An adjunct, described honestly.
A weekly compounded lipotropic and L-carnitine injection, prescribed online by US-licensed doctors with the evidence limits stated up front.
L-carnitine has a real and well-characterised job in metabolism: long-chain fatty acids cannot enter mitochondria without it, and that transport step is genuinely rate-limiting. That mechanism is why lipotropic injections have been marketed for decades. What the mechanism does not establish is that adding more carnitine helps someone whose stores are already adequate, and trials in healthy adults report small, inconsistent effects on body composition and performance.
So Peptide12 lists this for what it is — an adjunct for people already training and eating deliberately, prescribed after a clinician reviews thyroid function, kidney function, seizure history, and your other medications. It is reviewed again at 12 weeks rather than continued indefinitely by default. Compounded preparations are not FDA-approved finished drug products, and no one on our care team will tell you this replaces a clinically indicated weight-management protocol.

Frequently asked questions
Not on its own, and you should be wary of anyone who says it will. Trials of L-carnitine supplementation in healthy adults report small and inconsistent effects on body composition. It is prescribed as an adjunct to a training and nutrition plan, and if fat loss is your primary goal, a clinically indicated weight-management protocol is the conversation to have with your clinician.
Oral L-carnitine has limited and variable bioavailability, with much of a dose metabolised by gut bacteria before absorption. Injection bypasses that. Whether the higher exposure translates into a better outcome for you is a separate question your clinician will discuss honestly.
That depends on the medication, which is why intake covers your full list. Thyroid medication, seizure medication, and anticoagulants all warrant specific review, and significant kidney disease usually needs specialist input before starting.
They overlap. Both typically contain methionine, inositol, and choline. B12 MIC leads with methylcobalamin and is most useful when B12 status is genuinely low or poorly absorbed. Lipo-C leads with L-carnitine and targets fatty-acid transport. Your clinician will recommend one rather than both in most cases.
