Lipo-C / MIC + B12 Testing & Verification
Independent, third-party analysis of mail-in Lipo-C (MIC + B12) samples by RP-HPLC-UV — verifying each declared component of the blend individually and reporting measured content per milliliter against the label.
What Lipo-C / MIC + B12 is
Lipo-C, also sold as MIC + B12 or a 'lipotropic' injection, is not a single compound but a compounded blend — typically methionine, inositol, and choline (the 'MIC' trio) plus cyanocobalamin (vitamin B12) in an injectable liquid. None of the components is a peptide: methionine is a single amino acid, inositol is a cyclitol (a sugar alcohol), choline is a small quaternary ammonium compound, and cyanocobalamin is a cobalt corrinoid. We list it here because it is on our test menu. Analytically, the blend spans a wide range: cyanocobalamin has a strong, distinctive absorbance near 361 nm that makes it the easiest component to verify, while the MIC components are weak UV absorbers handled at low detection wavelengths with detection conditions suited to each. Because these products come from compounding operations of highly variable quality, the practical question is rarely 'is this Lipo-C?' but 'is each declared ingredient actually present at its labeled concentration?'
Why get your Lipo-C / MIC + B12 independently tested
- Component omission: the classic failure in compounded blends is a declared ingredient that simply is not there — a label listing four components over a liquid containing two or three. Testing each declared component individually against its own reference standard turns the label's ingredient list into a set of checkable claims.
- Underfill per component: even when every ingredient is present, individual concentrations can fall short of the label (e.g., 25 mg/mL methionine declared, less delivered). Per-component quantitation reports the measured mg/mL for each line so shortfalls are visible ingredient by ingredient, not averaged away.
- B12 as the visible anchor — and the fragile one: cyanocobalamin is both the easiest component to verify (its 361 nm signature) and the one most prone to change, since light exposure converts it toward hydroxocobalamin. Its measured concentration and degradation state say a lot about how the batch was compounded, stored, and shipped.
- Batch-to-batch inconsistency: compounded liquids are made in small lots without the process controls of manufactured drug products, so two vials of 'the same' Lipo-C from the same source can differ. An independent per-component result characterizes the specific vial you send, not the recipe the compounder intended.
What we measure on Lipo-C / MIC + B12
A Lipo-C / MIC + B12 certificate treats the blend as what it is — several compounds sharing one vial — so each declared component is its own line, reported separately. For each component we report identity (retention-time and spectral match against that component's certified reference standard) and measured content per milliliter for comparison against the labeled concentration. Cyanocobalamin is detected at its characteristic absorbance near 361 nm; methionine, inositol, and choline are weak UV absorbers analyzed at low detection wavelengths with conditions suited to each. Because this is a multi-component liquid rather than a single peptide, results are reported as per-component assay / active content (mg per mL), not net-peptide, and a single overall 'purity' percentage is not meaningful for a deliberate mixture — the per-component results replace it.
Every result is issued as a certificate of analysis you — or anyone you forward it to — can verify cryptographically. Reporting identity, purity, and milligram content is the point: a vial can be pure and still underfilled, so we report all three. More on purity vs. net-peptide content and how to read a peptide COA.
Our scope — stated plainly
Testing is RP-HPLC-UV against certified reference standards for each declared component; tell us the full labeled composition and concentrations when ordering so each line can be verified. The MIC components are weak UV absorbers, so quantitation limits are wider for them than for strong chromophores like B12. KMD Analytical is an independent laboratory; we do not perform mass spectrometry, sterility, endotoxin, heavy-metal, or residual-solvent testing — results characterize composition, not the liquid's suitability for injection.
KMD is an independent RP-HPLC-UV lab. We do not run LC-MS / mass-spec, sterility, endotoxin, or heavy-metal testing. If your job needs a capability we don't have, we'll say so.
Lipo-C / MIC + B12 testing — FAQ
You're a peptide lab — can you actually test a MIC + B12 blend?
Yes, honestly and within stated limits. RP-HPLC-UV is not peptide-specific; it applies to any compound we can separate and detect, and each component of this blend is checked against its own certified reference standard and reported as its own line. The one caveat we state up front: methionine, inositol, and choline are weak UV absorbers, so they are analyzed at low detection wavelengths and carry wider quantitation limits than a strong chromophore like B12. We would rather tell you that than pretend every line of a blend certificate is equally precise.
What exactly appears on the certificate for a blend like this?
One line per declared component. Each line reports whether that component was identified (retention-time and spectral match to its reference standard) and its measured concentration in mg per mL against the labeled value. There is no single blended 'purity %' — for a deliberate mixture that number would be meaningless, so the per-component results replace it.
What do you need from me when I send a Lipo-C sample?
The full declared composition: which components the label claims and at what concentrations (for example, methionine 25 mg/mL, inositol 50 mg/mL, choline 50 mg/mL, cyanocobalamin 1 mg/mL). We verify against declared claims, so the more complete the label information, the more complete the certificate. If your blend includes additional declared ingredients beyond MIC + B12, tell us and we will confirm what can be covered before running the sample.
Will this test tell me if the vial is safe to inject?
No. The certificate reports composition — which declared components are present and at what measured concentrations. It does not address sterility, endotoxin, particulates, pH, heavy metals, or anything else about injectability; those require different testing that we do not perform. What it does answer is whether the liquid actually contains what its label claims.
