I have noticed a huge improvement in my over well being since I started taking this. Good energy and endurance at work with physical activitiesI'm almost done with my first bottle and I've already noticed an increase in my stamina, especially when lifting and running. The GF has noticed too. ;-) I will definitely be purchasing a refill! I also want to add it's easy on the stomach and won't make you fart a lot unlike some other supplements I won't name. I highly recommend this supplement!Easy to swallow, natural t boost that was easy to feel after about 7 days of use.I have completed my first bottle of Primal Shield and am ordering a 2nd cycle. I am middle aged and Primal Shield have me more energy and motivated me to work out harder. I can see the results.Quality products and doesn't give the annoying hair growth in the ears and nose..Aids in fast recovery and will definitely purchase againIts too soon to tell the full potential of this product but within a few days I noticed i had more focus in the office. My sleep habits seem to be balancing out. My overall fatigue is diminishingI will be ordering moreThere's so much goodness packed into this one supplement. Saves having to purchase separate supplements. Many great estrogen regulating ingredients in this formula. I've experienced noticeable muscle mass increase and definition since starting this supplement with minimal exercise. Anyone capable of doing a consistent workout regime should experience fantastic results.Ingredients list is important to me as I must review all ingredients so they don't negatively impact current medications. The transparency of the ingredients list is appreciated so I leave nothing to chance.I liked this formulation so much I am now trying their Primal Shield and Qi Tonic/Cortisol Blocker.Was feeling a little sluggish during the day, & having a hard time getting to sleep at night & generally feeling off my game in the gym & in my life so I did some research & started taking this supplement because everything about it was signifying a quality product.After my 1st bottle I have definitely noticed improvements in all the aforementioned areas. I have now ordered a second bottle feeling very encouraged to continue the progress.
