I recently purchased your book and in it you suggest Resveratrol, Deer Velvet Antler, Tribulus terrestris, d-Aspartic acid, and Saw Palmetto supplementation for us "older" guys to help naturally increase our testosterone levels - however, you do not say how much or when to take the supplements - any recommendations? - I am 59 - great book BTW
Regarding the supplements - Since these are supplements that don't have the same "official" FDA requirements and recommendations as vitamins and minerals ... there is some room for experimentation here.
However most all the manufacturers comply the same Daily Suggested guidelines for these, so you can usually follow the minimum and maximum amounts they have on the label.
Also as a good practice it is best to spread most supplements out. The idea of a 24 hour release pill is not really that accurate So for example if you have a choice to take 2- 500mg pills spaced 12 hours apart or take a bigger one-a-day type pill which claims to be time released, it is better to control the "time releasing" yourself by spreading out the consumption of the pills.
The various pre-workout products do offer SOME assistance in losing weight , but really it is more like icing on a cake. At most, they may contribute 5-10% extra help.
Products like LIPO-6 and the ones you referenced tend to use the same combinations of Caffeine, 7-KETO DHEA, Synephrines and other similar compounds. They are mostly all the same and none of them are really revolutionary or special.
