You're doing the work. The weight is responding.
What no one mentioned is that your strength might not respond the same way. If even one of these lands, you're not imagining it.
"I did everything you're supposed to do. I'm still weaker than when I started."
"I love that the weight is coming off. I don't love that the definition is going with it."
"Opening jars used to be my job. Now I leave them on the counter until someone else gets home."
"I keep telling myself I'll build it back when I'm done."
This is the window where strength is easiest to keep. Recognizing it now is the advantage.
When weight drops, your body doesn't just lose fat.
The medication, the deficit, the effort are doing what they should. At the same time, energy availability shifts, hydration changes, and muscle becomes harder to access consistently. Strength feels unpredictable even when nothing in your routine has changed.
The window to support it is while the weight is coming off, not after it's gone.
Five functional ingredients. One purpose.
Creatine Monohydrate
5g
The anchor ingredient. Supports cellular energy and muscle output when energy availability is lower than usual. Strength and muscle support.
Electrolytes
680mg total
When appetite drops, sodium, potassium and magnesium drop with it. Hydration and muscle contraction.
Hydrolyzed Collagen Peptides
5g
The parts of you that change alongside the weight — arms, jaw, inner thighs. Connective tissue, skin, and joint support.
Vitamin C
250mg
Here because the formula needs it to work, not to fill a label. Required for collagen synthesis.
Glycine
500mg
More relevant under the adaptive stress of sustained weight loss. Supports tissue recovery.
What one scoop replaces.
You could buy all five of these separately. The formulation is what you're paying for — which five, at what doses, and what they need from each other to work.

Morgan Crawley
Founder, GLYM Nutrition
When GLP-1 medications became available, my weight changed. But a different problem emerged: as my body shifted, holding onto strength and muscle got harder, and nothing on the market was built to address it.
I hold a B.S. in Biology with a concentration in Human Physiology, with a background in scientific research and medical device development. So I built the thing I couldn't find.
