customer service was rude
Richard D.

My package got stuck in transit for two weeks and when I emailed to ask what was going on, the reply I got back was short and frankly dismissive. No offer to help track it down, just basically told me to wait. The product eventually showed up but the way I was treated left a bad taste. Would think twice before ordering again.

solid reorder
Douglas R.

Second time ordering the Ostarine. Same packaging quality, same quick turnaround, third-party COA matched up. Consistency counts for a lot with me so I'll keep coming back.

they actually pick up the phone
Regina B.

Had a question about my shipment and called the number on the site fully expecting voicemail. Someone real answered and walked me through the tracking. After years of ordering research chems from places that ghost you, that alone earned the five stars. The Cardarine itself arrived two days later, vials bubble wrapped tight, COA right there on the page. Smooth start to finish.

decent, COA wasn't batch specific
biohack_miles

Product came well packed and quick. My only gripe is the certificate they linked looked like a generic one rather than tied to my actual lot number. I'd rather see the exact batch tested. Otherwise an okay experience.

fast shipping
Austin O.

Order went out same day and landed on my doorstep in under a week. Discreet box, nothing on the label. That part they nail.

broken bottle, had to pay to return it
Vivian I.

One of the two dropper bottles showed up cracked and leaking. The annoying part wasn't the breakage, it was being told I'd have to cover return shipping to get it sorted. Felt backwards for something that wasn't my fault.

fine but the price went up
Adrian G.

Bought from them before and the Ostarine was the same as last time, packaging was solid. Just noticed the per-bottle price crept up since my last order. Still got the testing docs though.

COAs for every batch
victoria895

Ordered the Cardarine and they had a batch-specific COA posted right on the product page. Bottle was bubble wrapped, arrived in five days. No complaints.

quick shipping, COA matched
Grant P.

Terse review: ordered RAD-140, shipped fast, lab report lined up with the batch. Reordering.

plain packaging, product ok
carolyn.l.biohack

Box was pretty bare-bones and the vial just had a basic label, but the YK-11 itself looked fine and the COA was on the site. Middling, does the job.

dependable vendor
Corey H.

Ordered MK-2866, arrived in five days, packaging was solid and the label had everything I needed. Good experience.

happy with the COAs
Daniel Y.

I always check the third-party report before buying and theirs are current. Cardarine came clear and properly sealed. Quick delivery too.

easy reorder
Miles Q.

Second time ordering LGD-4033. Site was easy to use, shipping quick, vial labeled with batch info. Would recommend.

slow to reply to email
Zachary D.

Took about three days to get an answer to a question on my order. Not terrible but I've had faster. Product and shipping were fine.

price went up but still worth it
Vivian P.

Noticed prices crept up a bit since my last order, but the lab transparency and fast shipping keep me coming back. Ostarine arrived sealed and clean.

good packaging
Robert O.

Stenabolic showed up double-bagged and bubble wrapped. Nothing leaked or shifted. Took about a week.

reliable every time
Reid W.

Fourth order. Shipping speed and packaging have been consistent, and they always have a lab report to point to. Trust them.

out of stock a lot
Sean Q.

Wanted the RAD-140 twice now and it's been out of stock both times. When I did get an order through it was fine, just wish they kept inventory up.

no complaints
Roger P.

Ordered Andarine, came packaged well, labeled clearly, arrived on time. Does what a good vendor should.

free shipping is nice
Mark S.

Crossed the $75 threshold for free shipping and still got it in five days. COA available for the MK-677. Good vendor.
