Peptides: Marek Health Has a Clear Edge

Marek Health's peptide formulary is the broadest among the clinics reviewed. BPC-157, CJC-1295, Ipamorelin, PT-141, Thymosin Beta-4 (TB-4), and GHK-Cu are all available alongside Sermorelin, TRT, and GLP-1. The platform also pairs peptide protocols with Marek Diagnostics — Quest-partnered labs with 80+ biomarkers, 2,000+ draw locations — for monitoring that matches the protocol depth.

PeterMD offers Sermorelin and NAD+ but doesn't extend into the advanced peptide stack that Marek does. Where PeterMD pulls ahead is in longevity medicine: Metformin, Rapamycin, and Glutathione are available as protocols — compounds Marek Health currently doesn't offer. For patients focused on longevity as much as performance, this is a meaningful distinction.

Who Each Clinic Is Best For

Choose Marek Health If…

  • You want BPC-157, CJC-1295, Ipamorelin, or PT-141
  • Comprehensive lab diagnostics (80+ biomarkers) are important
  • You follow Derek (MPMD) and want his clinic's protocols
  • Complex hormone + peptide stacking is your goal
  • TB-4 or GHK-Cu are on your protocol list

Choose PeterMD If…

  • Longevity compounds (Metformin, Rapamycin) are priorities
  • TRT from $77/month on annual plan appeals to you
  • NAD+ at $125/month is competitive vs Marek's pricing
  • You want a clinic with 10+ years operating history

Final Verdict

This is a genuine close call. Both clinics are premium, physician-led, and well-reviewed. The decision comes down to what you need most.

Choose Marek Health if peptide depth is the priority — BPC-157, CJC-1295, PT-141, TB-4, and Marek Diagnostics are unmatched in telehealth. Choose PeterMD if longevity compounds (Metformin, Rapamycin), more affordable TRT pricing, and a larger established platform matter more to you.
