AOD-9604 and Peptides made simple
I'm currently taking the AOD-9604 and couldn't be happier. I was actually recommended Sigma Compound by my doctor which was a relief because I was hesitant of buying peptides online. Combined with the diet and exercise I have dropped 50lbs in two months. Reading their books Peptides made simple (usage, dosage & More) and the Reconstitution Encyclopedia. It made it all make sense and help me on how to take exactly what I needed.
Solid selection
Solid selection, quick shipping and customer service is top notch. Had an order issue and they corrected it with in a day. Didn’t have to run through a bunch of automated messages just to get put to the back of the line. Email was smooth and seamless. Great company

Great company their education books are great help. I appreciate the knowledge they help get out there.
Great products, great service
I sent a message to support with a slight concern and some questions. They jumped right on it. Not only did they go back & forth with me, but I had a follow up call from the owner (CEO?) to ensure I was clear. The products are great, the service is outstanding. They know how to treat their customers.

Satisfied customer
Im fairly new to the Peptide market, Sigma being my third vender. Im impressed with the shipping and customer service! Packaging is Plautium level!!! I purchased the 10/10 Bp157/ TB500 nasel spray and could not be happier. Im reading Sigma recommend books and they are educational and easy to follow! Looking forward to doing business in the future.
Customer experience exceeds expectations
I had a great experience ordering from Sigmacompounds.com. The ordering process was fast, efficient, and very professional from start to finish. My peptides order arrived within a week, which exceeded my expectations. The packaging was exceptionally well done—clearly designed to protect the products and noticeably better than what I’ve seen from other competitors in this space. Overall, a smooth and reliable experience, and I’ll definitely be ordering again.

I just received my order today
I just received my order today. It was well packaged with the ice pack. The bottle and nasal spray were packed in another box with additional padding. However, the ice pack has already melted and was at room temp by the time I received it on 01/30. From the shipping tracking info, it looks like it was picked up by the carrier on 01/26. Hopefully, this does not impact the quality of the peptide. My only complaint is they don't have faster shipping options at the time I ordered it. I hope they add it in the future. Also, I suggest the nasal spray to be plastic wrapped to ensure its sterile. It does have a cap so its no big deal.
