Testosterone without a prescription and online sellers: the real risks, and why no website selling it in Spain is legal

Testosterona baja (hipogonadismo): síntomas reales y cuándo preocuparse

Low testosterone (hypogonadism): the symptoms that actually matter and when to worry

Low testosterone has become a catch-all explanation for tiredness or low mood, but genuine hypogonadism is something else: it requires specific symptoms plus a confirmed blood test, and it is less common than the marketing suggests.

Sildenafilo: qué es, cómo funciona y qué dice la evidencia

Sildenafil: what it is, how it works and what the evidence says

For almost three decades sildenafil has been the best-known drug for erectile dysfunction, and also one of the most misunderstood.

Diagnosis and tests

PSA y testosterona: qué se revisa antes de iniciar tratamiento hormonal

PSA and testosterone: what is checked before starting hormone treatment

Before starting testosterone, a PSA test is not the only thing that is checked. The guidelines call for hypogonadism to be confirmed with symptoms and appropriate blood tests, and for the prostate, haematocrit, fertility and other possible causes of the symptoms to be assessed.

Testosterone supplements: what the evidence says (and what's just hype)

Testosterone boosters, maca, tribulus, zinc, ashwagandha… the shelves are full of promises. We take a calm look at what the science actually supports, what is pure marketing and why it matters to tell a genuine deficiency apart from a passing trend.

Testosterone gel vs injection: what changes depending on the route of administration
