Peptide Relay status

Public Alpha

v0.9.0

Building Relay with the community.

Relay is now feature-complete and has entered its first Public Alpha.

From this point forward, improvements are driven by real-world usage, community feedback, analytics, and research rather than internal feature planning.

Thank you for helping shape Relay.

Compound library

Informal four-component blend label

KLOW blend

Not approved; informal blend

KLOW is a community label commonly used for a mixture described as GHK-Cu, BPC-157, TB-500, and KPV. No study was located testing all four together.

Built by the community

Help strengthen the KLOW blend experience record

Every structured report adds useful context about research setup, outcomes, and unwanted effects as the community dataset grows.

Publicly anonymous by default. Your account keeps reports editable and helps reduce duplicate submissions.
Educational research record—not medical advice. Evidence reviewed through July 25, 2026. Peer-reviewed findings, regulatory labeling, sponsor-reported topline results, and unreported registered trials are labeled separately.

Research at a glance

KLOW blend in 60 seconds

Depth and confidence summarize the research record—not effectiveness, safety, or a recommendation.

Research depthNo direct blend program

The available record consists of four separate ingredient records and documented searches that found no exact-combination study.

Why this matters

Research depth describes how large and mature the overall record is. It does not tell you whether the results were positive.

Evidence confidenceVery low for blend outcomes

No direct evidence establishes benefit, synergy, compatibility, stability, safety, or pharmacokinetics for the four-component mixture.

Why this matters

Confidence describes how reliable and consistent the conclusions are. It can be high for one outcome and low for another.

Strongest evidenceSeparate-component studies only; none administered the defined KLOW blend
Why this matters

The strongest evidence type shows what the best-supported conclusions are actually based on.

Human evidenceNo verified direct human KLOW study located
Why this matters

Human findings are more directly relevant than animal or laboratory results, but they still apply only to the populations and outcomes studied.

Route-specific record

What changes by administration method

Route studiedSubcutaneous KLOW mixture as discussed in compounding and community use
Schedules studiedNo controlled human blend schedule located
Amounts studiedNo blend-specific human amount or four-component ratio established
Why this matters

These are exposures used in cited research for a specific route and population—not a suggested amount.

Half-lifeNo human blend pharmacokinetics or half-life; component values cannot be combined
Why this matters

Half-life describes how long it takes the measured amount in the body to fall by half. It is not a dosing recommendation.

Route evidenceNo direct route-specific combination evidence
Why this matters

Evidence can change by administration method. Findings from one route should not automatically be applied to another.

Evidence boundary: Ingredient studies use different routes, formulations, populations, and endpoints. FDA located no human TB-500 or KPV administration, and no component record establishes a SubQ KLOW protocol or safety profile. Amounts shown describe cited research exposure—not a dosage recommendation.

Practical starting point

Why people research it

Common goals and questions—not recommendations or promises of benefit.

  • Skin appearance and repairComponent evidence only
  • Wound and injury recoveryComponent evidence only
  • Gut-inflammation researchComponent evidence only
  • Benefit from the combined blendNot demonstrated

The overview, studies, and source ledger below explain what supports each label—and where the evidence stops.

What the evidence says

What we know—and what we’re still learning

What we know

None for KLOW as a blend. The strongest component-level human evidence comes from specific topical GHK-Cu studies; it cannot establish injectable KLOW.

Why this matters

This is the strongest supported conclusion in the current human evidence—not a summary of every claim made about the compound.

What we’re still learning

The blend's identity and ratio, chemical and physical compatibility, stability after mixing, sterility, pharmacokinetics, interactions, immunogenicity, dose-response, safety, and clinical effects.

Why this matters

Keeping the main uncertainty visible prevents an early or promising finding from looking more settled than it is.

The evidence story

How the research changed over time

Importance shows how much an item changes the evidence story. Quality shows how much confidence the design deserves. A strong negative study can score highly on both.

Why this matters

Importance and quality answer different questions. A rigorous study can be highly important even when it challenges a popular claim.

Exact-combination literature auditChallenges a claim

PubMed search audit for GHK-Cu, BPC-157, TB-500, and KPV combination studies

A July 2026 PubMed audit found no study administering GHK-Cu, BPC-157, TB-500, and KPV together.

Exact-combination trial-registry auditChallenges a claim

ClinicalTrials.gov search audit for GHK-Cu, BPC-157, TB-500, and KPV combination studies

A July 2026 ClinicalTrials.gov audit found no registered study of the exact four-component combination.

BPC-157 Phase 2 registration — not a KLOW studyAdds context

BPC 157 for Acute Hamstring Muscle Strain Repair

No results are posted. The registration cannot establish benefit for BPC-157 or for any blend.

n = 12014-day intervention with assessment through day 56 and recurrence follow-up
TB-500 preclinical evidence — not a KLOW studyAdds context

Simultaneous quantification of TB-500 and its metabolites in in-vitro experiments and rats

Parent TB-500 did not improve fibroblast scratch-wound closure at the tested concentration; one shorter metabolite showed activity.

In-vitro incubations and rat urine collection through 72 hours
Small retrospective report — not a KLOW studyAdds context

Intra-Articular Injection of BPC 157 for Multiple Types of Knee Pain

Fourteen of 16 people reported relief overall. Three of the four people in the two-material subgroup reported relief.

n = 16Follow-up timing was not standardized

Administration and handling

What official research does—and does not—provide

No blend administration evidence

No human trial or approved label establishes a KLOW route, dose, schedule, ratio, or reconstitution process. Published component studies use different formulations and routes, while FDA located no human TB-500 or KPV administration. Those records cannot be combined into guidance.

Four-component stability is unestablished

No published compatibility or stability study was located for GHK-Cu, BPC-157, TB-500, and KPV mixed together. Individual ingredient storage notes cannot establish blend stability, sterility, precipitation risk, aggregation risk, container compatibility, or beyond-use time.
