What did @iamalmaramirez actually say?
The creator posted a "shot day" update, reporting she lost 13 pounds since starting tirzepatide eight weeks after giving birth. She said her starting weight was 181 pounds, her current weight is 176 pounds, and her goal is 145 to 150 pounds. She also said she gets her medication from a compounding pharmacy called IVRX, which delivers to her home and uses its own prescribing doctor. One specific claim stood out: she said she injects in the arm because it gets the drug to her system "faster or more efficiently" than the leg or stomach.
There is also a math problem here that nobody seemed to catch. If she started at 181 and is now at 176, that is a 5-pound difference, not 13 pounds. She stated both numbers in the same video. At least one of them is wrong, and that discrepancy matters when someone is watching this as a weight-loss reference.
Does the science back this up?
Tirzepatide is a dual GIP/GLP-1 receptor agonist, and the clinical evidence for weight loss is genuinely strong. However, postpartum use introduces real variables that the research has not fully addressed.
The SURMOUNT-1 trial (Jastreboff et al., 2022, New England Journal of Medicine) showed tirzepatide at 15 mg produced a mean weight reduction of about 20.9% over 72 weeks in adults with obesity. That is a serious effect size. But SURMOUNT-1 excluded breastfeeding individuals, and the creator did not clarify whether she is nursing. That matters because tirzepatide's safety profile during lactation is not established. The FDA label explicitly notes that data on use while breastfeeding is absent.
Eight weeks postpartum is also early. The American College of Obstetricians and Gynecologists recommends waiting until at least six weeks postpartum before initiating weight-loss interventions, and even then, the guidance is conservative when breastfeeding is involved. None of this makes her experience invalid, but the context she left out is clinically relevant.
What did they get wrong (or right)?
The injection site claim is where the science gets interesting, and not in the creator's favor. She said the arm gets tirzepatide to the system "faster or more efficiently." There is limited pharmacokinetic data specifically on tirzepatide injection site differences. What exists for GLP-1 class drugs more broadly, including semaglutide studies, does not consistently show the arm to be meaningfully superior in bioavailability compared to the abdomen or thigh. The prescribing information for Mounjaro and Zepbound lists the abdomen, thigh, and upper arm as interchangeable sites with no stated preference. This claim appears to be anecdote or gym-culture lore, not pharmacology.
What she got right: framing medication-assisted weight loss as "not the easy way out" is fair. The SURMOUNT clinical data makes clear that tirzepatide works alongside significant metabolic and behavioral changes, not instead of them. Reducing stigma around GLP-1 use is a legitimate public health goal.
The math error is a real credibility problem. If you are going to post a weight update, the numbers need to be consistent.
What should you actually know?
A few things deserve direct attention if you are considering something similar after this video.
- Compounded tirzepatide is not the same as FDA-approved Zepbound or Mounjaro. Compounded versions are not evaluated by the FDA for safety, purity, or efficacy. The FDA has warned consumers about this repeatedly, including in 2024 guidance on compounded GLP-1 products. "Cost-effective" does not mean equivalent.
- Postpartum metabolic recovery is its own process. Weight loss in the first few months after birth involves hormonal shifts, fluid changes, and, if breastfeeding, additional caloric demands. Attributing all change to tirzepatide this early is not reliable signal.
- The arm injection claim is not supported by tirzepatide prescribing data. Rotate sites as directed. Do not optimize based on TikTok tips.
- If you are postpartum and interested in any GLP-1 medication, that conversation needs to happen with an OB-GYN or a physician who knows your full postpartum and lactation status, not just a telehealth intake form.
