Evidence-based guides on performance optimization, hormone therapy, and peptide protocols — written to help you compare before you commit.
Peptide Education
23 min
Peptide therapy is one of the fastest-growing areas of men's health — and one of the most confusing. This guide covers every key question a beginner should answer before their first clinic consultation.
Peptide Guides

Ipamorelin and CJC-1295 work through completely different mechanisms — yet they're almost always prescribed together. This guide explains why, what each one actually does, and when it makes sense to use the combination vs each peptide alone.
Mental Health & TRT
17 min
Low testosterone and depression overlap in ways most men — and many clinicians — underestimate. Testosterone directly modulates serotonin, dopamine, and HPA axis function. When T is low, depressive symptoms often follow. When T is restored, mood frequently improves. Here is the full clinical picture, including what large trials actually show.
Peptide Therapy
17 min
BPC-157 is the recovery peptide most people associate with joints and tendons — but it was originally studied for gut healing. This guide separates what the research actually shows from gut-health marketing hype, and explains what to ask a clinic before pursuing it.
GLP-1 for Men
21 min
Both tirzepatide and semaglutide can suppress testosterone — but the magnitude, mechanism, and reversibility differ. This guide covers what men on TRT or considering hormone therapy actually need to know before choosing a GLP-1 protocol.
TRT Basics
28 min
Testosterone declines 1–2% per year after 30. But decline alone does not equal hypogonadism — symptoms plus lab confirmation are required before TRT is the right call. Here is what the evidence actually shows for men over 40.
Peptide Guides
22 min
Sermorelin stimulates your pituitary to produce its own growth hormone. HGH injections deliver synthetic somatropin directly. The mechanisms, costs, and risks are fundamentally different — and for most men, sermorelin is the more practical and accessible option.
TRT Comparisons
19 min
Most TRT clinic rankings are written by the clinics. This guide gives you the neutral evaluation rubric — five quality variables, seven red flags, and a decision framework — so you can identify the right provider before you commit to one.
Peptides & Longevity
23 min
NAD+ is being prescribed alongside TRT at an increasing number of specialist men's health clinics. But what does the research actually say about combining them? Here is what we know about NAD+ deficiency, testosterone metabolism, and whether IV or oral NAD+ supplementation meaningfully improves outcomes on TRT.
Peptide Costs
19 min
Sermorelin programs range from $150 to $600+ per month depending on the clinic model and whether labs and monitoring are included. Here is the honest cost breakdown so you can compare options without getting misled by headline pricing.
TRT Education

The short answer: no, not meaningfully. OTC testosterone boosters are classified as dietary supplements — a category the FDA regulates far less strictly than prescription drugs. Here is what that actually means for safety, labeling accuracy, and whether these products can do what they claim.
Peptide Therapy
22 min
Most peptide users quit too early or read hype timelines too optimistic to be useful. Here is when each major peptide actually starts working — with mechanistic context so you know whether to wait, adjust, or stop.
TRT Safety
25 min
Low testosterone is a meaningful driver of bone loss in men — and the T-Trials and TRAVERSE both show TRT can reverse it. But the biggest bone health risk on TRT is not hypogonadism. It is anastrozole overuse crashing estradiol.
TRT Protocol
24 min
Most men starting TRT focus on the prescription. The smarter move is understanding the blood work — what to test, when to test it, and which numbers actually require action. This is the complete monitoring guide.
Testosterone Optimization
23 min
Most advice on raising testosterone naturally oversells what lifestyle changes can do. This guide ranks every major natural strategy by effect size, gives realistic expectations, and explains when natural approaches hit their ceiling.
TRT Side Effects
23 min
Brain fog and concentration problems are among the most commonly reported low-T symptoms — but the relationship between testosterone and cognitive function is more nuanced than most TRT content acknowledges. Here is what the research actually shows, and how to tell whether your brain fog is hormone-related.
Sexual Health
23 min
PT-141 works through a completely different pathway than testosterone or Viagra — it activates melanocortin receptors in the brain to directly stimulate sexual motivation. Here is what the clinical evidence actually shows for men, and what using it looks like in practice.
TRT Safety
19 min
For 40 years, the medical community assumed testosterone fed prostate cancer — based on thin, outdated evidence. The TRAVERSE trial and the Saturation Model have largely overturned that view. Here is what the research actually shows about TRT and prostate health in 2026.
TRT Safety
21 min
For years, conflicting data made cardiovascular risk the most debated topic in TRT. The 2023 TRAVERSE trial — 5,246 men, 33-month median follow-up — settled the primary question: TRT in hypogonadal men does not significantly increase major cardiovascular events. Here is what the evidence actually shows.
TRT
20 min
TRT reliably improves libido — but erectile dysfunction is more complicated. Here is what the research actually shows about testosterone and ED, when TRT is enough on its own, and when you need a PDE5 inhibitor or PT-141 in combination.
Peptide Safety
17 min
Most peptide side effect content is either too dismissive ('side effects are rare and mild') or too alarming. This guide covers what actually tends to happen across common peptide categories, when symptoms are expected and manageable, and when they are a signal that something is wrong — with your protocol, your provider, or your peptide source.
Peptide Costs
16 min
TB-500 pricing ranges from $30 to $700+ per month depending on how you source it and whether you include clinical oversight. Here is the honest cost breakdown by path so you can compare options without getting misled by headline pricing.
TRT Deep Dives
18 min
TRT reliably adds lean body mass in hypogonadal men — but the amount, the timeline, and whether it translates to real-world strength depend on things most articles skip. Here is what the research actually shows.
TRT Deep Dives
21 min
Low libido is one of the top three reasons men seek TRT — and one of the most responsive symptoms to treatment. But the mechanism, the timeline, and the important distinction between desire and erection quality are almost never explained well. Here is what the research actually shows.
