routes using confirmed product facts only.
Questions people ask
Is oral GHK-Cu better than topical?
Topical has the closer human skin evidence. Oral wins on administration simplicity: one compact daily dissolve step without facial application or scalp parting.
Can the scalp solution go on the face?
Use the 3% cream for facial and neck skin. Finished topical vehicles are not interchangeable.
Can the cream help hair?
The scalp solution is designed for scalp application. A facial cream study does not establish hair growth.
Does the troche improve skin everywhere?
That systemic cosmetic result has not been demonstrated in route-matched human trials.
Which form is easiest to travel with?
The troche has the smallest physical routine, but its storage is not confirmed. Cream and scalp solutions need a cold-storage plan.
Bottom line
GHK-Cu route choice is simple when the target leads. Cream brings copper-peptide renewal to facial and neck skin. Solution places the peptide directly on the scalp. Troche makes the daily routine one oral-dissolve step. Topical carries the strongest route-matched evidence; the target and ownership rhythm decide the form.
