Common questions

Pre-peptide bloodwork, answered straight.

What bloodwork should I get before starting peptides?

A simple baseline screen. Most people start with a complete blood count, liver and kidney markers, and a metabolic panel (HbA1c, fasting glucose, lipids), then add goal-specific markers. Select your goals on this page to build one combined list to bring to any lab.

Do I need bloodwork before a GLP-1 like retatrutide or tirzepatide?

Many people get a baseline first so they have something to measure progress against. A common GLP-1 baseline covers metabolic markers (HbA1c, fasting glucose, lipids), liver, kidney, and pancreas (lipase). This is general information, not medical advice; talk to a doctor about your situation.

What bloodwork is recommended before TRT or hormone optimization?

A hormone panel (total and free testosterone, estradiol, SHBG, LH, FSH, prolactin), thyroid (TSH, free T3, free T4), plus safety markers: hematocrit from a CBC, PSA for men over 40, liver enzymes, and a metabolic panel. Build the Hormone Optimization panel above for the full list.

How often should I retest while on a peptide protocol?

Many people retest at the end of a cycle, often around 8 to 12 weeks, to compare against their baseline. This is general information, not medical advice; your doctor can set the right interval for you.

Where do I get these tests done?

Any standard lab can run them. Build your panel above, copy the list or message us, and we will help you choose the right baseline and read the results once they are back.

Not sure which panel fits your protocol?

Tell us your goal and we will point you to the right baseline, then help you read the results once they are back. No pressure, no obligation.
