Testing / Complete Hormone Panel
For PEG-MGF · IGF-1 Splice Variant · Muscle Repair
PEG-MGF is the PEGylated form of Mechano Growth Factor — an IGF-1 splice variant produced by muscle tissue in response to mechanical load. It activates satellite cells (muscle stem cells) and promotes myofibre repair independent of systemic IGF-1. This panel identifies the inflammatory and hormonal context that determines your baseline repair capacity.

Why it matters
01
MGF stimulates satellite cell proliferation and differentiation. Testosterone drives the final hypertrophic adaptation. A patient with elevated hs-CRP and low free testosterone has impaired repair at two distinct points — this panel identifies both before your physician designs the protocol.
02
Chronic inflammation directly suppresses myosatellite cell function. hs-CRP above 1.0 mg/L in a patient reporting poor muscle repair and recovery is the primary clinical indicator for PEG-MGF. Without the baseline, this pattern is invisible.
03
Hypoalbuminaemia impairs amino acid delivery and anabolic signalling — regardless of peptide dosing. Albumin below 3.8 g/dL alongside muscle repair complaints signals a nutritional barrier that must be addressed alongside the peptide protocol.

Also consider
TB-500 and PEG-MGF are frequently co-prescribed. The Tissue Repair Panel gives your physician the complementary hs-CRP and hormonal picture for both compounds.
Common questions
PEG-MGF is in the FDA formal review pipeline with review expected around February 2027. Testing now establishes your muscle-repair and hormonal baseline — prescribing can begin immediately when the review concludes.
Systemic IGF-1 acts body-wide and carries significant off-target risk — including tumour growth promotion. PEG-MGF is a locally-produced splice variant that acts specifically on satellite cells at the site of mechanical stress. The PEG (polyethylene glycol) conjugation extends its half-life without increasing systemic exposure — making physician-managed dosing practical.
Yes — TB-500 and PEG-MGF target complementary repair mechanisms. TB-500 (Thymosin Beta-4) promotes actin polymerisation and vascular repair; PEG-MGF activates satellite cell proliferation. The two are frequently co-prescribed for patients with tendon, joint, or muscle pathology alongside poor recovery. Both require the same panel.
Yes. Physician-ordered diagnostic testing is HSA and FSA eligible. At a 32% bracket, effective cost is approximately $170.
