Build Your Own Blend Sports Supplements

  The concept is easy: take a look at your favorite name brand supplements list of ingredients. Chances are you will see a bunch of scientific wording and flashy advertising to convince you that their product is the best. The reality is that each name brand supplement is only as good as its ingredient list, and often times you can buy these same ingredients and mix them yourself for less than a quarter of the price. As you become more knowledgeable with how your body (since everyone is different) reacts to specific supplements, you can adjust the quantities of each ingredient, or the forms of the ingredient (creatine monohydrate, creatine gluconate, creatine AKG for example), and personalize a supplement customized to YOUR body better than the cookie cutter name brand supplement sold to the masses. Even the name brand supplements with 20+ ingredients can be summarized to about 4 or 5 of the most proven ingredients and will be 95%, if not 100% as effective (and sometimes more effective as mixing too many ingredients can have adverse effects on the body). The best part is that because you are not paying for flashy advertising, flashy packaging, research and development, and the countless other expenses that large companies must pass on to the customer, you can Build Your Own Blend for significantly less money.

BYOBss is brand new. You can purchase through our eBay store while our primary online store is in construction. We promise to offer the very best customer satisfaction, 100% pure food grade products, guaranteed fresh supplements, and to pass our savings of using inexpensive (yet effective) packaging and labeling to you, our customer. If you are new to Building Your Own Blend, feel free to send us a message with any questions you may have.


  L-theanine is a precursor compound that is similar in structure to glutamate and glutamine. This amino acid, commonly referred to as theanine, stimulates the brain across the blood barrier. L-theanine has psychoactive attributes on the brain cells, improving mental function. It works well with stimulants such as caffeine, and will even reduce the withdrawal effects from caffeine.

The amino acid was first isolated and extracted from the green tea leaf about sixty years ago. L-theanine in pure powder form provides the benefits of drinking tea on a much more significant level, commonly used in both medical sectors and consumer markets. It has been shown to increase GABA and dopamine levels, leading to stress reduction and increased feelings of well-being.


  • Reduces stress

  • Improves endurance

  • Elevates mood

  • Offsets withdrawal effects of caffeine and tobacco

  • Supports immune health

  • Relaxes body and mind

Scientific Studies

  A study published by the Brigham and Women's Hospital compared immune response between coffee and tea drinkers. The results supported L-theanine's ability to boost disease -fighting gamma delta T cells, improving the general health of consumers.  


  Suggested dosage is 100-200mg.

Synergistic Stacks

  L-Theanine works well in combination with other relaxing supplements. These include GABA, Phenibut and 5HTP.


 Citric Acid – For any BYOB formula, citric acid is by far the cheapest and most effective product for masking the nasty flavor of many supplements and enhancing the flavor of any fruit flavor added (gatorade, crystal light, juice, etc). As an added benefit, citric acid has an important role in the Krebs Cycle, which is basically your body’s process for converting carbohydrates to usable energy. The quantity used highly depends on personal taste, as well as quantity and type of supplement to be flavored. However, standard usage is about 500mg to 3 grams in water with flavor powder (gatorade powder, crystal light, etc).
