What it is
The same compounded lipotropic injection under a different name, usually with L-carnitine added. The evidence position is identical: none.
Lipo-C is another compounding-pharmacy name for a lipotropic injection. The 'C' generally denotes L-carnitine added to the methionine, inositol and choline base, though as with every product in this category the formulation depends on who mixed it.
It exists as a separate page, not a redirect because people buy it as a distinct product, log it as one, and compare prices between it and 'Fat Blaster' as though they were different interventions. Usually they are not.
The evidence position is the same. No controlled trial has shown that injecting these nutrients produces weight loss in people who are not deficient in them. The addition of L-carnitine does not change that. Carnitine's own weight-loss evidence is weak, and it has its own page here.
How it works
Methionine, inositol and choline as in any lipotropic blend: real roles in methylation, signalling and hepatic fat export, none of which amounts to a mechanism for removing stored fat in a replete person.
L-carnitine transports long-chain fatty acids into mitochondria for oxidation. That is a genuine and essential step. In people with normal carnitine levels it is also not the step that limits fat oxidation. This is why supplementing it does not increase fat loss.
Vitamin B12, where included, is required for energy metabolism. It corrects deficiency and does nothing detectable in someone who is replete.
What it is studied for
Each entry states the evidence behind it. We do not rank indications by effectiveness — for most compounds here, that would be a claim nobody can support.
Weight loss
Published reviewWhat it is sold for.
EvidenceNo controlled trial supports it. Adding L-carnitine to the blend does not change the position, since carnitine's own weight-loss evidence is weak.
Regulatory status
Last reviewed 18 Aug 2026. Positions in this category change frequently, so we date the line.
Not an approved medicine. A compounded preparation, mixed by a pharmacy rather than manufactured as a reviewed product. The FDA does not review compounded preparations for safety or effectiveness before sale.

Dose protocols reported in sources
Displayed for reference only. Every row says where it came from, and a trial protocol and a community convention are not the same kind of information. None of this is fed into the calculator, and none of it is a recommendation.

Start this copies a row into a protocol of your own, which you can then edit. Where a source gave a dose range or an ambiguous frequency, those fields arrive empty — we will not pick a number on your behalf.
CheckRows marked community practice describe what people commonly do, drawn from public discussion. They are not derived from any trial and are not evidence that a dose is safe or effective.
Safety
Reported effects, the situations that need care, and the ones that mean stop.
Reported effects
- Injection site painCommunity practice
Common
- Nausea, and a fishy body odourCommunity practice
Reported
The odour is carnitine, metabolised to trimethylamine. Harmless and socially unwelcome.
- Reactions to an unlisted componentCommunity practice
Unquantifiable
When to stop
- Any allergic response: rash, hives, facial swelling or difficulty breathing. Seek urgent care.
- An injection site that becomes hot, spreading or produces pus.
- Persistent nausea.
Interactions and situations that need care
- Buying it without an ingredient listAvoid
Without the formulation and the amounts you cannot check it against an allergy, a medication or a condition, and you cannot tell whether it differs from a cheaper product under another name.
- Seizure disorderUse caution
L-carnitine has been associated with increased seizure frequency in people with a seizure disorder. Whether a given blend contains it, and how much, is exactly the information usually missing.
- Kidney impairmentUse caution
Carnitine and amino acid loads are cleared renally, and the amounts here are unstated.
- Pregnancy and breastfeedingAvoid
No safety data for a preparation whose contents are not fixed.
What to expect
What the sources describe over time, and how confident anyone can be about it.
HonestlyThere is no human efficacy data for this compound, so there is no evidence-based timeline to give. Any site publishing a week-by-week schedule of expected effects has invented it.
- Substantially the same product as other lipotropic injections sold under other names.
- No controlled trial shows weight loss from injecting these nutrients in replete people.
- L-carnitine's presence is the usual difference, and carnitine's own weight-loss evidence is weak.
- The fishy odour some people notice is carnitine metabolism. Harmless.
- Ask for the written formulation. It is the only way to know what you are comparing.
Storage and combinations
How to keep it, and what it does and does not go with.
Storage and handling
- Freeze-dried powder
- Supplied as a solution. Refrigerated, per the pharmacy's instructions.
- After mixing
- Nothing to reconstitute. Compounded preparations carry a short beyond-use date rather than a manufacturer's expiry.
- Long-term, frozen
- Not applicable.
With other peptides
- Fat Blastercaution
Different names for substantially the same category of compounded lipotropic injection. Buying both means paying twice for overlapping ingredients you have not seen listed.
- L-Carnitinecaution
Most Lipo-C formulations already contain L-carnitine. Taking it separately on top means an unknown total, since the blend does not state its amount.
Checking your vial
Research chemicals carry no manufacturing standard, so what the vial looks like is often the only quality signal available before you use it.
Pink or red solution
The colour is B12, and says nothing about the rest.
No ingredient list or amounts
Ask for the written formulation before paying for a course.
Cloudiness or particles
Discard it.
Vocabulary on this page
- Reconstitution
- Adding liquid to a freeze-dried peptide powder to turn it into a solution that can be drawn into a syringe.
- Blend
- One vial containing several peptides at a fixed ratio, reconstituted and drawn together.
- Injection site
- Where on the body an injection is given. Rotating between sites is standard practice for anything given repeatedly.
- Protocol
- One compound, with a dose, a frequency and a length: the plan, as opposed to what was actually taken.
Questions
- How is it different from Fat Blaster?
- Usually the addition of L-carnitine, and often not even that. Both are compounding-pharmacy names for lipotropic injections, and neither specifies a formula. Comparing them means comparing the written formulations, not the labels.
- Why do I smell fishy after it?
- L-carnitine is metabolised to trimethylamine, which has that smell. It is harmless and it is dose-related.
