PharmaTirzepatide versus semaglutide: the head-to-head, and what an observational study adds
SURMOUNT-5 randomised 751 adults with obesity and without type 2 diabetes to maximum tolerated dose tirzepatide or semaglutide for 72 weeks. Least-squares mean weight change was -20.2% (95% CI -21.4 to -19.1) with tirzepatide and -13.7% (95% CI -14.9 to -12.6) with semaglutide, P<0.001; waist circumference -18.4 cm against -13.0 cm. Open-label, sponsored by Eli Lilly, with two published correspondence items.

One trial in healthy adults, one clear result: a week of raised GH and IGF-I from a single injection. The catch is chemical. The tested molecule carried an albumin-binding add-on, and a preparation without it is a different pharmacokinetic story.

After a heart attack, mammalian heart muscle barely regenerates. A line of preclinical work asks whether a thymosin beta-4 peptide can change that equation in animals. Here is what the reviews report, and where the line stops.
