What it is
PEG-MGF is a pegylated splice variant of IGF-1 expressed in muscle after mechanical loading.
How it works
It is proposed to support satellite-cell activation following resistance training.
Why it may be considered
Rarely prescribed. The human evidence is minimal and the training stimulus itself remains the dominant variable.
Who may be a candidate
- You are an established MECCA patient, or are willing to begin with a consultation.
- You have a clearly defined goal that this therapy plausibly addresses.
- Your recent laboratory work and history have been reviewed by your clinician.
- You are able to attend the monitoring intervals the protocol requires.
Who may not be a candidate
- You are pregnant, breastfeeding, or planning pregnancy.
- You have an active malignancy or an unresolved undiagnosed symptom.
- You take a medication that interacts with this therapy.
- Your goal is better served by training, nutrition, sleep or an existing prescription.
Typical treatment-review considerations
- Current medications, supplements and prescriptions written elsewhere.
- Relevant baseline testing, and whether an interval draw is needed first.
- Monitoring cadence, expected review date and the criteria for stopping.
- Whether a non-pharmacologic route addresses the same goal first.
Safety considerations
- Prescription-only. Never self-source or self-administer outside a supervised plan.
- Injection-site reactions, bruising and transient discomfort are the most commonly reported effects.
- Report any new or unexpected symptom to your care team before the next scheduled dose.
Frequently asked
About PEG-MGF.
You can submit a request, but it cannot be approved until a licensed clinician has reviewed your history. If you are not yet a patient, your request opens a consultation rather than a prescription.
No. Pricing is released with your approved plan, after a clinician has decided the therapy is appropriate for you.
Often, yes. A request tells us what you are interested in. The recommendation you receive reflects your goals, history, medications and testing.

How we think about safety.
Prescription therapy carries risk. We name the monitoring a therapy requires, the symptoms that should stop it, and the criteria for reviewing it again.

Measure, interpret, intervene, re-measure. Nothing is prescribed without a baseline, a defined goal and a scheduled point at which the plan is revisited.
Learn our approach →What happens after you request.
