Great communication and super fast shipping, items arrived in great condition

Super happy so far... heavy emphasis on the "so far" since I have not started my Chihuahua's research on it yet. COA and documentation was clear and easily found, and cross-referenced on labs site. Lot #s matched the COA's and all bottles, at least to my very untrained eye, are in great shape with nothing inside or outside giving me concern. Plus I love the additional testing I see for endotoxin. Im a fan so far and plan to return for more assuming my Chihuahua dont be deaded afterwards.

Super fast shipping and best pricing yet!

They had a flash sale that I randomly stumbled upon and decided to take advantage to use for my freezer stock. They sell in 3 vial packs, so I loaded up on Reta, CJC / IPA, NAD, GHK-CU. On top of the flash sale, I also used the coupon code here. This was the cheapest I've been able to source any USA vendor product. I placed this order on Friday night at like 10:30pm central time. It arrived on Monday in Dallas, TX. That is FAST! Haven't used the products yet and won't for awhile as again this will be going in my long term freezer storage.

I’m developing a massive Crush!

Have you ever developed a crush on somebody and couldn't help but want to text them? Yeah, that happened to me with this company. After I received my first order, which shipped pretty quickly, I found myself going back to their website several times debating whether or not I should spend the money to buy more stuff. For my money, they strike a perfect balance between price, packaging, convenience, and detailed COAs. I’ll probably continue to buy from these guys.

GLP3-R kit

I am very please with this product. It has changed my life. The 10 vial kit did not take long to come in. They have good rep for testing if you dont want to buy direct and then have to send for testing. I am already planning another order. I also have asked and working with customer service and it has been a great experience. I am new this and highly recommend them.
