Serena Williams' comeback is huge for peptide bros

• Serena Williams is returning to tennis at age 44, with her first pro match the week of June 8.
• Williams has been open about using a GLP-1 to lose weight, saying it helps her move better.
• Her comeback is great news for people who believe in peptides for longevity and performance.

Davidson said he has lost over 30 pounds in three months. He feels like the GLP-1 has helped him maintain more strength than he usually does in the slim-down phase before a big event.

“I really haven’t gotten any weaker,” Davidson said.

Afshar said the “super optimizers” like Davidson are rarities in his practice, but he knows at least a few people who fit into the category.

Doctors vehemently recommend against doing this without medical supervision.

Williams is not part of this performance enhancement and fitness-optimization-through-peptides band of GLP-1 users; she is promoting these drugs for FDA-approved uses, including blood sugar control and clinical weight loss.

Still, her big comeback to the court next week is great news for the pro-peptide guys, who are keen to show that peptides are much more than drugs to treat chronic diseases like obesity and type 2 diabetes.
