BPC-157, TB-500, and four other peptides, short chains of amino acids, sold through online gray markets may soon be easier to get with a prescription if FDA follows a late-July 2026 advisory panel. The biology behind them is real enough to justify research, and moving them into pharmacies could pull some use away from the least regulated corners of the internet. But a panel vote is not FDA approval. These peptides still lack the human trials that would tell you what they help, at what dose, by which route, and with what short- and long-term risks.

If you're an older adult, lifting weights, or trying to lose fat without losing muscle, the old 0.8 grams per kilogram of body weight per day (g/kg/day) Recommended Dietary Allowance (RDA) is aimed lower than your goal. The better-supported range for those situations is about 1.2 to 1.6 g/kg/day, with older-adult guidance often starting around 1.0 to 1.2 g/kg/day. In resistance-training studies, meaning studies of structured strength exercise, the added muscle payoff flattens around 1.6 g/kg/day, and the popular push toward roughly 2.2 g/kg/day isn't backed by strong long-term data for ordinary adults. One detail carries the rest: protein works best alongside strength training, not instead of it.

You have more influence over dementia risk than the word prevention usually implies, but less certainty than supplement ads suggest. The best-supported levers are regular exercise, a Mediterranean-style diet or MIND pattern, which blends Mediterranean eating with a blood-pressure-focused diet, treating high blood pressure and other vascular risks, and staying mentally and socially engaged. In older adults at elevated risk, structured programs that combine these habits improve cognitive test scores in randomized trials. What none has yet proven is that any lifestyle plan prevents Alzheimer's disease itself. That gap is honest, and it still leaves a concrete plan worth acting on, especially if your own risk runs high.
SleepJul 31, 2026
Tiredness that survives a full night's sleep has real, findable causes: sleep apnea, iron deficiency before anemia sets in, an overtly underactive thyroid, depression or anxiety, inflammatory disease, diabetes, cancer-related fatigue, or a post-infection syndrome like Long COVID. Some causes are treatable; others need symptom-focused management once recognized. The productive move is to match your symptom pattern to targeted evaluation, including labs or sleep testing when the clues fit, not to order every blood marker you can think of.
SleepJul 31, 2026
Protecting regular, adequate sleep is one of the more defensible longevity habits, though not for the reason you usually hear. Short sleep can quickly worsen systems that drive long-term health, especially how your body handles glucose and insulin. The popular claim that every night under seven hours subtracts a measurable slice of your lifespan is a different thing, and it is not settled. Sleep is worth guarding for what it demonstrably does to metabolism and physical resilience, not because a cohort study assigned it a number.

If your actual choice is a regular soda versus a diet one, the diet version is usually the better choice for weight and blood sugar exposure: randomized trials show a small weight benefit and much lower immediate blood sugar and insulin exposure than sugar. That is a substitution argument, not a health claim. Non-sugar sweeteners are not proven to be better than water or unsweetened drinks as a long-term health strategy, and the people who use them most heavily carry higher long-term rates of diabetes and heart disease, though those studies cannot prove the sweeteners caused those outcomes.
Heart HealthJul 30, 2026
If your LDL cholesterol climbs above 200 mg/dL after you start a ketogenic diet, being lean, active, high-HDL, and low-triglyceride does not prove your arteries are protected. The direct imaging evidence is thin: one coronary CT angiography study of lean keto dieters found no greater plaque at one scan after several years on the diet, but the follow-up paper meant to track whether plaque worsened was retracted. Against that sits far stronger human evidence that apolipoprotein B (apoB), a protein found one-per-particle on many cholesterol transport particles that can enter artery walls, marks particles that causally drive plaque buildup over years of exposure. The honest answer is not to panic, but not to treat this pattern as a proven safe exception either.
LongevityJul 30, 2026
In 40 sedentary adults aged 65 to 85, adding 6 mg of weekly sirolimus, the prescription drug also known as rapamycin, to a 13-week home exercise program did not improve function over exercise alone. Both groups got better, but the drug group gained about two fewer chair-stands than placebo in the main analysis, and the per-protocol sensitivity analysis, limited to adherent participants, favored placebo more strongly. This one small trial does not settle rapamycin's broader longevity question, but it does not support taking it to get more out of workouts.

If you are trying to protect your fertility, cutting back on ultra-processed foods, industrial formulations such as packaged snacks, sweetened cereals, chips, and sugary drinks, is a reasonable move, but as part of a better overall diet, not because processing has been proven to poison sperm. A 2025 feeding trial tried to separate processing from overeating and found short-term weight and blood-fat changes over three weeks, while the sperm and hormone signals stayed modest and statistically fragile.
CancerJul 30, 2026
For most average-risk women, screening starts with mammography at 40, not a reflexive stack of extra scans. What is worth personalizing is intensity: whether your risk justifies annual rather than every-other-year testing, 3D mammography, or supplemental magnetic resonance imaging (MRI). Women with a calculated lifetime risk of at least 20%, an inherited pathogenic variant in a breast cancer risk gene such as BRCA1 or BRCA2, strong family-history patterns, or high-dose chest radiation before age 30 may need earlier or MRI-based screening; extremely dense breasts can justify a separate MRI discussion after a normal mammogram. The move that matters is a formal risk assessment, not an automatic extra test.

Every physical action, from a single muscle twitch to a maximal sprint, depends on adenosine triphosphate (ATP), the body’s immediate energy currency. The challenge is that muscles only store a tiny amount of ATP, enough for about two seconds of high-intensity activity.
When ATP is depleted, the body relies on a rapid buffering system called the phosphagen system. This is where creatine plays a key role. Inside cells, creatine stores phosphate in the form of phosphocreatine, which acts like a rechargeable energy battery. When energy levels drop, phosphocreatine releases its phosphate to quickly rebuild ATP. This rapid energy recycling is what makes creatine so effective for improving short-term power, speed, and recovery.
The key to optimizing this system lies in saturation. When creatine stores are full, performance and recovery both reach their physiological potential. This is the goal of the loading phase.
CreatineJul 24, 2026
Creatine gummies taste good, so it is no surprise that they are an attractive option if you are thinking about supplementation. But there is a price to pay for that taste, and unfortunately that price is effectiveness.

If the first couple of 2.5 mg doses of Zepbound hit you hard with nausea, vomiting, or diarrhea, you have two obvious options: quit, or grit your teeth. There is a third. The multi-dose KwikPen has a dial that clicks as you turn it, and each click delivers a small, predictable volume, so you can take a fraction of the 2.5 mg starting dose and work up gradually instead. Here is how the click system works, the math behind it, and what else helps with the side effects.
GeneticsJul 24, 2026
The dream of reversing aging once belonged to myth, miracle diets, and Silicon Valley optimism. But for the first time, scientists have a molecular tool that could reprogram the biology of aging itself. That tool is CRISPR—the gene-editing system that can cut, replace, or silence DNA with extraordinary precision. Its discovery transformed molecular biology in less than a decade, and its medical ambitions are even greater: to treat disease by rewriting the genetic code.
The question is no longer whether CRISPR can target diseases of aging, but when it will do so safely in human patients. The road to mainstream medicine runs through a gauntlet of safety testing, ethical scrutiny, and biological complexity.
CholesterolJul 24, 2026
Lipfendra (enlicitide) is the first once-daily oral PCSK9 inhibitor, a pill that lowered LDL cholesterol by about 56 percent beyond a placebo pill in a roughly 2,900-person trial. Its reported list price is about $315 a month, but it has not yet been shown to prevent heart attacks or strokes.

A lower dose of a statin paired with ezetimibe can deliver the same cardiovascular protection as cranking the statin dose to maximum, while causing fewer muscle complaints, less diabetes risk, and better long-term adherence. That's the core finding from large randomized trials and meta-analyses comparing these two strategies head to head.
If you've been told you need a statin but worry about tolerability, or if you're already on a high dose and struggling with side effects, this combination approach is worth understanding. The evidence is strong enough that it's reshaping how clinicians think about lipid-lowering therapy, especially for older adults and people prone to statin-related problems.
SupplementsJun 4, 2026
Creatine has long been recognized as one of the most effective and well-researched supplements for improving both muscle performance and cognitive function. Still, the first question most people ask isn’t about strength or focus, but appearance. Will creatine make me gain weight, and if it does, will that weight be the kind I actually want?
Colon CancerJun 4, 2026
Colorectal cancer stands as one of the deadliest cancers worldwide, yet it is also one of the most preventable. For women, the story of prevention often begins with a single procedure: the colonoscopy. More than just a diagnostic tool, the evidence from large-scale studies, clinical trials, and decades of clinical practice strongly suggests that the colonoscopy is indispensable for early detection in women.
Vitamin B12Jun 4, 2026
Vitamin B12 is an essential nutrient responsible for maintaining healthy nerve function, producing red blood cells, and supporting DNA synthesis. When the body lacks sufficient B12, a variety of symptoms can appear, including fatigue, cognitive changes, anemia, and neurological issues. These symptoms are typically attributed to nutritional causes or absorption problems. However, research has increasingly identified links between vitamin B12 deficiency and certain cancers, raising important questions about whether such a deficiency could sometimes be a sign of an undiagnosed malignancy.
Skin HealthJun 4, 2026
The nose is the single most common site on the face for non-melanoma skin cancer. It protrudes, it catches sun year-round, and its complex anatomy makes both removal and repair a challenge. But the research is clear on what determines whether nasal skin cancer comes back: clean surgical margins. When surgeons achieve clear margins, recurrence sits around 6%. With positive (incomplete) margins, it climbs to roughly 24%.
That fourfold gap makes the surgical approach one of the most consequential decisions in treatment, sometimes more so than the specific type of cancer itself.
