tirzepatide use during pregnancy vs. Semaglutide: What You Should Know BirthEzy

What the evidence supports: Injectable semaglutide was undetectable in breast milk from eight nursing mothers at doses up to 1 mg weekly Injectable tirzepatide was undetectable in approximately 96 percent of milk samples from 11 nursing mothers at 5 mg doses Both medications have molecular weights (4,114 and 4,813 Daltons) that make significant milk transfer biologically unlikely Any trace amounts in milk would have negligible oral bioavailability in the infant No adverse infant effects were observed in any of the lactation studies LactMed states tirzepatide is not a reason to discontinue breastfeeding What the evidence does not support: Use of oral semaglutide (Rybelsus) during breastfeeding due to the absorption enhancer SNAC Use of any GLP-1 agonist without physician supervision during lactation Aggressive weight loss goals (more than 1 to 1.5 pounds per week) while breastfeeding Assumption that compounded formulations carry the same safety profile as pharmaceutical-grade products without specific data What remains unknown: Safety at higher therapeutic doses (semaglutide above 1 mg, tirzepatide above 5 mg) Long-term infant outcomes from maternal GLP-1 exposure during breastfeeding Effects on breast milk composition and nutritional quality Safety of newer GLP-1 agonists like retatrutide The decision is ultimately yours and your physician's

The risk of lean mass loss during rapid weight reduction on tirzepatide is a particular concern for autoimmune patients who may already have muscle wasting from disease activity, corticosteroid use, or reduced physical activity during flares

Mounjaro and Zepbound pre-filled pens Brand-name tirzepatide from Eli Lilly comes in pre-filled, single-dose injector pens

Regular follow-up allows your provider to adjust your plan and support long-term results safely

Common concentrations for compounded tirzepatide include: 5 mg/mL - Lower concentration, requires larger injection volumes 10 mg/mL - Standard concentration, most commonly dispensed 20 mg/mL - Higher concentration, smaller injection volumes 30 mg/mL - High concentration, very small volumes per dose 60 mg/mL - Ultra-concentrated, available from select pharmacies The concentration determines how much liquid you need to draw up

Biohackers often report stacking Cagrilintide with smaller doses of GLP-1 peptides to smooth out the intense appetite suppression and nausea that comes with semaglutide or Tirzepatide
