Testing / Complete Hormone Panel

For PEG-MGF · IGF-1 Splice Variant · Muscle Repair

Satellite cell activation, documented.

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

Three reasons this panel changes the conversation.

01

PEG-MGF activates satellite cells — but testosterone sets the anabolic ceiling

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

Elevated hs-CRP is the signal that satellite cell activation is suppressed

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

Albumin tells your physician whether the repair substrate will reach the tissue

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.

What's Included

Complete Hormone Panel$249

hs-CRPPost-exercise inflammation — elevated hs-CRP impairs satellite cell activation; PEG-MGF's primary target
Total TestosteroneAnabolic driver of satellite cell response — determines repair ceiling alongside PEG-MGF
Free Testosterone (calc)Bioavailable T — the fraction available for myogenic signalling
SHBGHigh SHBG with low free T blunts the anabolic response to PEG-MGF
EstradiolOestrogen is anti-catabolic and anti-inflammatory — protective during muscle repair
FSH / LHHPG axis — assesses whether testosterone is recoverable or requires upstream support
hs-TSHThyroid — hypothyroidism mimics muscle repair failure with fatigue and weakness
AlbuminNutritional status — low albumin means compromised anabolic substrate delivery
LDL / HDL / TriglyceridesCardiovascular baseline — context for any growth factor protocol
PSAProstate safety screen — standard for any IGF-axis or androgen-adjacent protocol

Common questions

Everything you should know before ordering.

When will PEG-MGF be available to prescribe?

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.

How is PEG-MGF different from systemic IGF-1?

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.

Can PEG-MGF be combined with TB-500?

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.

Is this panel HSA/FSA eligible?

Yes. Physician-ordered diagnostic testing is HSA and FSA eligible. At a 32% bracket, effective cost is approximately $170.
