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.
BPC-157, CJC-1295, Ipamorelin, PT-141, TB-4, GHK-Cu, Sermorelin, full TRT panel. Marek Diagnostics labs. Founded by Derek (MPMD).
Sermorelin, NAD+ $125/mo, TRT from $77/mo annual, Sema $165/mo, Metformin + Rapamycin + Glutathione. 13,900+ Trustpilot reviews. Founded 2015.
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.
Yes — Marek Health offers BPC-157, CJC-1295, Ipamorelin, PT-141, Thymosin Beta-4, GHK-Cu, and Sermorelin. PeterMD offers Sermorelin and NAD+ but not the broader advanced peptide stack.
Yes. PeterMD prescribes Metformin, Rapamycin, and Glutathione as longevity protocols. Marek Health does not currently offer these compounds.
PeterMD is generally more affordable. TRT starts from $77–$99/month annual, NAD+ at $125/month. Marek Health runs $250–$300+/month including the $250 initial consultation and Marek Diagnostics labs.
