How peptide therapy actually works
From a blood draw to a protocol: the labs-first model that turns peptide hype into a clinical plan.

The internet sells peptides as a shopping list. Real therapy is the opposite — it starts with measurement. The question isn’t “which peptide is best” but “what do your labs and goals say you actually need?”
Here’s the sequence a responsible program follows, and why each step exists.
Step 1 — Baseline labs
A focused panel reads the systems peptides touch: the growth-hormone axis (IGF-1), inflammation (hs-CRP), metabolic markers (HbA1c, fasting glucose and insulin), thyroid, and liver function. These aren’t trivia — they decide whether a protocol is appropriate and safe.
For example, an elevated liver enzyme (ALT) can make growth-hormone-axis peptides a poor first choice until it’s worked up. You only know that if you measured it.
Step 2 — Clinician review + matching
A clinician reads the labs against your goals and history, rules out contraindications, and matches a protocol. At Meto an engine pre-reads the panel and drafts a recommendation, but a licensed clinician signs every prescription — the human makes the call.
Step 3 — Protocol, titration, and re-checks
Most protocols start low and build, so your body adapts and side effects stay minimal. Then you re-test. The week-12 lab isn’t a formality — it tells the clinician whether the protocol moved the marker it was meant to, and whether to hold, adjust, or stop.
- Start low, titrate up — adaptation beats shock.
- Re-check labs on a schedule, not a hunch.
- Adjust to outcomes; a protocol is a hypothesis, not a verdict
