Every single protocol in our library — all 26 peptides, both signature stacks, no exceptions — requires at minimum a Comprehensive Metabolic Panel before we'll approve it. Patients occasionally ask why we're so strict about this, especially for peptides that seem "low-risk." Here's the real answer.
What a CMP Actually Tells Us
A Comprehensive Metabolic Panel checks kidney function, liver function, electrolytes, and blood sugar — the core systems that process and clear almost everything we prescribe. It's not about assuming something is wrong. It's about confirming, with data instead of a guess, that your body is positioned to handle what you're asking for.
Peptides that seem "gentle" on the surface still interact with real physiology. A peptide that supports tissue recovery still moves through your liver and kidneys. A peptide that affects appetite still interacts with your metabolic markers. There's no category of peptide where skipping this step makes sense.
Why We Don't Make Exceptions
It would be easy to waive the CMP requirement for peptides with a longer track record, or for existing patients we already know well. We don't, for one simple reason: labs change. Someone who was perfectly healthy on their last visit six months ago may not be today, and there's no way to know that without checking. A blanket rule is easier to explain, easier to apply fairly, and — most importantly — it means nobody falls through the cracks because we assumed they were fine.
It's Not Just a Gate, It's a Baseline
The CMP you submit before approval isn't just a checkbox — it becomes the baseline your provider compares against at every retest. Without it, we'd have nothing to measure change against. With it, if something starts drifting three months in, we catch it early instead of after it becomes a problem.
What This Looks Like in Practice
- Order through Fullscript at cost, or email us results if you've had a CMP done elsewhere within the last 12 months
- A provider reviews it before your protocol is approved — not an automated system
- We reuse it as your baseline for the retest schedule built into every protocol
If your CMP comes back with something outside the expected range, that doesn't automatically mean no. It means a provider reaches out to talk through what's going on, what it might mean for the protocol you requested, and what the path forward looks like.
The Bottom Line
A lot of online peptide sellers won't ask you for labs at all. We ask for them every time, for every peptide, because "probably fine" isn't a standard we're willing to prescribe against.
