Is there anywhere we can buy those clear plastic things that screw into the pen and hold the cartridge? I got one broken and one on its way out.

Bloodwork isn't optional if you're serious about peptide research—it's essential. How do you know what's actually working without data? How do you track thyroid function, hormones, metabolic health, or inflammation markers? You can't optimize what you don't measure. After the holidays when I'm back in Denver, I'm running this comprehensive panel. I always recommend going through your doctor and insurance first—but let's be real, standard panels rarely give you the full picture you need as a biohacker. That's why I've been using AlgoRx for my last two rounds of labs. Their Basic Male Panel covers everything that matters: ✅ Complete hormone panel (Total & Free Test, E2, SHBG, IGF-1, DHEA-S, FSH, LH, Prolactin) ✅ Thyroid function (TSH, Free T3, Free T4) ✅ Metabolic markers (Glucose, Insulin, HbA1c) ✅ Full lipid panel ✅ Complete blood count ✅ Liver & kidney function ✅ Nutrient status This is the baseline you need before starting any protocol, and the data you track during to know what's actually moving the needle. You can also build your own test by test with the build your own panel which I like if you'd only want to check IGF-1. Don't research in the dark. Get your bloodwork done. 👉 Code Derek saves 10% 👉 Male Panel: https://algorx.ai/lab-packages/basic-male-panel-quest?ref=DEREKPRUSKI 👉 Female Panel: https://algorx.ai/lab-packages/intermediate-female-quest?ref=DEREKPRUSKI 👉 Build Your Own Panel: https://algorx.ai/biomarkers?ref=DEREKPRUSKI Questions?
