Description
KLOW Blend — Exclusive Rainbow Peptide Research Formulation
KLOW is Rainbow Peptide’s proprietary research blend, combining four mechanistically distinct compounds targeting interconnected metabolic and neuroendocrine pathways. It is designed for researchers exploring multi-pathway interactions in a single experimental protocol.
Components
- K – Kisspeptin-10 — GPR54 agonist; upstream GnRH regulator; reproductive-metabolic axis sensor
- L – Larazotide — tight junction stabiliser; reduces gut permeability and zonulin-mediated barrier disruption
- O – Orforglipron — oral GLP-1 receptor agonist; non-peptide, first-in-class oral GLP-1R agonist in Phase III trials
- W – Wnt signalling modulator — supports adipogenesis regulation and bone metabolism research
Research Applications
KLOW is formulated for researchers studying the interplay between gut permeability (L), metabolic hormone signalling (O), reproductive-metabolic crosstalk (K), and cellular differentiation pathways (W).
For Research Use Only. Rainbow Peptide supplies the KLOW Blend exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.






Dr. H. Larsen –
KLOW Blend for our multi-target cognitive and anxiolytic research protocol. Each component verified individually in our LC-MS panel. Purity of all components >98%. Excellent blend consistency across two lots.
P. Okonkwo –
Great nootropic research blend. COA clearly separates each component’s purity data. Dissolved cleanly. Our in vitro multi-target receptor panel showed the expected combined profile. Fast delivery.
E. Watts –
KLOW Blend used in our combined peptide research model. Each component confirmed >98%. COA comprehensive. Arrived in good condition with cold pack active. Will reorder for next study phase.
