Cellevia Labs KLOW is a four-peptide research formulation combining TB-500 (10mg), BPC-157 (10mg), GHK-Cu (50mg), and KPV (10mg) — 80mg of total peptide content per vial. Each of these peptides has an independent body of preclinical literature spanning tissue repair, dermal remodeling, and inflammatory signaling, and KLOW brings them together in one formulation to give research teams a single, standardized substrate for studying how these pathways may interact.
As with all Cellevia Labs products, KLOW is manufactured and sold strictly for laboratory research use. It is not a drug, supplement, or cosmetic, and it is not approved, evaluated, or intended for use in humans or animals.

Research Profiles
TB-500 (Thymosin Beta-4 Fragment)
TB-500 is a synthetic version of the active region of Thymosin Beta-4, a naturally occurring actin-regulating protein. In published animal and cell-culture studies, the parent protein and its fragment have been investigated for their role in cell motility, angiogenesis, and soft-tissue injury models. Direct TB-500-specific data remains limited compared to the broader Thymosin Beta-4 literature, and researchers frequently note this distinction when designing study protocols.
BPC-157
BPC-157 is a stable pentadecapeptide derived from a sequence found in human gastric juice. It is one of the most extensively studied research peptides in its class, with a substantial body of rodent-model literature examining tissue-healing pathways — including tendon, muscle, ligament, and gastrointestinal mucosal models — along with proposed mechanisms involving growth hormone receptor upregulation and nitric-oxide-mediated angiogenesis. Peer-reviewed reviews consistently note that this evidence base is preclinical; controlled human trial data is not yet established.
GHK-Cu
GHK-Cu is a naturally occurring copper-binding tripeptide first isolated from human plasma. It is the most clinically studied compound in this blend, with human trial data concentrated in topical dermal applications — including collagen and elastin synthesis, fibroblast activity, and skin-remodeling endpoints. Preclinical work has also explored broader tissue and wound-repair pathways. Researchers frequently select GHK-Cu as a reference compound when studying copper-peptide signaling in dermal models.
KPV
KPV is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (α-MSH), studied primarily for its anti-inflammatory signaling activity independent of α-MSH's pigmentation effects. Cell and rodent-model research has examined KPV's interaction with the PepT1 transporter and its downstream effects on NF-κB-mediated inflammatory pathways, with particular research interest in gut-mucosal and dermal inflammation models. As with the other components, human clinical data remains limited.
Why a Combined Formulation
Each peptide in KLOW has been studied independently; a combined 4-peptide formulation allows research teams to investigate potential overlapping or complementary activity across tissue-repair, angiogenic, dermal, and anti-inflammatory pathways within a single, batch-consistent substrate — rather than sourcing and standardizing four separate compounds. Any interactive or synergistic effects between these peptides remain a research question, not an established finding.

Frequently Asked Questions
Is TB-500 the same as Thymosin Beta-4? No. TB-500 is a synthetic fragment representing the active region of the larger Thymosin Beta-4 protein. Much of the published literature refers to the full-length protein rather than the isolated fragment, which is an important distinction for research design.
Has this exact 4-peptide combination been clinically studied? No. Each individual peptide has its own preclinical (and, for GHK-Cu, some human dermal) research base, but the combined blend itself has not been the subject of published clinical trials. KLOW is a research substrate, not a clinically validated formulation.
What purity standard should I expect? Research-grade peptides should be verified by third-party HPLC and mass spectrometry testing, with a Certificate of Analysis available for each batch. Request and review the current COA before use in any protocol.
Can KLOW be used outside of a laboratory research setting? No. This product is labeled and sold strictly for research purposes and is not intended for human consumption, administration, or veterinary use.
