decent prices
Brian K.

Got my GHK-Cu for noticeably less than two other vendors I'd been comparing, and the bulk discount helped. Packaging was very plain, just a padded mailer with no cold pack, but the powder was intact so no complaints there.

no response, no package
Grant J.

Spent close to two hundred dollars and two weeks later I have nothing. Tracking never left the origin facility and the support inbox might as well not exist. Used to hear good things about this place but whatever changed in the last year has not been good for customers like me.

outdated COAs
pamela496

My main gripe is the certificates. They dated to forever ago and none of them matched the batch I actually received, so there's no real way to verify what's in the vial. Shipping itself was fine.

used to be reliable, not anymore
joseph38

I ordered from Peptides Warehouse for a couple of years without a single problem, so I had no hesitation placing another order in May. This one never arrived. Tracking stalled, emails went unanswered for weeks, and there was no offer of a refund. Whatever changed internally has wrecked what used to be a dependable vendor and I can't recommend them now.

fine, nothing special
Maria Z.

Order arrived in about four days, vials looked okay and were filled to where they should be. The COA on the site was years old though so I'm basically taking the purity on faith. Middle of the road.

still waiting after three weeks
Beatrice M.

Ordered TB-500 and a couple bottles of MK-677 on the 12th. Got a confirmation and a tracking number that never updated past the pre-shipment scan. Three weeks now, six emails, two of them got a one-word reply and that was it. I'm not calling it a scam but the silence once they have your money is genuinely awful and I won't be back.

cheap but slow
Ryan U.

Pricing on the BPC-157 was good and the flat $9.95 shipping is fair, but it sat on a Florida label for nine days before it actually moved. Got there eventually.

pricier than competitors
Curtis V.

Their BPC-157 runs noticeably more than other sources I've checked. Shipping was quick but the value just isn't there anymore.

where are the test results
jose769

The only certificates on the site are ancient, like 2014 old. For a vendor this size you'd expect batch-specific COAs by now. Shipping was fine though.

been ordering for years
ashley_daily

Ordered from these guys on and off for about three years now. Shipping is always quick and the packaging is discreet. No complaints from me.

still waiting
Betty S.

Placed an order over a month ago, no tracking that updates and no answer to my emails. Not what I expected.

support is hit or miss
Leah W.

Got a two-word reply after several emails about my Sermorelin order. The product itself shipped fine but communication needs serious work.

no response from support
Nicole O.

Emailed support five times over three weeks about a missing item and got nothing back. Really frustrating when you've already paid.

underfilled vial
Nancy Z.

One of my TB-500 vials looked clearly underfilled compared to the others in the same order. Reached out, no reply yet.

fast shipping
Grant V.

BPC-157 showed up in 3 days, vials sealed and labeled fine. Wish they had current COAs but the shipping speed is hard to beat.

wrong address, no refund
Aaron B.

They shipped my order to an old address even though I updated it at checkout, and support wouldn't help sort out a refund. Disappointing.

plain packaging, slow replies
william_study

Order arrived but packaging was pretty bare bones, no padding around the vials. Asked a question through the contact form and never heard back.

ok experience
coach_lauren

Ordering was easy, like checking out on Amazon. Got my CJC-1295 in about 4 days. It's fine, just nothing that stands out.

good prices, decent service
Priya A.

Prices are reasonable and they ship quick. Ipamorelin vials looked clean and the lyophilized cake was intact. Would order again.

Mixed feelings about this order
Frank Carson

Ordered BPC-157, Melanotan II, and TB-500 for research. Products arrived and seem legitimate based on the COAs provided, but it took 11 days to ship out after I placed the order. No explanation why. The packaging was fine, everything was sealed properly. I emailed asking about the delay and got a response 2 days later that didn't really answer my question. Product quality appears good but the slow processing and mediocre communication make me hesitant to order again.
