Great service from start to finish

Review for Apex Research Peptides →

Grabbed some AOD-9604 during their last restock and it was spot on. Reconstituted perfectly clear with no haze or particulate whatsoever. Order confirmation was instant and it shipped within the hour. A solid supplier that I'll keep using.

Disappointing all round

Review for Halcyon Research Chemicals →

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.

Great service from start to finish

Review for Sterling Peptide Co →

Grabbed some AOD-9604 during their last restock and it was spot on. 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.

Arrived damaged and leaking

Review for Lindenhof Biosciences →

Tried this supplier for Semaglutide and won't be returning. Two of the vials were missing from the order entirely. Two emails to support went completely unanswered. Cannot recommend on this experience.

COA matched the batch

Review for Kestrel Research Labs →

Needed 5-Amino-1MQ at short notice and they came through without a hitch. The lyophilised powder looked right and the vials were properly sealed. Order confirmation was instant and it shipped within the hour. Will definitely be reordering.

Exactly as advertised

Review for Halcyon Research Chemicals →

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.

Good value without cutting corners

Review for Brightwater Peptides →

Restocked on Melanotan II and everything was handled professionally. Third-party analysis was in the box and the purity checked out. Tracking was accurate the whole way and the packaging was discreet. No complaints at all, exactly what I needed.

Arrived damaged and leaking

Review for Vantage Research Peptides →

Gave them a go for Ipamorelin but it really didn't go well. Independent testing came back well under the stated amount. They offered store credit only, not the refund I asked for. Won't be risking another order.

First time ordering Retatrutide from this supplier and they genuinely impressed me. Reconstituted perfectly clear with no haze or particulate whatsoever. Order confirmation was instant and it shipped within the hour. Easily one of the better vendors I've tried.

Disappointing all round

Review for Redwood Research Chemicals →

Gave them a go for AOD-9604 but it really didn't go well. The solution stayed cloudy on reconstitution with visible particulate. The advertised same-day dispatch turned out to be five days. A frustrating waste of time and money.

Refund process has been a nightmare

Review for Albion Peptides →

Tried this supplier for Ipamorelin and won't be returning. There was no cold pack despite paying extra for cold shipping. Dispatch took over a week with no tracking updates. I'll be taking my research budget elsewhere.
