The Claim

High-quality human randomized controlled trials (RCTs) have not been conducted to evaluate the efficacy or safety of the peptides BPC-157, Ipamorelin, and CJC-1295 for any claimed benefits including recovery, sleep, or body composition.

Description
1 study reviewed
In plain English

Scientists haven't done proper human tests to see if certain peptide supplements like BPC-157, Ipamorelin, or CJC-1295 actually help with recovery, sleep, or body composition.

See the scientific wording

No high-quality human randomized controlled trials exist for peptides including BPC-157, Ipamorelin, and CJC-1295 for any purported benefits such as recovery, sleep, or body composition

What the research says

1 study

  1. Study: Reply to Sikiric et al. BPC 157 Therapy: Targeting Angiogenesis and Nitric Oxide’s Cytotoxic and Damaging Actions, but Maintaining, Promoting, or Recovering Their Essential Protective Functions. Comment on “Józwiak et al. Multifunctionality and Possible Medical Application of the BPC 157 Peptide—Literature and Patent Review. Pharmaceuticals 2025, 18, 185”

    This study is about BPC-157 but it's not a human randomized controlled trial - it's a reply letter discussing the peptide's mechanisms. The claim says such human trials don't exist for these peptides, and this study doesn't provide one, so it supports rather than contradicts the claim.
