Is the Peptide Protocol Builder medical advice?

No. The Protocol Builder is an educational research tool. It generates suggestions based on peer-reviewed dosing literature and our COA verification database. Always coordinate any peptide use with a licensed clinician — especially if you are pregnant, have a cancer history, take prescription medications, or have a chronic condition.

How long is a typical peptide cycle?

Most peptide cycles run 8–12 weeks. Recovery stacks (BPC-157, TB-500) are often 4–8 weeks until the underlying issue resolves. GH-axis peptides like CJC-1295 + Ipamorelin are commonly cycled 8 weeks on, 4 weeks off. The Protocol Builder lets you choose 4-week, 12-week, or 6-month horizons and phases the stack accordingly.

What lab tests should I run before starting peptides?

It depends on your goal. For weight loss: HbA1c, fasting glucose, lipid panel, TSH/free T4. For recovery: hsCRP, vitamin D, magnesium, zinc. For energy/sleep or anti-aging: IGF-1 (especially if running GH-axis peptides), morning cortisol. For libido: total and free testosterone, SHBG, estradiol. For fertility prep: AMH, FSH, estradiol, vitamin D, ferritin, TSH, prolactin — and discuss everything with your reproductive endocrinologist before any cycle.

How do I verify the peptide I buy is legitimate?

Always check the Certificate of Analysis (COA) for the specific batch you receive. PeptidesRated tracks verified COAs across 200+ vendors at /coa. The Protocol Builder routes to vendors we have COA data on, but you should still verify the exact batch number against the COA before using.

Does the Protocol Builder require an account or email?

No. The Protocol Builder is free and requires no signup. Your answers are not stored on our servers. You can take a screenshot of your protocol or copy the text to share with your clinician.

What is n-of-1 peptide therapy?

N-of-1 means a treatment designed for a single patient rather than a population. Compounded peptides are inherently n-of-1 — a 503A pharmacy compounds for one patient at a time, based on a clinician’s prescription. The Protocol Builder helps you research what an appropriate n-of-1 starting point might look like before that conversation.
