Ascend science is a top notch peptide company! Quality is 10/10, lot of testing done to make sure compounds are safe for their customers and the owners are great. Any questions I ever have they reply to texts super quickly and orders arrive in 1-2 days. Highly recommend Ascend to anyone interested in peptides
I have placed two large orders. I like the fact that they have 2 day shipping and you can decide if you want Fed Express or UPS. On my second order I paid using Venmo. You are supposed to put your order number in the notes of the Venmo. Somehow I didn't see that. I texted them not during business hours and they replied immediately telling me not to worry and they would take care of it. Which is exactly what they did!! Have recommended them to everyone that's interested in peptides and even some that don't have any idea what peptides do.
I order from ascend at least twice a month. I will say I have had accidents where I am maybe missing one of 10 things I ordered, but they are top notch customer service! Over nighted my missing item. I would recommend this company to anyone! They stand behind their products, and so do I
Product is amazing!! I’ve been purchasing from them for a few months now and can’t be more pleased with the product and customer service. Always receive my order within 3 days. You won’t be disappointed with this company
I have spent $1,400.00 over the last 3 weeks with this company and was concerned about batch numbers and test results, and the lack thereof on the orders received. I have called them multiple times and emailed them 4 times with no reply at all. There are several other brands in the industry that have great customer service and provide QR codes on the bottles shipped that take you to the test reports with matching batch numbers. I would strongly recommend staying away from this company for your research peptides.
That was a fast reply. It would have been nice if you replied to my 5 phone calls and 4 emails... Feel free to check your orders; reference my order numbers: Order #AL-16937169, July 26; Order #AL-58189591 · Jul 31, 2026. I have emailed to your posted email address support@ascensionlaboratories and have called the number on your site 904-907-4610, which reaches a generic mobile voicemail

Hey Tony. We just checked our system, we do not have any Tony that has spent $1,400 in the last 3 weeks. We also aren't seeing a Tony that has emailed us, called us or texted us within the last 3 weeks. Additionally, we answer every phone email, call, and text within 2 hours after receiving it. Maybe you have been doing business with another company and have mistaken them for us.
Update reply:
1) You placed two different orders under two different names, and two different addresses.
2) You emailed the wrong support email, that is not the email posted on our website.
3) We don’t have any missed calls from your cell on our business line.
4) Additionally, our labels are mass printed. Adding lot numbers to the vial is new, which we are working on implementing. However, if you look at our COA’s we are constantly updating them with new batches. All of them are verifiable through the lab we had tested with on their official website.
I do apologize for the poor experience, however I don’t feel like we had a fair chance of helping you. We would still love to offer you help if you are interested.
Fast delivery, knowledgeable regarding product. Great service.

Ascend Science is legit! What else can be said…Thank you guys!
I've placed 25 orders (and counting) with Ascend Science and have received all products as advertised in either two business days or next business day depending on my shipping selection. All products have exeeded my expectations and any time I needed to contact them to change an order they responded within minutes to no longer than 3 hours. They even respond after hours and weekends. Entirely satisfied and am continuing to use them
Highly recommend
