Authentic copper peptide

Color is right, mass spec is right, reconstitution is clean. Will reorder.

Triple blend convenience

Three peptides pre-blended at the published research ratios. Saves substantial bench time on multi-arm work.

Verified

consistent across lots

third order, third clean lot. cell migration assays line up with what we got from the previous batches.

Verified

OXTR receptor work

Du Vigneaud's nine-residue peptide synthesized cleanly here. Disulfide bridge intact by mass spec. Good reagent.

NAD+ substrate quality

Useful for sirtuin activity assays. Quality matches what we used to source from a more expensive supplier.

Verified

LR3 modification stable

Long Arg-3 modification — stable in our cell culture. Published growth factor signaling reproduces well.

MC1R work

Cyclic structure looks right by mass spec. Some lot variation in solubility but workable.

Native GHRH(1-29) reference

Good as a pharmacokinetic reference compound. Sequence-authentic. Half-life matched published values.

10mg vials better value

10mg vials for lab use are more practical than 5mg when running multi-arm protocols. quality matches.

Skin tissue work

Pickart's published sequence. Consistent product across two purchases. Recommend.

Niche but useful

DSIP is hard to source at this purity. Glad to have a reliable supplier. Slow delivery, otherwise good.

Combo blend, even mix

Visual inspection shows even lyophilizate. Reconstitutes cleanly. Tendon healing model running well.

Verified

Classic GH secretagogue, clean

GHRP-6 from a quality vendor is hard to find consistently. This was clean. Same-day appetite signaling effect we expect from this molecule.

lipolysis assay clean

fragment 176-191 with the tyrosine cap. ran cleanly on hplc. lipolysis curves looked right.

GnRH-axis activation reproduces

Standard kisspeptin-10 LH response curves match published data. Good reagent for hypothalamic work.

Dr. P. Schmidt

Solid product

MC4R receptor work — produced expected dose-response. Slight color variation between lots, possibly normal.

C. Romero

T-cell maturation assay reagent

Reliable T-cell differentiation effect in our culture system. Consistent across two lots so far.

June 13, 2026
Verified

Visceral adipose model work

We are running this against published Theratechnologies data. The lot performs in spec.

Dr. F. Chang

Verified

Pre-blended saves time

Pre-blended saves us a reconstitution step. Ratio matches the standard 2:1 protocol.

Verified

Authentic Khavinson tetrapeptide

Good replication of published telomerase activity data in fibroblast lines. Sequence verified.

June 10, 2026
Verified

clean pulse stimulation

GH pulse in our model came up cleanly with this lot. no complaints.

Mitochondrial signaling work

Activated AMPK as expected in muscle cell line. Solid reagent.

Good but slow shipping

Product is fine. Shipping took longer than the last order. Vials intact.

T. Hoffmann

Verified

Consistent purity batch over batch

Third order. HPLC checks have all come back clean. Stable lyophilizate, no caking.

blue tint right where it should be

looks like ghk-cu should look. fluorescence assay results were in expected range. happy.

Reliable for actin migration assays

Reproducible chemotaxis curves across three replicates. COA matched the lot.

Telomerase research supply

Epithalon at 10mg is the sweet spot for our chronic-dose protocols. Quality has been consistent.

PT-141 received

purity ran 98.7 on our qc. matched their coa. shipped fast.

Stack at 10mg is the value play

10mg blend at this price point is cheaper than buying separately. Activity matches expected combined response.

Verified

triple-blend works

convenience product. saves two reconstitutions per session. quality is fine.

Verified

ipa quality matches the bigger names at a better price

compared to two of the bigger established suppliers, 22EXO ipamorelin is indistinguishable in our lab QC tests. price is meaningfully better.

May 26, 2026

tesamorelin at fair price

tesamorelin has been an expensive peptide to source clean. their pricing and quality are both good.

Reliable across lots

Five lots ordered. Five clean COAs. Five passing internal QCs. That's the metric that matters.

Hard-to-source, theirs is good

MOTS-c is not easy to find at this purity. theirs runs clean on our qc.

TA1 for T-cell maturation work

Thymosin Alpha 1 is a workhorse for our immune research. 22EXO's preparation has been consistent.

May 21, 2026
Verified

Good product, would like a 10mg option

TB-500 quality is excellent. Only feedback: a 10mg vial size would let us run larger arms without reconstituting two 5mg vials per session.
