FDA career scientists say there's insufficient evidence for all 7 peptides under review, directly contradicting RFK Jr.'s push to expand access. Here's what the briefing documents actually say.

The Hidden Impurity in Compounded Tirzepatide: What Lilly's Lab Found in Your B12 Combo
Eli Lilly's analytical labs discovered a novel chemical impurity in compounded tirzepatide-B12 products—a compound formed by a reaction between the two ingredients that nobody has tested for safety.

VK2735: The Oral Weight Loss Pill That Lost 26 Pounds in 13 Weeks
Viking Therapeutics just showed that their oral dual GLP-1/GIP agonist VK2735 produced 12.2% weight loss in 13 weeks — no injections required. Here's what the Phase 2 data means for the future of weight loss pills.

Why BPC-157 Still Hasn't Reached Clinical Trials After 30 Years of Research
BPC-157 has thousands of preclinical studies showing tissue-healing effects across nearly every organ system. So why does it still have zero completed clinical trials? A May 2026 review finally explains the gap.

Do GLP-1 Drugs Sabotage Fat Grafts? What the Latest Surgery Data Actually Shows
New studies show semaglutide users face a 45% complication rate in cosmetic surgery. Here's why GLP-1 drugs interfere with fat graft biology and what surgeons are doing about it.

Thymosin Alpha-1 in Cancer Immunotherapy: New Mechanism Restores Immunity After Chemo
Three 2026 studies reveal how thymosin alpha-1 restores antitumor immunity after chemotherapy, reverses T-cell exhaustion, and synergizes with checkpoint inhibitors.

Semaglutide Cuts Cardiovascular Events by 25% in Rheumatoid Arthritis Patients: New Study
A June 2026 study found semaglutide reduced major cardiovascular events by 25% and heart failure by 31% in obese adults with type 2 diabetes and rheumatoid arthritis, with a surprising bonus: fewer patients needed stronger RA medications.
