Amped RTD Earthquake Grape
MET-Rx
Overview
MET-Rx Amped RTD Earthquake Grape is a pre/intra-workout supplement attempting to combine several popular ingredients for energy, pump, and muscle support. While it contains research-backed ingredients like Caffeine at an effective dose (200mg), and a good amount of Glycerin (10g) for hydration and potential pump, the efficacy of ingredients within the 'NOS Blend' and 'Neuro-Energy Blend' is severely hampered by proprietary blends. The 3g 'NOS Blend' contains L-Arginine, but without specific amounts, its effectiveness for nitric oxide production cannot be reliably assessed as effective doses often start higher for L-Arginine. Similarly, the 2.3g 'Neuro-Energy Blend' features ingredients like Taurine, L-Tyrosine, Yohimbine HCl, White Willow Extract, and Vinpocetine, but their individual dosages are unknown, making it difficult to determine if they reach clinically effective levels, particularly for ingredients like Yohimbine HCl which has a narrow therapeutic window. The BCAA 'Nitro Blend' at 1.25g is underdosed for optimal muscle protein synthesis or recovery benefit.
The Good
Provides a convenient ready-to-drink format for immediate consumption.
Contains a solid dose of Caffeine (200mg) for energy and focus.
Includes 10g of Glycerin which can aid hydration and muscle pump.
The Bad
Extensive use of proprietary blends (NOS Blend, Neuro-Energy Blend, Nitro Blend) hides individual ingredient dosages, preventing full efficacy and safety assessment.
Key ingredients like L-Arginine and BCAAs are likely underdosed for optimal benefits based on typical research-backed amounts.
Presence of Yohimbine HCl in an undisclosed quantity creates significant safety concerns due to stimulant interactions and potential side effects.
