Simply Peptides:
The Lab

I'm Sarah, the woman behind Simply Peptides: The Lab. I live with Hashimoto's, bipolar I, anxiety, and the changes that come with perimenopause — so fatigue, mental wellbeing, hormones, and weight are deeply personal to me. My own health journey sparked a need to understand the compounds I kept hearing about, the research behind them, and the questions actually worth asking. I built The Lab to make that information easier to explore — my experience alongside clearly sourced research, including what I know and what remains uncertain.

Concentration & syringe calculator
Enter the total amount in the vial, your reconstitution volume, and a prescribed dose to see the concentration and the volume that corresponds to that dose. Syringe markings appear only after you confirm your syringe calibration.
Calculated results
Arithmetic only — not dosing advice. Confirm every calculation with your prescriber or pharmacist before use. Do not treat a vendor worksheet as validated preparation instructions for human use.

What's in my routine — and why I looked into it
These are my personal selections. For each one, I've noted the areas it's being researched for — autoimmune support, inflammation, perimenopause, and weight. These are researched areas, not established treatments, and nothing here treats a condition.
