I was scared to buy from a new company but my old one stopped selling what I was using. Really glad I found this company. Seems like it ships out of Orange County so get it the next day or two. Seems to be working the same and the price is right. I will be trying the other ones soon. Ty

    Fast shipping, great prices, quality product

    I was nervous because I noticed the 1-2 shipping option had been removed which was previously $15 I believe. I would pay it because it was worth it and never late. However, since I bought over a certain amount, I got free shipping which didn’t specify when I could expect the delivery. I still received my package in 1-2 days! Product quality and packaging was great as always. I love this company. They are the best! And so affordable since I am a teacher and don’t make a ton of money.

    Fast shipping and their products WORK

    Fast shipping and their products WORK! Way better and cheaper then any other place I have found. And I do my research! They're also in my state (WA) so I get it within a couple days! $80 bucks for SEMA is a DEAL! Screw the corporations trying to rob us low or fixed income folks. Henry is a good example of taking advantage of people. Charging $300 dollars for something you could get here! That's just crazy. Coastal Peptides is the bomb - low prices, fast shipping, they even at least go out of their way to show you how to use it too! Very happy with them.
