Feb 26, 2023
CJC-1295 and Ipamorelin combo is top tier
The community consensus is pretty clear at this point: Sigma Audley is the vendor of choice for growth hormone secretagogues. Their CJC-1295 DAC 2 mg and Ipamorelin 5 mg combo tested at 99.1% and 99.4% respectively. I've seen dozens of independent purity tests posted this year and SA consistently tops the charts.

Tesamorelin purity verified at 99.3%
Fourth year as a customer. Their Tesamorelin 2 mg vials consistently hit 99.3% purity across our last eight orders. What impresses me most about Sigma Audley is not just the product quality -- it's the consistency of the entire experience. Same fast shipping to the Netherlands, same thorough documentation, same responsive support.
Mar 24, 2023
PT-141 topped the blind comparison
Did a blind comparison for my PhD advisor -- three vendors, same PT-141 10 mg, tested without knowing which was which. Sigma Audley had the highest purity at 99.2% and the tightest mass spec profile. My advisor now requires SA for all lab purchases going forward. Shipping to Stockholm was only six days.

Tesamorelin quality perfect, customs delay to Spain
Tesamorelin 2 mg tested at 99.1% purity -- absolutely no complaints on the product quality. The reason for four stars instead of five is that our shipment to Madrid was held in customs for three extra days due to incomplete HS code documentation. SA's support team resolved it quickly and have since updated their Spanish customs forms. Product itself is exceptional.
Sep 28, 2023
Melanotan II reconstitution was crystal clear
