Customer Reviews
Real feedback from researchers and customers. Every review is tied to a verified purchase.
QUALITY
WHY ARE OTHER PLACES SO MUCH MORE EXPENSIVE FOR THE SAME PURITY. SWITCHED OVER. NO REGRETS.
good, dac version a little finicky
the dac form can clump in some vendors product. theirs reconstituted cleanly but i had to be careful with the swirl. not a 22EXO problem really, just dac in general
KP-10 receptor work
ran on lab hplc, came back at 98.8 which matched their coa. clean ms peak.
Wound-healing assay supplier
Used in a series of full-thickness rat wound experiments. Activity is consistent across the lots we've tested. Documentation is detailed.
good but reconstitution takes time at 500mg
dissolves fully but takes a couple minutes of gentle inversion. quality is there. just plan ahead
Repeat order, repeat quality
Have ordered six times now. Lot variance is minimal. The 10mg per-mg pricing is competitive.
epithalon 10mg is the standard for chronic-dose work
10mg vials are standard for our extended-dose rodent protocols. quality lot. coa attached automatically
blue blue blue
real ghk-cu the way it should look. some other vendors send something nearly clear and you wonder
Stack arrived clean
GHRH + GHS-R agonist combo, ratio appears 1:1 per the COA. Reconstituted clear, no precipitates. Used for pulsatile-secretion experiments. Reliable.
ipa is consistent
third lot in a row that ran 99+ on internal hplc. dont normally write reviews but their qc is the real deal
BPC-157 lot held up
Stored at -20C for 14 weeks before opening. HPLC re-test on opening matched the COA within instrument error. Stability is real here. Will reorder.
tb500 quality
good. clean. fast. nothing else
good, but the cake was a bit denser than expected
MT-II from 22EXO had a denser lyo cake than I'm used to. dissolved cleanly though. purity ran 98.4 internal. no issues with results.
ipamorelin without the bloat of other GHRPs
selective ghs-r1a agonism is what makes ipamorelin different and 22EXO's is high purity. coa attached to the order email automatically.
DAC version reconstitutes cleanly
the DAC formulation can be finicky in some vendors' product. 22EXO's was textbook. cake was uniform white, dissolved in under 30 sec.
Reliable GHRP-6
Clean synthesis. Perfect for GH studies.
Synergy stack ready to go
We typically run BPC-157 and TB-500 in parallel arms in our wound model. The pre-mixed vial is convenient for the combined-arm group. Pre-validated against our internal HPLC protocol — peaks resolved cleanly, no degradation products, no cross-contamination signals.
Solid combo for adipose research
Used in a fat-cell study where both compounds were on the protocol. Pre-blended product cut prep time substantially.
purity good, label has typo
Purity is fine, COA matched. Small thing — vial label spelled the lot number with a lowercase L instead of a 1, made me look twice. Maybe just a sticker thing. Otherwise no complaints.
Reliable
Have been buying sermorelin from 22EXO for over a year. Never a bad lot. Always documented. The fact that they hit deadlines on COA delivery alone is reason to keep ordering.
4 way blend works as advertised
kpv stability in the blend was my main concern but they include a stability statement in the product insert. would buy again. 4 stars only because I'd love a smaller-volume option for pilot studies.
cant beat the value
10mg vials are so much cheaper per unit that it's not even close. and quality is the same as the 5
500mg vials are huge
the 500mg vial is much bigger than i expected. value per mg is really good vs other suppliers. nad+ in this volume is rare.
Reliable
Fourth lot in a row that has met our internal QA spec on first pass. We use a slightly stricter cutoff than the COA spec and 22EXO has cleared it every time.
no complaints whatsoever
It works. Pure. Documented. Cheaper than I was paying. End of review.
good but blend ratio could be more flexible
wish there were 2 ratio options. like a 2:1 and a 1:1. otherwise no complaints. quality is there
preferred over the DAC version for me
if you want the short half life and want to dose pulsatile this is the version. 22EXO's mod-GRF is consistent.
AOD-9604 fragment quality
the fragment 176-191 of human gh is what aod-9604 is. 22EXO's product MS confirmed correct molecular weight.
Reference-grade thymic peptide
Batch consistency is excellent.
good, COA ID peak slightly broadened
Identity peak on our LC-MS was a little broader than the COA's example chromatogram, but mass was correct and purity above 98.2. Nothing actionable, just noting it. Otherwise an excellent product. Will reorder.
LR3 stability is the key and theirs holds up
the long arg-3 variant should resist serum protease cleavage and 22EXO's product has performed correctly in our cell-culture experiments. consistent activity.
good, would like batch reports digitized faster
Quality of the peptide itself is excellent — 99.3% on incoming HPLC, identity confirmed by MALDI-TOF in our own lab. The COA PDF arrived attached to the order email but it took until the next morning, which is fine but slightly slower than a competitor that has a customer portal with auto-generated lot reports. Not a dealbreaker. Product itself is what counts and the product is right.
Good product, MS peak as expected
Mass spec showed expected molecular weight (4963 Da). Purity ran 98.7 on our HPLC, which is essentially identical to the supplier COA. Slight star deduction only because 22EXO ships in foam-only packaging, which I prefer over bubble wrap, but I think they should add a desiccant pack for thermolabile products like TB-500 even though stability data says lyophilized form is fine at ambient for short windows.
Convenient blend format
Pre-combined saves prep time.
best convenience product in their lineup
this is the kind of formulation move that tells me they actually talk to researchers. no other supplier sells this 4-way premix.
rare peptide, easy order
hard to find at this quality. 22EXO is now my supplier
Superior nootropic peptide
Highest purity and activity.
antioxidant standard
glutathione is a workhorse for oxidative stress assays. 22EXO's product is clean and at the right concentration.
good but reconstituting 500mg takes a bit
the volume is so large it takes a couple minutes to fully dissolve. small thing. quality is there.
oxytocin quality
behavioral neuroscience research uses oxytocin and theirs is high quality. coa shows 98.9 purity.
Generous 500mg format
Outstanding purity, competitive price.
did the job
what more do you want me to say
Better packaging than ___ (rhymes with peptide warehouse)
I won't name names but the prior vendor I used shipped these in zip baggies. 22EXO uses real cold packs and sealed boxes. Night and day.
saves hours per week
running multi-peptide protocols and not having to reconstitute three separate vials per session is worth the small premium they charge
good product, packaging was a little bent
vial was fine. box looked like it lost a fight. peptide reconstituted clean tho. 4 stars only because the box arrived crushed but contents were perfect so probably a fedex thing not them
exactly what i ordered
ordered tues, arrived friday. coa was right there in the box, purity 99.1. ran my own hplc in lab and it lined up. nothing more to say.
Consistent for immune-cognition work
Used in a series of T-cell maturation experiments. Activity has been consistent across the two lots we've ordered.
TA1 quality is up there
thymosin alpha 1 is studied in immune research. 22EXO's product is clean and well-documented. coa is detailed.
