Pillar 01 · Verifying Authenticity

Verify a Janoshik report at source: use the public Verify tool with the task number and unique key, understand what the check proves, and what it does not.

Pillar 01 · Verifying Authenticity

The questions people bring to Reddit about Janoshik, is it legit, how to verify a report, turnaround, reading results, cost, answered from primary sources.

Pillar 03 · Standards & Accreditation

A reference mapping Australian peptide research in 2026: the TGA regulatory framework, major peptide classes, research institutions, and 2024-26 policy shifts.

Pillar 03 · Standards & Accreditation

A profile of Ozcanium Analytics, an Australian lab offering HPLC purity, LC-MS/MS identity, and GC-MS testing, with a claim-to-COA workflow explained.

Pillar 02 · Purity & Potency

Mass spectrometry peptide analysis confirms a peptide is the correct molecule by matching observed to theoretical monoisotopic mass. What a COA reveals.

Pillar 04 · Stability, Storage & Reconstitution

Bacteriostatic water is water for injection preserved with 0.9% benzyl alcohol. What USP quality, sterility, and the 28-day rule mean for reconstitution.

Pillar 02 · Purity & Potency

Peptide purity testing explained: what an HPLC area-percent figure actually measures, why it is not content or potency, and the limits of that one number.

Pillar 03 · Standards & Accreditation

Residual solvents testing (ICH Q3C classes, TFA and acetonitrile limits, headspace GC-FID) and why it matters for injectable peptides, beyond purity alone.

Pillar 01 · Verifying Authenticity

A Medscape investigation finds patients already dosing unapproved retatrutide. The real issue isn't regulatory: it's product quality with no verification.

Pillar 01 · Verifying Authenticity

Are research peptides safe? Safety splits into identity, purity, endotoxin, sterility, and heavy metals. See how independent lab testing measures each.

Pillar 01 · Verifying Authenticity

Peptide third-party testing decoded: how to tell a genuine, batch-matched independent COA from routine in-house QC and vague, unverifiable on-request claims.

Pillar 03 · Standards & Accreditation

Heavy metals testing means ICP-MS against ICH Q3D limits, not the legacy sulfide test. Why parenteral limits are stricter and why a purity COA omits it.

Pillar 01 · Verifying Authenticity

What to demand from a peptide testing lab: accreditation, HPLC and LC-MS methods, turnaround, sample handling, report transparency, and the red flags.

Pillar 03 · Standards & Accreditation

Sterility testing (USP 71) explained: what membrane filtration and 14-day incubation actually prove, and why a sterile result is not the same as endotoxin-free.

Pillar 01 · Verifying Authenticity

What is Janoshik? A neutral guide to independent HPLC and mass-spec peptide testing, what a Janoshik report contains, and how to verify one is genuine.

Pillar 03 · Standards & Accreditation

Endotoxin testing is the safety gap a purity COA misses. How the USP 85 LAL test (gel-clot, turbidimetric, chromogenic) works, plus route-specific EU/kg limits.

Pillar 01 · Verifying Authenticity

Verify peptide identity, purity, residual solvents, endotoxin, and batch traceability from a COA, and recognise the red flags that mark a fabricated one.

Pillar 03 · Standards & Accreditation

What independent laboratories do for peptide buyers, who the recognised names are, what to ask for, and how a third-party COA differs from an in-house one.

Pillar 02 · Purity & Potency

How reversed-phase HPLC measures peptide purity, what a credible method specifies, and the common pitfalls that distort an area-percent purity result.

Pillar 03 · Standards & Accreditation

What ISO/IEC 17025 accreditation means for a peptide testing laboratory, what its scope statement covers, and how to verify a lab's status independently.

Pillar 04 · Stability, Storage & Reconstitution

How peptides degrade in lyophilised and reconstituted form, what storage conditions do for shelf life, and how ICH Q1A testing supports a shelf-life claim.
