The collection experience is good but this test is missing key markers needed to understand peptides efficacy particularly IGF -1

Hi Myron, glad to hear you had a good experience and we appreciate your feedback! You’re right that we don’t measure IGF-1. What we do measure are a number of downstream biomarkers that are often impacted by peptide use, things like lipids, inflammation (CRP), thyroid function, and hormone levels. Many people use this to understand how their body is responding over time. For example, individuals using BPC-157 like to track CRP and ferritin, and individuals using GLP-1s are interested in lipids, thyroid, and CRP.
