I have to agree, they are definitely pricy. However, not 3 weeks ago they had a 50% off deal with a code from Facebook. I took advantage of this and purchased the Glutamine Chews. Essentially, I got 2 tubs (90 servings) for $29.99 shipped.
Let me tell you, at that price I found it difficult to find another product with a comparative price/quantity ratio. The taste is outstanding, and it's nice to have something other than another pill or drink to swallow to get my supplement in. When I can get them on a deal like that again, I will definitely get more. At full price though, or even with a 15%-20% discount, it's just not cost effective for me.
My preferred lineup is:
Pre-Workout: N2KTS
During: Scivation Xtend
Post- Workout: (4) Power Chews Glutamine, (3) Gear, 16oz shake (Whey to Build Muscle Ice Cream Sandwich blended w/ a banana, and mixed with almond milk).
