l-carnitine fumarate is often overlooked, but a great performance increaser.actually people with chronic fatigue syndrome tend to react negatively to lclt and alcar but not lc-fumarate.
i think the most important supplements in regards to health and body composition are nutrient partitioners, aromatase inhibitors and antioxidants.
a simple regimen would be something like inhibit-e (great product for overall health too and thyroid), burn24 by omega sports, l-carnitine fumarate 3 grams preworkout and a lot of dark chocolate at least 80%cocoa. contains theobromine, many aminos, small amounts of various stimulants and epticatechin. one of the healthiest foods there is with an orac twice as high as wild blueberries and also posesses fat loss properties.
a great, healthy, cheap effective preworkout would be a cup of strong coffee, 2 grams dl-phenylalanine, 1 gram chocamine or 40-80grams bitter chocolade, 3 grams l-carnitine fumarate. if you wanna optimize this add 1 gram of agmatine, a good brand or if possible agmapure or even ergonox by myodyne and 200mg ubiquinol. take this 1.5 hours preworkout and have something with carbs in it 30 min. preworkout and intra, for example 16 oz. of chocolate milk. the agmatine will shuttle the carbs into the muscle, this will potentiate the pump more than just agmatine alone without carbs, the powergrape from the ergopure gives great vascularity, dlpa improves mood via increased enkephalins, the chocolate increases serotonin and any caffeine sides are balanced out by this. one feels awake and healthy and the ubiquinol with lc-fumarate give a significant increase in endurance.
this is something i would utilize over almost any premade preworkout there is. if cost is pohibitive stick to coffee, chocolate, dlpa and lc-fumarate. this alone will significantly increase performance.
