My TOP Choice

I've ordered (so has family) dozens of times. Always ships quickly, good COMMS regarding shipping/order status, just that USPS is not as reliable as FedEx so I've had to wait a few extra days...just keep that in mind.

They went through some weird billing changes and the whole stupid/lame KYC crap, and the last time my order said "purchased from" some Chinese name, which was kinda sketch tbh. I went to Southern and for same identical product (after discounts from both Penguin and them), I paid $166 for NAD+ and it was gonna be $291 from Peng. So guess I'm saying - shop them...but they've always been reliable so maybe it's worth paying 75% more? Food for thought.

Solid Peptides + Fast Shipping

I got CJC no dac / Ipamorelin and Melanotan 1. Both work as expected. If test results for a peptide are old you can request new tests and they will send it off for testing asap. The customer service is so much better than other more popular companies. My CJC/Ipa and Melanotan from EZ Peptides seemed week. I can feel the rush with a lower dose with the CJC/IPA from Eros and the melanotan gives me the nausea within minutes with noticeable results.

Shipping was fast and the vials were shipped in a case.

Pricing is also competitive. You likely won't find a quality to price ratio like theirs unless you buy in bulk from a wholesaler and pay to have them tested yourself.

FANTASTIC First Time!

Found they had solid pricing on NAD+, and then saw they had Re*a GLP. Compared to my usual/VERY reliable (Penguin), I ran side-by-side and for 2 500mg NAD+, 1-30mgRe*a, it was $166 vs $291!!!! That was with discounts for both vendors. Southern’s documentation, testing and safety is TOP of the class and they’ve become my new go-to and HOME! Both products VERY legit VERY solid! Give em a shot (pun intended)! 😬

Slight slip up, AWESOME response!

Made an order over the weekend, my bank wouldn't let me Zell pay until Monday. Wednesday comes and I get no response from Puratek, I forwarded the email to them from my bank with the Transaction ID. Response in less than a half hour from "Tony", expedited the shipping to overnight and made sure to send it out TODAY! Also game a code for an additional 10% on any future order for the inconvenience!!!
I don't know if it stacks with PePC's code but next time I'm buying I'll give it a shot and be happy to do business with them if it does or not :)

Couldn’t ask for better customer service and integrity!

I ordered Some dihexa capsules for my elder monkey and found out it was too strong for her age. I tried to cancel b fore it shipped. It showed up at my door so I emailed and explained my situation if I could exchange it.
No problem just pick something else and we’ll send it they said. So I let them know and they shipped out same day without me returning the item. I did return the product and day later my new package arrived with extra stuff too. I was blown away with the confidence and super special customer support! I’d like to see someone top these guys. Great prices too. 🍺 to them.

Great quality and fast shipping, for real!

Excellent company with a professional website and I love that they have little QR codes on every bottle that pull up the COA. Would definitely buy from again.
