Symptom · Muscle loss
Losing strength you used to take for granted.
Muscle loss has three usual drivers — not enough load, not enough protein, and hormones — and they need different answers. The evaluation sorts out which one is yours.

What's often behind it
Age-related loss (sarcopenia)
Muscle mass and strength decline gradually from mid-life; the rate is heavily influenced by resistance training and protein intake.
Weight loss that takes muscle with it
Rapid weight loss — including on GLP-1 medications — can cost lean mass unless protein and training are deliberate.
Low testosterone (men)
A real, lab-confirmed driver of lost muscle and slow recovery — and not the explanation for most people.
Under-recovery
Poor sleep, high stress, and training without rest days stall gains at any age.
Illness, inactivity, medications
A long illness, a sedentary stretch, or certain medications can strip muscle quickly.
The evaluation
What your provider looks at first
History, training and protein habits, sleep, and the timeline of the change — then labs only where they would change the plan.
- ✓Resistance-training frequency and progression
- ✓Daily protein intake, realistically
- ✓Sleep and recovery
- ✓Morning testosterone for men with matching symptoms
- ✓Thyroid and vitamin D where indicated
- ✓Any recent weight loss and how it was achieved
What we may offer, when it's appropriate
The first prescription is usually protein and progressive resistance training. Medication is considered only when a provider determines it fits — and each option links to the evidence.
What we won't do
- —Market anything as a performance or physique product.
- —Offer injected growth hormone — it is federally restricted for this purpose and not recommended by the evidence.
- —Prescribe around a training or protein problem instead of naming it.
Common questions
Can sermorelin rebuild muscle?+
The honest answer: the six-week trial in older men found improvement on specific strength tests but no change in lean mass or body composition. It is a modest, provider-evaluated option, not a shortcut around training and protein. Our evidence review lays out exactly what was measured.
I'm on a GLP-1 and losing strength. Is that normal?+
Some lean-mass loss is common with rapid weight loss of any kind. It is manageable: a daily protein target, two or three resistance sessions a week, and a dose pace your provider adjusts to you. Tell your provider — it changes the plan.
Do you prescribe growth hormone?+
No. Federal law restricts human growth hormone to recognized medical conditions, and a systematic review found it cannot be recommended as an anti-aging therapy. If you have true growth-hormone deficiency, that diagnosis is made by an endocrinologist with stimulation testing.
