The short version
Marek Health is a hormone-optimization service. The first interaction is usually a wide lab panel, and the second is a coach who walks you through the results and recommends a path — often TRT, often paired with ancillary medications, sometimes peptides. The relationship sits at the center of the offering.
Boswell is a peptide-therapy platform. The first interaction is a focused intake about which compound or which goal you're targeting, and the second is a U.S.-licensed physician who decides whether to prescribe. The compound, sourced through a 503A compounding pharmacy, is the unit of value. Members typically arrive having already done their reading.

Different jobs to be done
Marek Health is structured around the question are my hormones where I'd want them, and what should I do about it? The lab panel is the entry point, and the coach translates the numbers into a plan. Hormone work is the core competency: testosterone, thyroid, estradiol management, ancillary support. Peptides exist on the menu, but they sit downstream of the hormone story.
Boswell is structured around the question can I get this peptide protocol prescribed and compounded by people I trust? Members usually walk in already targeting a specific compound — BPC-157 for tissue repair, NAD+ for energy, PT-141 for sexual health, sermorelin for sleep — and want a U.S.-licensed prescriber and a 503A pharmacy in the loop. The peptide menu is wider, the hormone-optimization apparatus is narrower.
If your question is about your hormones, you want a hormone clinic. If your question is about a peptide, you want a peptide clinic.
When Marek Health makes sense
Marek Health earns its place when hormone optimization is genuinely the question. If you're feeling off in ways that map to thyroid, testosterone, cortisol, or estradiol — fatigue, libido changes, body composition shifts, mood — and you want a coordinated team to read the labs and propose a path, the lab-led model is built for exactly that. The coaching layer is real value if you've never had someone interpret a full panel for you.
It's also a reasonable choice if you'd prefer hormone replacement and any peptide work to live under one roof, with one care team. The trade-off is that the menu is shaped by the hormone-first thesis: peptides are present, but they aren't the headline.
When Boswell makes sense
Boswell earns its place when you've already identified the protocol. Maybe a sports doc mentioned BPC-157 for a stubborn tendon. Maybe you've been reading about CJC-1295 + Ipamorelin and want to try it without going through a research-chemicals vendor. Maybe a friend's NAD+ protocol caught your attention and you want a prescription pathway you can trust.
In each case, the value is access to the specific compound — under a U.S.-licensed prescriber, compounded fresh by a 503A pharmacy, with refill oversight and the labeling and accountability that gray-market sources don't provide. The peptide menu is wider than what a hormone-led service offers, and pricing is per-protocol rather than bundled into a coaching membership. If your question is "should I be on TRT," that's a different building. If your question is "can I get sermorelin prescribed by a real doctor," you're in the right place.
Questions worth asking before either
- Is the outcome I'm after primarily a hormone question or a peptide question?
- Do I need a wide lab panel to figure out what's going on, or do I already know what I want?
- Is the prescriber a U.S.-licensed physician, and is the pharmacy a 503A compounding pharmacy?
- How much of what I'm paying is for coaching vs. the medication itself?
- What does follow-up and refill oversight actually look like at month three and month six?
