TESTOSTERONE NATION | D-Aspartic Acid - Page 1
Personally I wasn't satisfied with dspark, for a while I liked it but after about a week of using it at 3 caps a day I noticed I was feeling soft and lethargic and holding more water. I dropped the spark and it went away. It's funny , I can run good doses of test without worry but any kind of natural test booster seems to have negative effects on me.
I checked the article, there isn't much more than a copy and paste job there - no real science or bloodwork. You clearly said "D-Spark can cause estrogen and progesterone spikes" (the product) - seems you're a bit confused on the formula, please re-check the formula of D-spark ; it doesn't just have D-ASPARIC ACID, it also has Androsta-3,5-Diene-7,17-Dione. Androsta would be the aromatase inhibitor in the formula.
In terms of your results, everyone is different so I can't comment on your situation, but hundreds of guys have given positive feedback on the product. I sent you a PM to check your order # to see what batch of D-spark you were sent. Maybe HCGenerate is the product for you and not D-spark.
