Recovery & cellular-wellness multi-peptide blend
Overview
KLOW is a multi-peptide complex formulated as a synergistic blend studied in recovery, longevity, and cellular-wellness research contexts. Like GLOW, it is supplied as a single co-lyophilised cake so the formulated ratio between components is preserved in the released vial. KLOW is a defined proprietary blend rather than a single molecule, so the released-batch COA characterises it by HPLC profile and MS; total peptide content (specification ≥95.0%), peptide-profile mapping by LC-MS, molecular-weight distribution, water, endotoxin, heavy metals, residual solvents and microbial limits are available on request and listed on the COA when tested. Exact composition is proprietary and can be disclosed under NDA to qualified B2B accounts.
Applications & buyer fit
Custom-blend buyers are almost always OEM clients building a branded product around a specific ratio of two or more peptides. The development workflow is collaborative: ratio target, analytical method to verify it, stability protocol in the chosen carrier, and packaging selection are all defined in the OEM brief before the first commercial run. Sample-stage volumes are usually 5-10 g of finished blend; commercial MOQ depends on the components.

Frequently asked questions
Both are proprietary co-lyophilised multi-peptide complexes, but they are formulated for different research contexts: GLOW is studied around skin-health and radiance, while KLOW is studied around recovery, longevity, and cellular wellness. Each ships as a single co-lyophilised vial with a released-batch COA verifying total peptide content and peptide-profile mapping. Exact component composition for either blend is proprietary and shared under NDA.
The component peptides and ratios are held as proprietary and are not printed on the public COA. Documented composition disclosure can be arranged under NDA for qualified B2B accounts (distributors, formulators, and labs qualifying a supplier). The public COA still verifies the blend by total peptide content (≥95.0%), LC-MS peptide-profile mapping, and molecular-weight distribution.
Send any vial from your order to an independent laboratory of your choice. If the report shows the product does not meet the specification on its COA — purity below the stated minimum, or an identity that does not match — share the report with our sales team and we refund that product in full.
