In this promotional monologue, Katie Mullen stresses that anyone using peptide supplements must monitor their blood biomarkers, otherwise they are "flying blind" and wasting money. She explains that peptide effectiveness depends on having hormones, inflammation levels, and heart health markers within optimal ranges. To address this, she uses Rhythm’s at‑home blood test, which arrives monthly by mail and lets her track over 20 biomarkers—including hormones, inflammation markers, and heart‑health indicators—without needles, doctors, or appointments. After a quick two‑minute collection, she can drop the sample at a FedEx location or request a home pickup via text. Results are delivered to her phone within about 72 hours. Mullen frames the service as an easy, cost‑effective way to ensure peptide regimens are working as intended.

Guys, if you're doing these, you have to be doing this. If you're doing peptides and you're not getting your bloodwork done, you are absolutely guessing and you are wasting your money. Peptides only work if everything and your blood markers are all dialed in. You could be on the most perfectly protocoled stack of peptides, but if your inflammation is through the roof and you have no idea, or your hormones are out of whack, you are absolutely not going to get the results that you think you are. That's why I do this at home now. This is the Rhythm at-home blood test. Every month it comes in the mail and I can track over 20 biomarkers, hormones, inflammation markers, my heart health, to make sure that all the things I'm doing for myself is working in my favor. Okay. It takes me 2 minutes. There's no needles, no doctors, no appointments, and it comes to my house every single month in the mail. And when I'm done, I go drop it off at FedEx, or if I don't have time to do that, I can literally text them and they'll come pick it up at my house. So easy. And I get my results in like 72 hours on my phone. If you're spending real money on peptides but you're not tracking what they're actually doing, you are flying blind and you're wasting your money.
