MCT vs. Seed Oil in Injectable Testosterone

If you wouldn’t eat it, why are you injecting it? When it comes to testosterone replacement therapy (TRT), most people focus on dose, frequency, or lab markers. But there’s one overlooked factor that can dramatically impact how you feel on treatment: the carrier oil in your injection. At Marek Health, we prioritize the effectiveness of your therapy as well as your comfort, tolerance, and long-term outcomes. That’s why we prefer MCT oil-based testosterone formulations as part of our precision TRT protocols. Here’s what you need to know about the differences between MCT oil and seed oils in injectable testosterone—and why the carrier matters more than you think.

Can Omega-3 Supplements Help Your Brain Grow New Cells?

What if taking a simple supplement could literally help your brain regenerate itself? It might sound like science fiction—but exciting new research confirms it's very real. Omega-3 fatty acid have long been known to support heart health. Now, compelling evidence shows omega-3 supplements also stimulate your brain to create new neurons, potentially improving memory, mood, and overall mental clarity.

Gut Health: The Unsung Hero of Longevity and Vitality

Your gut isn’t just where food is broken down—it’s a command center. In fact, over 70% of your immune system resides in the gut-associated lymphoid tissue (GALT), embedded throughout the intestines to act as a front-line defense against pathogens and toxins. The gut is also home to the enteric nervous system, often called the “second brain,” which communicates constantly with your central nervous system and influences everything from mood to cognition via the gut-brain axis. A healthy gut can mean better energy, clearer skin, sharper cognition, stronger immunity, and even a reduced risk of chronic disease. A dysfunctional gut, on the other hand, can quietly sabotage progress in all of these areas.

Outsmart Your Genetics: How to leverage peptides to overcome biological barriers to weight loss

With obesity affecting over 1 billion individuals, it’s becoming clear that it’s not just about willpower or habits – your genes play a major role in your weight. Large genome-wide association studies (GWAS) have identified hundreds of genetic sites that influence body weight and obesity risk. Each of us inherits a unique mix of these DNA variants, some of which can subtly (or not so subtly) tip the scales. For example, in 2007 scientists discovered the FTO gene was linked to obesity. Mice engineered with extra copies of FTO become obese, while mice lacking FTO stay lean even on a high-fat diet. This gene’s effect is so powerful that a common variant of FTO carried by about 1 in 6 people makes them 70% more likely to become obese.

Can High-Dose Vitamin D Help Shift Calories from Fat to Muscle?

When most people think of vitamin D, they think of bone health, immune support, or soaking up some sunshine. But groundbreaking new research is pointing to another compelling benefit: the potential for optimized vitamin D intake to influence how your body stores excess calories. A recent preclinical study revealed that high levels of dietary vitamin D may help direct surplus calories toward muscle growth and away from fat storage. This discovery could significantly shift our understanding of metabolism, energy allocation, and even body composition management—especially in contexts like obesity, aging, and sarcopenia (muscle loss).

Aging is a Disease- Here’s How to Fight Back

What if everything you’ve been told about aging is wrong? Aging is the biggest risk factor for chronic diseases like diabetes, dementia, heart failure, osteoporosis, and liver disease—yet we’ve been led to believe it’s an unstoppable decline we have to accept. Recent research indicates that aging is a highly modifiable process driven by cellular senescence, stem cell exhaustion, altered intracellular communication, genomic instability, mitochondrial dysfunction, and telomere shortening. Here are four actionable steps our clinical director, Memo Canli, is taking to “fight back” against aging.

Marek Hair Loss Topical

Hair loss sufferers know all too well that androgenetic alopecia (AGA) – the most common form of hair loss – is a complex condition with multiple factors at play. The gradual thinning and receding of hair (in both men and women) stems from more than just genetics; it involves hormonal influences, inflammation, oxidative stress, and progressive miniaturization of hair follicles. Scientists have spent decades unraveling these mechanisms. Notably, hair biologists like Dr. Ralf Paus have illuminated how hormones like DHT (dihydrotestosterone), immune factors, and even oxidative damage conspire to shrink follicles over time. The exciting news is that cutting-edge research has paved the way for Marek Health's new topical hair formula containing 1% Dutasteride, 8% Minoxidil, 0.01% Tretinoin, 2% Caffeine, 1% Melatonin, 2% Azelaic Acid, 0.1% Sirolimus (Rapamycin), and 0.0003% Liothyronine (T3).

The Health Markers Most Women Are Missing

If you've ever been told, "Your labs are normal" but still struggle with fatigue, brain fog, mood swings, or stubborn weight gain, you are not alone. Too many women are dismissed, told their symptoms are "just part of getting older," or left searching for answers on their own. But the truth? Your body is telling you something—and you deserve to be heard. For women 30+ who prioritize fitness and optimal health, there are key health markers that often go overlooked in standard medical checkups. These markers influence everything from metabolism and performance to mood and recovery. If you're serious about feeling and performing at your best, here's what you need to know.

Testosterone Replacement Therapy: The Overlooked Benefits

Testosterone replacement therapy (TRT) is widely recognized for its role in muscle growth and strength, but emerging research reveals it offers far more than just physical benefits. Studies now show that TRT can enhance cognitive function, confidence, decision-making, cardiovascular health, and overall well-being—transforming how men think, feel, and perform in daily life. This article delves into the latest peer-reviewed medical research, highlighting how TRT positively impacts memory, attention, mood, financial decision-making, heart health, and recovery.

What Your Sex Life Says About Your Heart Health

Cardiovascular disease (CVD) is one of the leading causes of death worldwide—but did you know your sexual health could be an early warning sign? The Massachusetts Male Aging Study (MMAS) revealed a significant connection between erectile dysfunction (ED), sexual activity, and cardiovascular risk. Men with ED had a higher risk of heart disease, and those who had sex less than once a month were at a 45% greater risk of developing cardiovascular issues. So what does this mean for you? Your heart health and sexual function are deeply connected. At Marek Health, we use advanced diagnostics and a proactive approach to detect early signs of cardiovascular risk and create personalized plans to mitigate it—before it becomes a serious issue.
