VitaPep formula comparison
Compare the facts that actually change from one VitaPep formula to the next: peptide identity, listed amount, carrier, applicator, testing, and how closely published research matches the finished topical product.
Start here
GHK-Cu is the clearest fit in the current VitaPep range. Its cosmetic research context includes smoother- and firmer-looking skin, but that does not guarantee an individual result from the finished VitaPep formula.
Choose the exact molecule and form you intended to compare: BPC-157 Arginate, KPV, the TB-500 fragment, or PT-141. Similar research themes do not make those peptides interchangeable.
Current records list 70% DMSO and 30% deionized water for GHK-Cu, KPV, TB-500, and PT-141. DMSO supports topical-delivery context; it does not prove a peptide-specific absorption level.
None of these cosmetic serums should be selected as a treatment for an injury, disease, pain, inflammation, or another medical condition. Discuss those goals with a qualified health professional.
Side-by-side
| Formula | Listed amount | Carrier | Applicator | Evidence context |
|---|---|---|---|---|
| GHK-Cu | 14 mg / 30 mL | 70% DMSO / 30% deionized water | Follow the applicator supplied with the current bottle | Substantial laboratory literature, limited and mixed human topical evidence, and no controlled study identified for the finished VitaPep formula. |
| BPC-157 Arginate | 6.1 mg listed formula input / 30 mL | Review the current product ingredient declaration | Serum pump or 1 mL dropper | Research is overwhelmingly preclinical or uses non-topical preparations; no comparable controlled finished-product human study was identified. |
| KPV | 10 mg labeled amount / 30 mL | 70% DMSO / 30% deionized water | Follow the applicator supplied with the current bottle | Cell-signaling and specialized skin-delivery studies provide research context; they do not establish a result from ordinary use of the finished VitaPep formula. |
| TB-500 | 1.2 mg / 30 mL | 70% DMSO / 30% deionized water | Serum pump or 1 mL dropper | TB-500, its metabolites, and full-length thymosin beta-4 have different evidence. No comparable controlled topical human study was identified. |
| PT-141 | 25.5 mg / 30 mL | 70% DMSO / 30% deionized water | Follow the applicator supplied with the current bottle | Published clinical evidence for prescription bremelanotide concerns a different formulation and injection route; it does not establish topical outcomes. |

Formula by formula
GHK-Cu
The most appearance-focused formula in the current range. GHK-Cu is used in cosmetic skin-conditioning contexts associated with smoother-, firmer-looking skin, while finished-product results remain formulation-specific.
BPC-157 Arginate
For shoppers seeking the specifically identified Arginate form in a ready-to-use, localized external cosmetic format with no mixing or reconstitution.
KPV
For shoppers specifically comparing KPV topical formats, disclosed carrier composition, and batch-specific measurement—not a promise to treat inflammation or a skin condition.
TB-500
For shoppers seeking the specifically identified seven-amino-acid TB-500 fragment in a measured external format—not full-length thymosin beta-4.
PT-141
For shoppers specifically comparing a PT-141 external cosmetic format. It is not interchangeable with, or evidence-equivalent to, a prescription injectable product.
Testing transparency
A raw-material identity or purity result answers a different question from finished-serum peptide content, microbiological quality, or heavy-metal testing. Match the report to its sample, batch, date, method, units, and scope.
Testing documents describe the submitted sample and measured characteristic. They do not prove a cosmetic result, medical benefit, or identical result for every batch.
