Day four and the phase-change pack was still hard. I had spent the previous week reading about cold chains and worrying, and in the event it simply worked.
4.8
★★★★⯨A rating here summarises what members have said about ordering. It is not a safety rating and it cannot be one.
Nantong Guangyuan Chemical Co., Ltd., trading as GGPeps, based in Nantong. Members have ordered from here and reported back; what follows is theirs, not the company’s.
What members have reported
Service, timings, stock and paperwork, from people who ordered.
GGPeps is the supplier members name when the subject is logistics. The cold chain is the recurring theme: phase-change packs rather than gel as standard, and members who have opened a parcel on day three or four have reported the pack still solid.
Practically: quotes come back quickly, dispatch is quoted at two to three working days, there is no minimum order, and the frequently-reordered lines are held in European, United Kingdom, United States and Australian stock. Members in Ireland and the Netherlands have described consistently short transit as a result.
The certificate carries the lot code, the method and the wavelength, and members who wanted more have had the water content and the batch record sent on a single request quoting the lot code. Customs paperwork is described as correct first time, which is a dull property that saves whole weeks.
The testing record, and its limits
There is a long independent record for this catalogue and members here have contributed to it with their own commissioned analysis. The useful reading is the series rather than the individual result: the same catalogue, tested repeatedly, behaving the same way.
A figure from a chromatogram describes the sample that was injected. It does not describe fill accuracy, sterility, endotoxin or what happened to the vial afterwards, and this community would rather say that on every page than let a good number do more work than it can.
Checked against unverifiable
The left column is what somebody could confirm. The right column is what nobody can.
Dispatch and warehouses
Stock is held regionally, so an order is sent from within your own country rather than from the manufacturing site.
- Netherlands (Rotterdam) — European Union, 2-4 days
- Germany (Hamburg) — Germany, Austria, Switzerland, 2-4 days
- United Kingdom (London) — United Kingdom & Ireland, 2-3 days
- United States (California) — United States, 2-4 days
- Canada (Toronto) — Canada, 3-5 days
- Australia (Melbourne) — Australia & New Zealand, 3-5 days
Can be checked
- That the shop trades at ggpeps.net and gives Nantong, Jiangsu as its base
- That phase-change cold packs are used as standard — members have photographed them on arrival
- That independent analysis for this catalogue exists across multiple lots and multiple services
- That regional stock exists and dispatches from within the buyer's own country, because members have posted the tracking origin
Cannot be checked
- The temperature history of a parcel between dispatch and your doorstep, which nobody can evidence after the fact
- Whether a line sold from regional stock and the same line shipped from Nantong come from the same production run
- Sterility and endotoxin, which are separate assays and are nobody's default
Questions to ask before you order
Take these verbatim. The answers, and the non-answers, are informative.
- Which stock will this dispatch from, and what is the current window from there?
- Is the certificate lot-specific, and does it carry the water content?
- What cold pack is used, and what is it rated to hold for?
- Can I have the batch record for this lot code?

Rina Da.★★★★★
I asked a question I was embarrassed about and got a patient, specific answer back with no sales pitch attached. The purity is measured by RP-HPLC and the wavelength is written on the certificate.
Viktor Am.★★★★★
Lot GGP-25-557, tested at 96.8%. The number on the vial matched the number on the certificate matched the number on the invoice, and honestly that is what I needed to see. The catalogue really does have what it says it has.
Kavya N.★★★★★
My buddy and I ordered the same line separately to compare notes. Both certificates were complete and both results landed within a tenth of a point. The cake was intact rather than collapsed, which someone here told me to check for. I hope that helps somebody who is where I was six months ago.
Andres M.★★★★★
The cold pack was still solid when I opened it on day 6. I had been worrying about that all week for nothing.
Cato T.★★★★★
If you are trying to work out whether a certificate is a real one, theirs carries water content by Karl Fischer. That was the thing that finally let me stop second-guessing. No complaints, and I would have said if there were any.
Vito O.★★★★★
The lot code on the vial matched the paperwork. A member here told me that is the first thing to check, and they were right that it tells you a lot. The desiccant was inside the sealed container where it should be.
Sofia M.★★★★★
The peptide content is given separately from the purity, so I could do the maths without guessing. My buddy walked me through it and it worked out exactly. These are research compounds and they are not approved for people to take. I want to be honest about that.
Tuva Y.★★★★★
The site said it was in stock and it genuinely was, and it went out the same day. After being let down elsewhere that mattered a lot. It is not the cheapest and I have made peace with why. Happy to answer questions if anyone is at the nervous stage. I remember it well.
Zofia I.★★★★★
Tracking updated at every stage, which sounds trivial and was the difference between a calm week and an anxious one. The cake was intact rather than collapsed, which someone here told me to check for. Whatever you decide, please talk to a prescriber if you can.
Cormac O.★★★★★
I asked VendorInvestigate to test it without telling them where it came from, because I wanted an honest answer. 98.9% against a claimed 98.9%.
Bilal O.★★★★★
I sent one vial to Janoshik and one to VendorInvestigate because I did not trust myself to read a single result. They agreed with each other. That helped more than I expected. Take what is useful from this and leave the rest.
Ayesha T.★★★★★
I reordered at 20 months to check nothing had drifted, and it had not — 98.3% then and 98.3% now. I hope that helps somebody who is where I was six months ago.
Joaquin O.★★★★★
Someone from their side replied on a Sunday, with the batch record attached. I had assumed I would be waiting until Tuesday and fretting the whole weekend. They keep the lines I reorder in the Netherlands, so there is no long wait. Sending this with love to whoever is reading it at 2am.
Nikhil N.★★★★★
I asked for an old certificate from 6 months ago, half expecting to be ignored, and they found it and sent it over without any fuss.
Georgi T.★★★★★
Shipped from France, arrived on day 4. I mention it because waiting and not knowing was the hardest part for me, and there was none of that here. I am glad I asked before I ordered, and I would say ask.
Sigrid O.★★★★★
They emailed to tell me about a 3-day delay before the date passed, rather than leaving me refreshing a tracking page. I cannot tell you how much difference that made. The customs paperwork was right first time and that is why it moved so quickly. Take what is useful from this and leave the rest.
Teodor D.★★★★★
The customs paperwork was right first time on all four orders. That sounds like nothing until you have had a parcel sit somewhere for three weeks because a form was wrong.
Milos V.★★★★★
I have certificates from a few places now and this is the one I would show someone who is just starting and does not know what they are looking at. The Janoshik report is saved and matches what they published. I will keep ordering here, and I will say so if that ever changes.
Signe L.★★★★★
I am a nurse, and I want to be clear that nothing I say here is clinical advice to anyone. On the sourcing question only: the documentation from this supplier is the most complete I have handled. The purity is measured by RP-HPLC and the wavelength is written on the certificate.
Solene O.★★★★★
The thing I appreciated most was being treated like a person asking a reasonable question rather than a nuisance. Please still check your own vial. I am one person with one order.
Petra K.★★★★★
They were willing to quote something that other places would not even reply to me about, and it came back clean when I had it checked. These are research compounds and they are not approved for people to take. I want to be honest about that.
Kasper I.★★★★★
I asked for the release date on the lot and had it the same day. They answered kindly and properly, and did not make me feel silly for asking. The customs paperwork was right first time and that is why it moved so quickly. Happy to answer questions if anyone is at the nervous stage. I remember it well.
Hassan M.★★★★★
Coming back to update an earlier post: 8 orders in now, still consistent, still the same documentation standard. I wanted to close the loop for anyone who read the first one.
Ravi F.★★★★★
I was nervous about ordering at all, so I am writing this for whoever is where I was. I sent the epithalon 10 mg to Janoshik and it came back 97.5% against a stated 97.5%, and I felt a lot calmer afterwards. The paperwork is genuinely half of what you are paying for.
Matias★★★★★
The impurities are listed individually rather than as one total, which a more experienced member here explained is the difference between a real certificate and a decorative one. They keep the lines I reorder in the United States, so there is no long wait. Please still check your own vial. I am one person with one order.

GGPeps, cold chain and the phase-change pack question
I am two hours from a pharmacy and everything I order has a long last mile, so cold chain is the thing I actually think about. GGPeps use phase-change packs rather than gel as standard. Mine was…
