Impressed for a first order

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. Easily one of the better vendors I've tried.

Excellent purity and quick dispatch

Needed Ipamorelin / CJC-1295 at short notice and they came through without a hitch. Mass spec and HPLC numbers on the certificate lined up with what was advertised. Delivery was quick and everything was well protected in transit. Happy to recommend them to other researchers.

Impressed for a first order

Restocked on PT-141 and everything was handled professionally. The certificate named a real testing lab and the batch number matched the vial. Customer service answered my query within a couple of hours. No complaints at all, exactly what I needed.

Trustworthy UK supplier

Ordered Semaglutide for an ongoing project and the whole process was smooth. The lyophilised powder looked right and the vials were properly sealed. Tracking was accurate the whole way and the packaging was discreet. A solid supplier that I'll keep using.

Excellent purity and quick dispatch

Restocked on BPC-157 / TB-500 blend and everything was handled professionally. The batch-specific COA was included and the HPLC figures matched the listing at 99%+. Tracking was accurate the whole way and the packaging was discreet. Easily one of the better vendors I've tried.

Disappointing all round

Bought Melanotan II here and ended up regretting it. One vial arrived cracked with the stopper dislodged. Dispatch took over a week with no tracking updates. Deeply disappointing for the price.

Grabbed some Melanotan II 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. Happy to recommend them to other researchers.

Clean reconstitution, no issues

First time ordering PT-141 from this supplier and they genuinely impressed me. Third-party analysis was in the box and the purity checked out. Shipping was prompt and the packaging kept everything properly cold. No complaints at all, exactly what I needed.

Refund process has been a nightmare

Ordered PT-141 expecting the advertised standard and was let down. The advertised COA never materialised and they couldn't produce a batch-specific one when asked. The refund process has dragged on for weeks with no resolution. A frustrating waste of time and money.

Good peptide, patchy delivery

Picked up BPC-157 here; some good, some not. Product quality was perfectly acceptable, but delivery was a couple of days slower than advertised. Fine for the price, nothing special.
