What's new in feeling better and living longer. 5-minute read.
Good morning. Today: federal health officials cleared a path for pharmacies to make six popular peptides, a small study on testosterone, estrogen and spine density, and what your walking pace may say about longevity.
01 ยท PEPTIDES ยท REGULATION
HHS cleared pharmacies to compound six popular peptides
HHS said Oct. 28 it won't take action against state-licensed compounding pharmacies, federal facilities or licensed physicians that compound six peptides: BPC-157, TB-500, MOTS-c, epitalon, KPV and semax.
Why it matters: These peptides have largely been sold online as "research-use-only" products, often from overseas suppliers, and the policy offers a pharmacy route instead, NPR reported.
The details: Products must be made for a specific patient and contain only one of the peptides, with ingredients from FDA-registered manufacturers and serious side effects reported to the FDA, according to a summary by law firm Frier Levitt. Larger 503B outsourcing facilities aren't covered. The policy is temporary while the FDA works on rules, and its Federal Register notice is set for Oct. 30.
Yes, but: The peptides aren't FDA-approved, and AP reported most FDA scientific staff opposed the plan. "All peptide substances should go through the standard FDA approval process for new drugs," said Public Citizen's Dr. Robert Steinbrook. One pharmacy owner told NPR, "We won't be able to meet demand." Talk to your doctor.

02 ยท HORMONES ยท BONE HEALTH
Adding testosterone to estrogen was tied to denser spine bone
In 51 postmenopausal women, adding testosterone to estrogen therapy was tied to a significant rise in lumbar spine bone density, while estrogen alone held density steady, per a USC abstract at The Menopause Society's annual meeting.
Why it matters: Hormone therapy is often discussed for protecting bone after menopause, and research on testosterone's role in women's bone health has been sparse and contested, ScienceAlert noted.
The details: Women had DEXA scans at baseline, after at least a year of estrogen alone and after at least a year of estrogen plus testosterone, over an average of 4.1 years. Hip and femoral neck scores stayed stable in both periods. The researchers suggested testosterone may work with estrogen on the spongy inner (trabecular) bone of the spine.
Yes, but: The study is small, hasn't been peer reviewed and compared two treatment periods in the same women rather than separate groups. No numeric results, fracture outcomes or safety data were released. The Menopause Society's medical director, Dr. Stephanie Faubion, said more research is needed. Talk to your doctor.

Faster walkers had a lower risk of death over 12 years
In a UK study of 4,067 older adults followed for nearly 12 years, each standard-deviation increase in clinic walking speed was tied to a 23% lower risk of death.
Why it matters: Walking pace and step rate are simple measures, and the study compared a quick clinic test with what a wrist sensor recorded in daily life.
The details: Participants in the Whitehall II study averaged about 69 years old, and about one-third were women; 739 died during follow-up. A higher everyday step rate, measured by a wrist-worn accelerometer over nine days, was tied to a 17% to 18% lower risk. The two measures were only weakly related, and results were similar for women and men. Published Oct. 23 in JAMA Network Open.
Yes, but: It's observational, no absolute risks were reported, and combining the measures added little after full adjustment. "People who naturally walk faster may already have better underlying health," physical therapist Neha Sabharwal, who wasn't involved, told Healthline.
