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. This formulation delivers 200mg per tablet in a 10 count format, double the standard maximum recommended dose of 100mg referenced in clinical prescribing guidelines for Sildenafil.

It’s important to understand the dose response relationship for Sildenafil before considering a 200mg tablet. Clinical trial data establishing Sildenafil’s efficacy and safety profile was conducted up to the 100mg dose. Doses above 100mg have not demonstrated meaningfully improved efficacy over the 100mg dose in available clinical literature, while the rate of dose dependent side effects, including headache, flushing, visual disturbances, and hypotension, increases with higher doses. This means a 200mg tablet does not represent “double the effect” of a 100mg tablet. The additional 100mg primarily increases side effect risk without a corresponding clinical benefit.

For this reason, the standard recommendation in clinical and pharmacological literature is to use the lowest effective dose, with 100mg as the established maximum. If considering this product, splitting the tablet in half to achieve a 100mg dose, or sourcing CSD’s standard 100mg presentations directly, is the more clinically aligned approach.

Sildenafil’s PDE5 inhibition mechanism operates by 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.

Every batch of CSD’s Sildenafil is third party lab tested for concentration accuracy and purity before being made available, with COA documentation available on request. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.

Sildenafil should not be combined with nitrate medications (commonly prescribed for chest pain/angina), as this combination can cause a dangerous and potentially fatal drop in blood pressure. Higher doses carry an increased risk of side effects including headache, flushing, visual changes, and hypotension. 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.
