20mg / 50 tablets per box



Tadalafil is a phosphodiesterase type-5 (PDE5) inhibitor in the same family as sildenafil (Viagra) and vardenafil (Levitra). Its standout characteristic is a very long elimination half-life of approximately 17.5 hours, compared to about 4 hours for sildenafil — a single dose can remain clinically active for over 36 hours, which is where the "weekend pill" nickname comes from.



Mechanistically, Tadalafil inhibits the breakdown of cyclic GMP in vascular smooth muscle, supporting blood flow in response to natural stimulation. It is approved by regulators for erectile dysfunction, benign prostatic hyperplasia, and pulmonary arterial hypertension. Common doses are 5 to 20mg taken either on demand or daily at lower strength.



Tadalafil is included in performance-oriented catalogs because libido, erectile function, and vascular response can be affected during anabolic cycles — particularly with compounds that suppress natural testosterone or shift estrogen balance. It is a support tool, not an anabolic, and pairs cleanly with cycle protocols.
