Semaglutide 5mg reconstituted perfectly
Started 2021 with a fresh order of semaglutide 5mg vials. Reconstitution was crystal clear within seconds with zero particulate matter visible. The COA matched our HPLC verification at 99.1% purity. Shipping to Germany took only six days with full cold chain intact.

Returning customer from 2020 and the quality has only improved. My latest semaglutide order came with even more detailed COA documentation than before. Sigma Audley is clearly investing in their processes.

First-time buyer very impressed with BPC-157
This was my first order from Sigma Audley and I am genuinely impressed. The BPC-157 5mg arrived in vacuum-sealed packaging with ice packs still frozen. Solution was crystal clear upon reconstitution. Our lab ran a purity check and it came back at 98.7%, matching the COA exactly.

HGH 12iu kit verified through Janoshik
Ordered the HGH 12iu kit and sent a sample to Janoshik for independent testing. Results came back at 11.8iu per vial which is outstanding. Packaging was professional with each vial individually cushioned. This is my third order from SSA and they have not missed yet.

Tirzepatide quality is solid for a first order
First time ordering from Sigma Audley after seeing them discussed on GLP1Forum. The tirzepatide 10mg came well-packaged with desiccant packs and cold chain maintained. Purity tested well in our lab. Only minor note is that tracking updates were a bit sparse during transit to Brazil, but the product itself is top-notch.

Placed a bulk order of 20 vials of semaglutide 10mg for our research facility. Every single vial had a perfect lyophilized cake with no collapse or discoloration. We tested five vials at random and all came back between 99.0% and 99.4% purity. Truly pharmaceutical-grade consistency at scale.

Ordered GHRP-6 5mg and GHRP-2 5mg together for comparative peptide analysis. Both arrived in excellent condition with matching lot numbers on the COAs. Reconstitution was smooth for both compounds. The GHRP-2 in particular showed exceptional purity when we ran HPLC in-house. Very pleased with this vendor.

Selank and Semax HPLC results matched COA
Ordered Selank 5mg and Semax 10mg for a neuropeptide comparative study. Ran both through our HPLC system and the purity figures matched the provided COAs almost exactly. The Selank came in at 98.9% and the Semax at 99.1%. Would have given five stars but the inner packaging could use slightly better cushioning for international shipments.

Testosterone and Trenbolone bulk order outstanding
Placed a large bulk order of Testosterone Enanthate and Trenbolone Acetate for analytical reference standards in our lab. Both compounds arrived with full COAs including mass spectrometry data. Purity on the Testosterone was 99.5% by our verification. The Trenbolone was equally clean. SSA is our go-to for reference-grade materials now.

HGH 36iu kit COA was spot-on
Received our HGH 36iu kit order and immediately sent two vials for third-party testing. Results came back at 35.4iu and 36.1iu respectively, which is within expected variance and matches the COA beautifully. The packaging was upgraded from our last order with better foam inserts. This is the kind of batch consistency that keeps us coming back.

Reliable vendor with quality products. My tirzepatide order was well-packaged and the purity was confirmed through our lab analysis. The only reason for four stars is that international shipping to the UK took longer than expected this time around.

Retatrutide passed Janoshik testing with flying colors
Sent the retatrutide 5mg sample to Janoshik for independent third-party analysis and it came back at 98.7% purity, which closely matches the 98.9% on the COA. Very impressive for a newer compound. The only small note is that I would appreciate slightly more detailed reconstitution guidance included with the product, but the quality speaks for itself.

MOTs-C quality is good but shipping was slower
The MOTs-C 5mg compound itself is excellent quality with clean reconstitution and purity verified at 98.6% in our lab. However, shipping to South Korea took fourteen days this time, which is longer than the seven to ten day window I was quoted. Product quality earns top marks, but the transit time brings my overall rating down slightly.
