ERP — member reviews

Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.

4 lots logged now, purity 98.6 to 98.9%. A band that tight is worth more to me than one spectacular number.

Eighth order from them, all KPV 10 mg. Sent one vial from each to PeptideMeter and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.

Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.

Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.

Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.

First order, deliberately small, semax 10 mg only. Documentation, transit and a PeptideMeter result at 98.6% all checked out, so the next one will not be small.

One of the few places that will quote GHK-Cu 50 mg at all, and the synthesis came back clean on an independent check.

Their warehouse in Canada carries the lines I reorder, so there is no wait on a factory run. Day 3 every time.

Regional stock makes the difference — dispatched within Canada, day 4, cold pack still hard on arrival.

Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.

The certificate for lot ERP-26-301 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.

Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.

Arrived on day 3 against a quoted 3. Customs paperwork was right first time, which is why it moved that fast.

Submitted the semax 10 mg to Janoshik blind, without telling them the source. 99.4% against a stated 99.0%. The number holds up when nobody knows whose vial it is.

The semax 10 mg arrived on day 2 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.

Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 3 hours.

Reconstituted the tirzepatide 15 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.

Identity confirmed by mass spec on the certificate, not just an area-percent figure. Both questions answered on one page.

Reordered on the strength of the last one and got an identical result. Repeatability is the product.

Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.

Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.

They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.

Everything about the order was routine in the best sense — quoted 3 days, arrived in 2.

Cold pack was still hard on arrival in Rotterdam on day 4. My logger never went above 7°C across the whole run.

Domestic dispatch from their stock in Canada. Straightforward, day 2, exactly as quoted.
