  • Apitegromab

    Apitegromab is a monoclonal antibody (not a peptide), documented here as a related non-peptide adjunct compound. FDA-approved in September 2026 (brand name Isembyld) for spinal muscular atrophy, and separately shown in a phase 2 trial (EMBRAZE) to reduce lean-mass loss by about 55 percent when added to tirzepatide, an investigational, unapproved use.

  • Bimagrumab

    Bimagrumab (BYM338) is a monoclonal antibody, not a peptide, documented here as a related non-peptide compound because of its role as a muscle-preserving adjunct to GLP-1 weight-loss drugs. Originally a failed Novartis muscle-wasting drug, it is now owned by Eli Lilly (via its 2023 Versanis Bio acquisition) and showed preserved lean mass alongside greater weight loss when added to semaglutide in a published phase 2 trial; it is not approved anywhere, and a related tirzepatide-combination trial was halted early for an undisclosed reason.

  • L-Carnitine

    L-Carnitine is a naturally occurring fatty-acid transport compound with real clinical trial evidence in deficiency, cardiac, and fertility contexts; its popular fat-loss marketing is far more weakly supported.

  • Lipo-B

    Lipo-B is a compounded injectable lipotropic blend (typically methionine, inositol, choline, and B12) marketed by weight-loss clinics; the combination itself has not been clinically validated, and formulations vary by compounder.

  • Lipo-C

    Lipo-C is a compounded lipotropic injectable built on the same MIC base as Lipo-B, marketed as an enhanced variant, though vendors genuinely disagree on whether it adds vitamin C or L-carnitine plus B-complex vitamins.

  • Methylcobalamin (B12)

    Methylcobalamin is an active form of vitamin B12, a well-established, FDA-recognized essential nutrient with strong clinical evidence for deficiency treatment; high-dose "energy shot" marketing to non-deficient users is far more weakly supported.
