Great service from start to finish
Review for Halcyon Research Chemicals →Picked up 5-Amino-1MQ here after a recommendation and wasn't disappointed. Reconstituted perfectly clear with no haze or particulate whatsoever. Tracking was accurate the whole way and the packaging was discreet. Will definitely be reordering.

Disappointing all round
Review for Lindenhof Biosciences →Gave them a go for NAD+ but it really didn't go well. The advertised COA never materialised and they couldn't produce a batch-specific one when asked. They offered store credit only, not the refund I asked for. Deeply disappointing for the price.

COA matched the batch
Review for Sterling Peptide Co →Picked up TB-500 here after a recommendation and wasn't disappointed. The lyophilised powder looked right and the vials were properly sealed. Delivery was quick and everything was well protected in transit. A reliable option for UK-based research.

Exactly as advertised
Review for Halcyon Research Chemicals →Restocked on Tirzepatide and everything was handled professionally. Mass spec and HPLC numbers on the certificate lined up with what was advertised. Shipping was prompt and the packaging kept everything properly cold. Will definitely be reordering.

Trustworthy UK supplier
Review for Greywell Research →Needed CJC-1295 at short notice and they came through without a hitch. Third-party analysis was in the box and the purity checked out. Shipping was prompt and the packaging kept everything properly cold. Happy to recommend them to other researchers.

Arrived damaged and leaking
Review for Northgate Labs →Bought Semaglutide here and ended up regretting it. Two of the vials were missing from the order entirely. The advertised same-day dispatch turned out to be five days. A frustrating waste of time and money.

Clean reconstitution, no issues
Review for Ravenscroft Bio →Grabbed some AOD-9604 during their last restock and it was spot on. The batch-specific COA was included and the HPLC figures matched the listing at 99%+. Dispatch was same-day and it arrived the next morning with a cold pack. Will definitely be reordering.

No COA despite advertising one
Review for Brightwater Peptides →Ordered Retatrutide and the experience fell well short of what was advertised. The solution stayed cloudy on reconstitution with visible particulate. Dispatch took over a week with no tracking updates. Deeply disappointing for the price.

Excellent purity and quick dispatch
Review for Larkfield Peptides →First time ordering Retatrutide from this supplier and they genuinely impressed me. The lyophilised powder looked right and the vials were properly sealed. Shipping was prompt and the packaging kept everything properly cold. A reliable option for UK-based research.
