If you've been here before, you know that I don't use a lot of supplements. Frankly, most of them are wastes of hard-earned money. However, there are some supplements that are worthwhile – they simply work.

Supplements are costly, though. So every little bit helps – here are some coupon codes for Bodybuilding.com:

Homemade Supplement Secrets

I just finished reading Jeff Anderson’s Homemade Supplement Secrets, and it’s really quite good. Nearly 200 pages, the book (in PDF) is brimming with useful information. Things like the deceptive advertising and product claims that some supplement manufacturers make, the links to bodybuilding magazines, key ingredients in the most effective supplements, and — most importantly — how to make your own supplements!

All in all, buying Homemade Supplement Secrets is money well-spent: In many cases you can save over 90 percent on the cost! In fact, make one of your own supplements that mimics a popular supplement and you’ve doubled your investment!
