Sildenafil Citrate, widely known by its pharmaceutical brand name Viagra, is a phosphodiesterase type 5 (PDE5) inhibitor with one of the most extensively documented clinical histories of any pharmaceutical compound. F40 Biotech’s formulation delivers 50mg per tablet in a 50 count format, the standard recommended starting dose referenced in clinical prescribing guidelines, sitting between CSD’s chewable and effervescent 100mg presentations and CSD’s 200mg listing.
Clinical prescribing guidelines for Sildenafil typically recommend starting at 50mg, with titration up to the 100mg maximum only if the 50mg dose does not produce an adequate response, and reduction to 25mg if side effects are significant at 50mg. This makes the 50mg tablet the clinically appropriate starting point for most research applications rather than the 100mg dose, which is frequently assumed to be standard. Starting at the lower dose allows researchers to establish individual response and tolerability before considering dose escalation, consistent with the standard “start low” approach referenced across PDE5 inhibitor prescribing literature.
Sildenafil’s PDE5 inhibition mechanism remains consistent across all dose presentations, prolonging the cyclic GMP signal triggered by nitric oxide release during sexual stimulation, enhancing the natural erectile response rather than producing an effect independent of stimulation. CSD’s Sildenafil range now spans 50mg, 100mg (chewable and effervescent), and 200mg presentations, covering the full clinically referenced dose range from starting dose through to doses exceeding the established maximum.
F40 Biotech formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range.

Sildenafil should not be combined with nitrate medications, as this combination can cause a dangerous and potentially fatal drop in blood pressure. Consult a healthcare provider before use, particularly if you have cardiovascular conditions or take other medications.
Store in a cool, dry place away from direct light and heat.
