Everything came as promised and the vials were properly protected. I appreciated how fast the tracking updates were. The labels were clear and the batch numbers were visible. Support chat was helpful when I had a quick question. Would buy from them again.

The entire order process was straightforward and the communication was clear at every step. Both vials arrived in excellent condition with no signs of temperature exposure or mishandling. I verified the contents against the product sheet and everything matched perfectly. The customer service representative I spoke with was knowledgeable and patient. I would not hesitate to place another order.

Tesamorelin 10 mgMOTS-c 10 mg
the tesa vial had a small chip on the base that i noticed when i set it down. i took a pic and texted it to support and they said they would send a replacement. the motsc was perfect and the shipping was fast. a little annoying with the chip but the way they handled it made it not really a problem at all.

Tesamorelin 10 mg
This was my first time buying from Aion. The checkout process was simple and I didn't have to create an account if I didn't want to. The vial arrived in a padded envelope with a cold pack. The label was clean and the seal was intact. I didn't have any questions so I didn't use support, but the automated emails were helpful.

I ordered these two items and they arrived in the same box. The Tesa vial was in a small plastic tube and the NAD+ was in a padded envelope. The labels were clear and the seals were intact. I didn't have any questions so I didn't contact support. The shipping was fast and the tracking was accurate.

the tesa vial had a slightly loose cap that i had to tighten before storing it. not a big deal but a little annoying. the shipping was fast and the box looked good on the outside. support said they would look into the cap issue for future batches. otherwise all good.

The tracking status displayed "exception at facility" for a full business day on July 14th, which initially concerned me that the package might be delayed further. It cleared by the next morning and was delivered within the original estimate. Both vials arrived in acceptable condition, though the NAD+ carton had a minor abrasion on one corner. I contacted support to confirm there was no temperature excursion during the hold and they provided a brief, professional response. Acceptable service, minor delay.

GHK-Cu 50 mgTesamorelin 10 mgBPC-157 20 mg
placed this order for my brother who does his own research and I included the product names in the shipping notes so he could match them. He called me back and said "the stuff looks legit, the seals are factory pressed not just capped." I think that is the highest compliment I am going to get for choosing a vendor. Three vials, no damage, arrived in two days. Aion is now the default for our group.

i had to call the carrier to reschedule delivery because i was at work all day and i did not want it sitting in the sun at 105 degrees. the tesa and nad+ both made it through fine after the reschedule. the box was sealed when i got it, vials intact. the whole reschedule thing was more of a me problem than a vendor problem but it added a day to the timeline. no actual damage.

Tesamorelin 10 mgPT-141 10 mgKLOW Blend 80 mg
box showed up at the front desk of my office building around 11am.forgot about it until i saw the notification at 2:40. walked down there, it was sitting in a bin with like thirty other packages. no identifying info on the front of the box besides the tracking barcode so i just matched the tracking number from the text i got. three vials inside, all in good shape. the tesa cap was a little stiff to unscrew first time but that is probably just the seal not a defect. no leaks, no discoloration, labels were all readable. support not needed, tracking was accurate, delivery was next day. fine.

Tesamorelin 10 mgNAD+ 500 mg
the delivery text came through at 4:02pm saying "delivered to your door" but i was in a meeting and my apartment is on the second floor and i did not get home until 6:10. so the tracker said delivered but i had no idea where it actually was for about two hours. found it under the little concrete ledge at the base of the building stairs, not under my door or at the front entrance. no damage to either vial, both sealed, tesa was in a tube and nad was loose in the box. i did call support just to ask if they could update the delivery notes for my records and the rep was fine about it, no big deal. just the time gap between the text and me actually holding the thing was longer than i would have liked. the products were fine, the tracking timestamp was just off by a couple hours.

MT-2 10 mgGHK-Cu 50 mgTesamorelin 10 mg
i am going to get this over with quickly. three items, all present, all in tubes, all cold. the mt2 tube had a small gap at the top where the plastic film liner was not heat sealed all the way around, maybe an eighth of an inch. i check these every time because a torn liner means air gets to the cap and the cap integrity matters over time. i felt around the gap, the seal was holding, no air movement, the vial was not exposed. i called support on the first day just to flag it for their qc notes and they thanked me and said they would run that liner supplier through a calibration check. nothing i needed to do, no return, no replacement. the other two were perfect. so. the mt2 liner had a small gap and they let me know they would look at it. that is the whole review and i am not going to pad it.

GHK-Cu 50 mgTesamorelin 10 mg
i set the ghkcu aside for about four days before i got around to sending it to the lab because i was at a job site and the courier pickup window was closed all week. it did not budge at all, the cap was solid, no precipitate in the liquid after four days at room temp which is not the ideal storage but it is within the manufacturer stated stability window for short excursions. the tesa went in the same pick up, they do both in the same submission batch so it saved me a courier trip. results came back tuesday. ghkcu at 99.0% and tesa at 98.4%, both within the published assay ranges for their respective lots. the lab did not flag anything above a threshold or below a threshold. i compared the method they used, hplc with uv detection at 214nm, and it is the standard pass. no problems. the lot numbers on the labels matched the certificate of analysis i pulled from their site. so. lab confirmed, storage held, no anomalies.

Tesamorelin 10 mgGHK-Cu 50 mg
the inner cardboard tray that held the two tubes had a corner that was not cleanly die-cut, there was a little burr of cardboard sticking up about two millimeters at the top right corner of the tray well for the tesa. i opened the box and it snagged the corner of the tesa label when I lifted the tube out, leaving a shallow scratch in the printed text, not in the adhesive, just the ink layer. the tesa label still read cleanly, i could make out every character, but the tesa product name now has a thin white line through the middle two letters. i photographed it and sent it to their support before i put the vial away. they confirmed it was a known trim defect from the last run of those trays and offered a replacement tesa at no charge, which i accepted. the ghkcu label had not snagged because its tray well was clean, and the water was unaffected. the replacement tesa showed up in two days, printed on the same tray stock, no burr. so the original had a small cosmetic scratch from a cardboard edge and the replacement was clean. nothing was wrong with either vial, it was just the label paint.
