KLOW

Actual products may vary slightly from the images shown on this website.

KLOW is a research blend of GHK-Cu, BPC-157, TB-500 and the tripeptide KPV. It is investigated for the skin-matrix, tissue-repair and modulatory pathways the four compounds engage.

Batch Consistency

Automated synthesis pipelines ensure uniform molecular sequences across all production runs.

The Research

Component-level research for the KLOW blend

KLOW combines GHK-Cu, BPC-157, TB-500, and KPV; its research page should map the components clearly without implying the four-part blend has an established literature.

The Cold Guarantee

Guaranteed pharmacy-grade cold, held end to end.

COLD CHAIN GUARANTEED ★ COLD CHAIN GUARANTEED ★
  1. Cold Origin

    Chilled at release

    Chilled within the hour it clears lot release. Never sits warm on a bench.

  2. Cold Vault

    Logged 2–8 °C room

    A temperature-logged 2–8 °C room, not a consumer fridge, logged around the clock.

  3. Cold Pack-Out

    Phase-change packed

    Packed into insulated, phase-change coolers minutes before pickup, not hours.

  4. Cold Transit

    Rerouted on heat

    Held or rerouted when forecasts spike. We’d rather delay a day than ruin a vial.

Common questions

What purity level are your peptides and how is it verified?

Vivo requires a minimum purity of 99%. If a production lot does not meet that threshold, we do not release it. Every lot undergoes independent third-party verification before release, including identity confirmation, purity analysis, potency quantification, and endotoxin testing.

What is a Certificate of Analysis (CoA) and how do I read it?

A CoA is a verified report from an independent laboratory documenting the material in one specific production lot. Start with the lot number, then review the identity, purity, potency, and endotoxin results. The report also lists the analytical methods and the laboratory responsible for verification.

Where are your peptides made?

Every Vivo peptide is synthesized, tested, and filled in California, and each released lot is tied to its own batch-specific Certificate of Analysis.

How should I store peptides?

Store unopened vials in a cool, dry place, protected from direct light, heat, and moisture. Refrigeration is not required while the product remains lyophilized. After reconstitution, keep vials refrigerated.

How fast do you ship and is cold shipping required?

Orders placed before 10:00 a.m. Pacific Time on business days are dispatched the same day, by UPS 2nd Day Air as standard, with UPS Next Day Air available at checkout. Shipping is complimentary on orders over $200. Lyophilized products do not require refrigeration in transit, but we cold-pack every order as an added measure against heat and humidity.
