What's different vs. Specimen GFY V2? Halostachine, hordenine, and synephrine were dropped for Specimen GFY V3, as well as no more SantEnergy™ Nu Santa Herba, but everything else from V2 was brought forward. Highlights of the retained ingredients include a full 3.2g of beta-alanine, 1000mg Astrolyte™ electrolyte blend, 200mg of English Ivy, and the original Specimen paradigm of 400mg of caffeine against the backdrop of Glaxon's signature rauwolscine (alpha-yohimbine) + yohimbine combo (aka, Yo-Yo). GFY V3 adds a ton of blue chip premium compounds to offset the ingredients that weren't carried forward: 100mg of NeuroFactor® clinically shown to significantly increase levels a neuroprotein (BDNF) vital to learning, memory, and higher thinking; 250mg of RhodioPrime® 6X branded rhodiola, a market-leading 6% salidroside extract; 30mg of gamma-butyro-betaine ethyl ester chloride (GBB), a pro-compound that doubles that effectively doubles plasma carnitine levels; and 254mg of VasoDrive-AP® to improve arterial flexibility by potentiating the production of eNOS. So GFY V3 more than picks up the slack vs. what fell out of the formula.
