This formulation combines Sildenafil 65mg and Tadalafil 25mg in a single tablet, the lower concentration variant in CSD’s dual PDE5 inhibitor range alongside the Superman V2 130mg listing. As with Superman V2, both compounds act on the same PDE5 enzyme target through the same fundamental mechanism, meaning this is two inhibitors of the identical pathway rather than two independent or complementary mechanisms working together.
At 65mg Sildenafil and 25mg Tadalafil, this formulation sits below the standard maximum recommended dose for either compound individually (100mg Sildenafil, 20mg Tadalafil) on the Sildenafil side, but the Tadalafil component at 25mg already exceeds Tadalafil’s standard maximum of 20mg. This is a meaningfully different dose profile from the Superman V2 130mg variant, which delivers both components at or above their individual maximums. Superman 90mg represents a moderated version of the same dual inhibitor concept, though it still combines two PDE5 inhibitors acting on the same pathway simultaneously.
The same underlying consideration applies to combining any two PDE5 inhibitors regardless of the specific dose split; there is no established clinical evidence that combining Sildenafil and Tadalafil produces better outcomes than an adequate dose of either compound alone, since both compete for the same enzyme binding site rather than acting through separate mechanisms. The combined side effect burden, and the absolute nitrate interaction contraindication, apply to both compounds simultaneously regardless of dose.
Every batch of CSD’s Superman 90mg is third party lab tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD stocks two dual PDE5 inhibitor presentations: this 90mg and the higher concentration 130mg Superman V2 — for researchers specifically examining comparative dose response across combined PDE5 inhibitor formulations. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
This product combines two PDE5 inhibitors. While the total dose is lower than the Superman V2 130mg variant, this combination still carries elevated side effect risk compared to either compound alone, and must not be combined with nitrate medications under any circumstances. Strongly consult a healthcare provider before considering this product, particularly if you have any cardiovascular conditions, take other medications, or have not previously used either compound individually.
Store in a cool, dry place away from direct light and heat.
