A few comments:
Imo you want to tweak down the Cialis as low as you can go. For example, it may be decreasing blood flow to your optic nerve - more studywork needs to be done and, in the meantime, I would play it cautious. See if you can get it down to 2-3 mg for example per day. And that, of course, will save you money.
I bought Maca in a Navitas bag and it lasts forever. Quite inexpensive this way even though I took a fair amount.
You can try Citrulline + a source of nitrates (spinach, celery, lettuce, beet root extract) instead of the Neo40. Neo40 will have more horsepower than these probably though, but this is the "poor man's version".
Creatine I but in a big blue container and it lasts forever. The container cost $15 or $20, but it will last me for about four months, so I'm not sure why this would be a big expense?
Ginseng: Buy it off of Amazon is the only way to save money. Make sure you get an "unleaded" product.
Undenatured Whey: Make your own egg whites. Whey (undenatured only) has some nice properties such as boosting glutathione, but, if you want to save money, just make your own protein in a skillet. I'm not a big fan of casein - read the China study for example - but nonfat milk is another option.
CAUTION: Always talk to your doc before adding supplements.
