Relevant biomarkers for peptide use
Upload Your Latest PanelCRP (C-Reactive Protein)CRP is a primary marker of systemic inflammation. Elevated CRP suggests ongoing inflammatory load that healing and immune peptides target directly. Monitoring CRP helps gauge whether anti-inflammatory peptide protocols are working.
IGF-1IGF-1 is the primary downstream marker of growth hormone activity. It rises with effective GH secretagogue use (CJC-1295/Ipamorelin). Monitoring IGF-1 ensures levels stay within the optimal range and helps avoid excess.
Total TestosteroneLow testosterone is a major driver of decreased libido and sexual function. PT-141 acts centrally and does not raise testosterone, but baseline levels inform the full picture. GH peptides may indirectly support testosterone via improved body composition and sleep.
Growth HormoneDirect measurement of GH is useful for establishing baseline before starting GH secretagogues. Note: GH is pulsatile and a single fasting draw may not reflect true output. IGF-1 is a more stable surrogate.
Fasting InsulinGH-stimulating peptides can transiently increase insulin resistance. Monitoring fasting insulin and glucose establishes baseline metabolic health and helps detect any GH-related insulin changes early.
ESR (Erythrocyte Sedimentation Rate)ESR is a nonspecific inflammatory marker that, alongside CRP, helps quantify systemic inflammatory burden. Relevant when using healing or immune peptides to track response over time.
FerritinFerritin reflects iron stores and is also an acute-phase reactant that elevates with inflammation. Low ferritin impairs tissue repair and immune function, making it particularly relevant when using healing or immune-modulating peptides.
