My experience from researching a true compounding pharmacy like Seema compounds Has been beneficial to my overall experience. From the ordering process choosing what peptide to use to deliver to my home was very seamless. I have re-ordered and I’m very happy with the products that I’ve received.

Ordering was very easy thru the sigma website. Order arrived in a timely fashion and was well packed. Follow-up from sigma was also a nice feature. Cannot comment on my response to the compound because it is still to early.

Great Customer Service from ordering to tracking to delivery. I use 2 products bpc-157 & pt-141 both work amazing & quickly. I'm 100% satisfied & on my 3rd round of ordering.

I placed my order and paid the invoice and was waiting for my delivery. I thought maybe there was just a delay in delivery from the various weather issues going on and it was running a day or 2 late and had to leave for a few days for work but figured it would be there by the time I returned home. When I returned and it hadn’t arrived I started looking into it and discovered my order was placed on hold even though it was paid for. Which once I notified Sigma Compounds it was corrected and shipped and should be receiving them tomorrow (even though I ordered these on Labor Day and it’s now the 21st). However the previous order went smooth and the quality was great quality. So it is unsettling regarding placing another order just because of the shipping and delivery.
