Frequently Asked Questions
What is better for weight loss: semaglutide or tirzepatide?
Clinical trial data suggests tirzepatide produces greater average weight loss (up to 22.5% in SURMOUNT-1) compared to semaglutide (up to 16.9% in STEP 1). Tirzepatide is a dual GIP/GLP-1 agonist while semaglutide targets GLP-1 only. Individual responses vary. See our detailed semaglutide vs tirzepatide comparison.
How do you compare peptides fairly?
We compare peptides across standardized dimensions: mechanism of action, clinical evidence strength, efficacy data, dosing protocols, side effect profiles, cost, FDA status, and real-world community reports. We cite specific studies with PubMed IDs so you can verify every claim.
Is BPC-157 or TB-500 better for injuries?
They work differently. BPC-157 promotes local angiogenesis and growth factor expression — better for tendon, ligament, and gut healing. TB-500 acts systemically on inflammation and cell migration — often preferred for muscle injuries and broader inflammation. Many protocols stack both for synergistic effects.
What is the most effective GLP-1 peptide?
By weight loss percentage in clinical trials, retatrutide (triple agonist) showed the highest efficacy at 24.2% in Phase 2. Among approved medications, tirzepatide leads at 22.5% (SURMOUNT-1). Semaglutide 2.4 mg showed 16.9% (STEP 1). Effectiveness varies by individual.
Should I compare brand-name or generic peptides?
Compare by active compound, not brand name. Ozempic and Wegovy are both semaglutide at different doses. Mounjaro and Zepbound are both tirzepatide. Compounded versions contain the same active peptide but may differ in purity, concentration, and manufacturing quality.
