Great supplier

This is an update to my previous review. I’ve since ordered GHK-CU and Tesamorelin. The customer service and product quality has been excellent. I’ve tried a couple other suppliers as well but keep coming back here.

Great customer service, fast shipping and exceptional product

I’ve had 2 orders with Southern Aminos so far with multiple products. Shipping has been same day of order and it’s been on the “doorstep” within 3 days. Customer service has returned my inquiries within 24 hours. No issues with any of the product order and I appreciate their fair pricing. I have 3 vendors I work with and price check often SA is always right in line with great pricing

Great pricing, fast shipping

I can't comment on the quality aspect yet, but the prices are really good if you buy using their kits. Some of the QR codes on the bottles didn't scan so I had to compare the COAs on the website using the lot #s on the bottles.

Pricing has room for improvement

Ordered some bulk, their prices only make sense at the 10+ but then you’ve already committed to 1K+, there’s absolutely room for improvement. Fast shipping and quality product.’

EPIC VENDOR: HIGHLY RECOMMEND

I’ve ordered at least 4 times already; latest buy was the blend above to play with. Fast shipping. PERFECT PACKAGING. Fun per vial packaging. ABSOLUTELY one of my “go to” vendors .

High priced (w/codes) and slow shipping

Ordered Selank, Semax and the blend. Memorial Day sale. Even with the discount most of the prices are on the higher end. Shipping from CO to East Coast took about 4 days longer than other vendors from CA. Also they require package protection and shipping def has a mark up. Just revisited them for some MOTSC 40mg and used the running code (no stacking) and it worked out to be the exact same retails price after the shipping protection & egregious parcel cost. Would buy from the again if in a bind.
