Overview
Based in Naples, Florida, Nutritional Science Laboratories has been operating since 1993, when it began the Stripeptin line of cosmetic formulas. Although we have seen plenty of online advertisements for Stripeptin products, we cannot vouch for the company’s reputation for distributing quality products, since most of its products are available through third-party affiliates. Stripeptin currently offers two separate formulas for the eye area, one called Stripeptin-DC (for dark circles) and the other called Stripeptin-PE (for puffiness).

Featured Ingredients
Stripeptin-DC is intended to reduce dark circles by using methods employed by other cosmeceutical formulas. According to the company, this formula contains a blend of enzymes that are supposed to help break down pooled blood and other materials that can cause dark circles to form. The formula also contains peptides that are supposed to strengthen the collagen fibers that keep skin firm and tight, while also producing signals that keep muscles contractions from occurring in the hopes of diminishing the formation of fine lines and wrinkles. Unfortunately, Stripeptin does not disclose while enzymes or peptides are included in the Stripeptin-DC formula, so we cannot evaluate its effectiveness.

Stripeptin-PE is formulated to help reduce the appearance of puffiness and under-eye bags. According to Nutritional Science Laboratories, the formula contains a mixture of bioflavonoids, peptides, moisturizers and firming agents that are supposed to calm swollen skin and help reinforce skin to keep puffiness from occurring. However, the company does not specify what the actual ingredients in the formula are, nor does it provide any scientific substantiation for its claims. The team at EyeWrinkleReviews.com is beginning to wonder whether Nutritional Science Laboratories is nothing more than a clever nickname, since the company seems intent on hiding the ingredients in its formulas, which we find troublesome. 

Web Site Description
The Stripeptin web site does a good job of providing plenty of material, except perhaps for the most important information of all. The web site does contain plenty of testimonials and before/after photos of those who have used the products, as well as a clear explanation of how the formula is supposed to work. We also were pleased to find that the product can be tried free for 14 days. Unfortunately, none of this information makes up for the fact that the company does not reveal the specific ingredients in its products, which to us raises serious questions about the integrity of the company and its marketing methods.

Positives
- Plenty of customer testimonials and a clear description of the products- Free trial is available for both eye formulas

 Negatives
- No ingredients are revealed; product cannot be evaluated for effectiveness

- Company does not disclose the results of any testing, if any has been conducted

- Lack of research on the products and its ingredients raise serious questions

Conclusion
Even though both Stripeptin formulas seem to be intriguing products for trying to get rid of dark circles and under-eye puffiness, we cannot recommend either Stripeptin-DC or Stripeptin-PE until the company reveals what ingredients are included in the formulas.
