PDE5 enzyme regulates blood flow causing vasoconstriction. This hinders post-exercise recovery. TESTOSURGE® inhibits PDE5 activity and promotes vasodilation, which increases blood flow to the muscles, aiding in recovery. Testosurge exhibits a 90% inhibition rate at 1000 µg/mL.

Phosphodiesterase type 5 (PDE5) inhibitors are a class of drugs that are primarily used to treat erectile dysfunction (ED) and, in some cases, pulmonary arterial hypertension (PAH). They work by blocking the enzyme phosphodiesterase type 5 (PDE5), which increases the levels of cyclic guanosine monophosphate (cGMP). This, in turn, leads to relaxation of smooth muscle cells, allowing for increased blood flow to certain areas of the body, such as the penis.

The most commonly known PDE5 inhibitors include:

Sildenafil: Marketed under various brand names, with Viagra being the most well-known for treating erectile dysfunction and Revatio for treating PAH.

Tadalafil: Known by the brand name Cialis among others, it is used for treating erectile dysfunction and also for the treatment of PAH and benign prostatic hyperplasia (BPH).

Vardenafil: Sold under the brand name Levitra, it is used for treating erectile dysfunction.

Avanafil: Marketed as Stendra in the US and Spedra in the EU, it is a newer drug used for treating erectile dysfunction.

These medications are generally well-tolerated but can have side effects and interactions with other medications, so they should be taken under the guidance of a healthcare provider.

Testosurge is an all-natural supplement.
