A 10 mL vial of Lipo-C costs $58 at EZ Peptides, $59.99 at Mile High Compounds and $79 at Ion Peptide, and Nura Peptide sells a 30 mL MIC B12 vial for $78 — about $26 per 10 mL (list prices checked October 22, 2026). But these vials do not hold the same formula, and only some of them contain B12. That is the whole buying problem with Lipo-C: the name is a market label, not a recipe.
Lipo-C is a lipotropic injection blend, not a peptide. It is a premixed solution of nutrients — typically L-methionine, choline and L-carnitine, often with vitamin B12 and other B vitamins — sold by peptide vendors next to their peptide catalogs. This guide compares what each vendor's own lab report says is in the vial, per mL, what each costs, and what the published research does and does not support. For the live ranked comparison, see Best Lipo-C Vendors.
Research-context information only. Lipo-C is a lipotropic nutrient blend, not a peptide, and the combined blend is not an FDA-approved drug product; research-grade vials sold by peptide vendors are labeled "not for human consumption." Contents, prices, and reactions reported below come from vendor lab reports, published research, and self-reported community sources. This article reports what has been documented, not what should be done. Consult a licensed physician for personal medical decisions.
Understanding Lipo-C Pricing
Lipo-C prices cluster tightly — every product here is a single vial at $58-$79 list — so the sticker price is the least informative number on the page. What separates the products is the formula: which nutrients are in the vial, at what concentration, and whether a lab has measured them.
Current Market Pricing (2026)
| Vendor | Product | Format | List price | Stock (Oct 22) |
|---|---|---|---|---|
| EZ Peptides | LIPO-C with B12 10ml | 10 mL liquid solution | $58.00 | In stock |
| Mile High Compounds | Lipo-C | 10 mL liquid solution | $59.99 (was $69.99) | In stock |
| Ion Peptide | Lipo-C Burn Blend – 526mg | 10 mL vial, lyophilized per its COA | $79.00 | In stock |
| Ion Peptide | LIPO-C + B12 (Methylated) – 10mg | 10 mL liquid solution per its COA | $79.00 | Out of stock |
| Nura Peptide | AdrenaLean (MIC B12) | 30 mL liquid solution | $78.00 (about $26 per 10 mL) | In stock |
The pattern: per mL, Nura's 30 mL MIC B12 vial is the lowest list price here at roughly $2.60/mL, against $5.80/mL for EZ. Among the 10 mL vials, EZ and Mile High sit within $2 of each other, yet one lab report lists B12 and the other does not. Ion's B12 version is the only one of the four with a lab report confirming B6 (pyridoxine) alongside B12 — and it is the one that is currently out of stock.
EZ Peptides lists quantity pricing on the product page (5% off at 5 vials, 10% off at 10), and Ion Peptide runs quantity tiers as well. Vendor discount codes change; the live block below and the Best Lipo-C Vendors page carry the current figures.
What Each Vendor's Lab Report Lists (per mL)
| Ingredient | EZ Peptides (Janoshik #171647) | Mile High (Chromate #30225) | Ion LIPO-C + B12 (Kovera, lot LC12-04142026) |
|---|---|---|---|
| L-carnitine | 78.61 mg/mL | 50.62 mg/mL | Present (identity only) |
| L-methionine | Not tested | 10.41 mg/mL | Present (identity only) |
| Choline | Not tested | 56.74 mg/mL (choline chloride) | Present (choline bitartrate) |
| L-arginine | 21.39 mg/mL | Not listed | Present (identity only) |
| Methylcobalamin (B12) | 1.45 mg/mL | Not listed | Present (identity only) |
| Hydroxocobalamin (B12) | 0.22 mg/mL | Not listed | Not listed |
| Dexpanthenol (B5) | Not tested | 4.78 mg/mL | Present (identity only) |
| Pyridoxine (B6) | Not tested | Not listed | Present (identity only) |
| Inositol | Not tested | Not listed | Not listed |
"Not tested" means the vendor's report did not measure that ingredient — not that it is absent. "Not listed" means the report names a full ingredient panel and that ingredient is not on it.
Two things stand out. First, none of the three published reports lists inositol, the "I" in the classic MIC (methionine, inositol, choline) lipotropic formula, so Lipo-C and MIC + B12 should not be treated as the same product. Nura Peptide's MIC B12 is the one product here labeled with all three — methionine, inositol and choline — plus cyanocobalamin (B12); its lot certificate is not published on the product page, so its amounts per mL are not shown in the table above. Second, L-carnitine is the one ingredient all three reports list, which fits the common reading of the "C" in Lipo-C.
Ion's Lipo-C Burn Blend is the outlier: its product page gives no ingredient list and does not mention B12, and the page of its COA we could access (ILS Laboratories, lot FB526-05202026) reports "526mg" labeled content in a lyophilized 10 mL vial without naming the components.
How to Verify Lipo-C Quality
For a single peptide, a COA answers one question: is this the molecule on the label, and how pure is it? For a multi-ingredient blend, a COA has to answer several — and a "99% purity" headline cannot describe a solution of five or seven different nutrients. The useful number is the measured concentration of each ingredient in mg/mL.
What a Lipo-C COA Should Include
Identity and quantity, ingredient by ingredient
- Each named ingredient identified (HPLC or LC-MS) and quantified in mg/mL
- The B12 form named explicitly — methylcobalamin, hydroxocobalamin and cyanocobalamin are different molecules
- Results compared against a stated specification (Mile High's report shows choline at 56.74 mg/mL against a 50 mg/mL spec, flagged +13.5%)
Sterility and contamination
- Endotoxin (LAL) result — Mile High reported <0.25 EU/mL, Ion's LIPO-C + B12 reported <0.10 EU/mL
- Microbial or sterility screen — both of those reports show no growth
- Heavy metals screen
Traceability
- A batch or lot number that matches the vial
- A test date and a verification code at the testing lab
How to Verify a COA Is Legitimate
- Third-party lab — the three reports above come from Janoshik, Chromate and Kovera Labs; Ion's Burn Blend COA comes from ILS Laboratories
- Verifiable report number at the testing lab's own site (EZ's Janoshik report carries a verification key; Mile High's Chromate report carries an access code)
- Recent date — Mile High's lot was analyzed December 2025, EZ's June 2026, Ion's LIPO-C + B12 April 2026
- Batch match between the report and the vial label
- Ingredient panel match — the report should cover the ingredients the product claims, not just one of them
Red Flags to Avoid
- A single "purity" percentage for a multi-ingredient blend, with no per-ingredient figures
- "With B12" in the name but no B12 on the lab report
- No ingredient list anywhere on the product page or COA
- Prices far below the $58 floor for a 10 mL vial
- No batch number linking the vial to a test
- Cryptocurrency-only checkout with no contact information and no reship policy
