Stark Tribulus Liquid Extract 50 ml (tribulus extract)

Stark Tribulus Liquid Extract 50 ml — sublingual tribulus extract for tone and libido

Stark Tribulus Liquid Extract is a liquid herbal extract of tribulus (Tribulus terrestris) in the form of a sublingual spray.

Tribulus contains steroidal saponins of the furostanol type; the product description mentions protodioscin as the key component.

The sublingual spray format is convenient for dosing throughout the day without capsules or powders.

Briefly about the product:

• Form: sublingual spray.
• Volume: 50 ml.
• Ingredients: tribulus herb and fruit; water; propylene glycol.
• Recommended dosage: 1–3 injections 3 times a day.
• Course approach: after 1–3 months of use, take a break for 2–4 weeks.

How it works:

• Saponins: Bioactive compounds in Tribulus may affect signaling processes associated with adaptation to stress.
• Protodioscin: The product description states that protodioscin is extensively biotransformed and relatively rapidly degraded in blood plasma.
• Neurosteroids: The clinical literature discusses the possible relationship of tribulus saponins to DHEA levels as one mechanism that may be relevant to sexual function.
