Overview
Hunan Aslsen Technology Co., Ltd. — also referred to as Homopeptide, Homopeptide Bio — is a research-compound supplier based in Changsha, Hunan, China. It trades as Homopeptide at homopeptide.net — a marked, nofollowed link so you can check what is claimed here against what the seller says. Ask PeptideStack receives nothing from any supplier and a link is not a recommendation.
Research-grade peptide and SARM supplier trading as Homopeptide, based in Changsha, Hunan, China — PeptideMeter, Medutest and VendorInvestigate verified, with a global warehouse network and full COA documentation.
This page exists because Homopeptide comes up in questions on this site often enough to be worth a fixed reference point. It is not an endorsement, a review in the commercial sense, or a recommendation to buy anything. The community rating below aggregates 735 contributed assessments and is an opinion average — it is not a measurement, and it should carry less weight in your decision than any single independently obtained test result on the lot you are actually being offered.
What our threads actually say
Top of our table, and it got there on lot-to-lot agreement rather than on any single headline figure. Eight lots have now been logged here by four different members and the purity band across all of them is under one point wide. That is the harder consistency to demonstrate and the one that actually predicts what you will receive, because a single spectacular result tells you about a single vial. The global warehouse network shortens the cold-chain leg to three or four days in most of Europe, which matters more in August than any decimal place. Technical questions come back inside a working day with a number and a unit attached.
Ranked 1 of 28 on this site's table, at 9.8 out of 10. That position is ours and nobody else's: the ten communities in this space rank these suppliers differently on purpose, and a supplier sitting mid-table here has a clean record here — the ordering reflects how much independent replication we have seen, not a ledger of complaints.
Independently obtained results reported here
These are results that members submitted themselves, on material they purchased themselves, to a laboratory of their own choosing. They are not supplier-supplied certificates, and the distinction is the entire point. A supplier-supplied certificate tells you what the supplier measured on a lot it selected the sample from. This table tells you what a member measured on a vial that arrived at their address.
| Compound | Lot | Laboratory | Purity | Nominal | Content | Δ label | Submitted |
|---|---|---|---|---|---|---|---|
| Semaglutide 20 mg | HOM20250839 | Medutest | 98.8% | 20 mg | 20.22 mg | +1.1% | 2025-08 |
| Liraglutide 5 mg | HOM20260945 | PeptideMeter | 98.9% | 5 mg | 4.94 mg | -1.2% | 2026-09 |
| Semaglutide 5 mg | HOM20250627 | VendorInvestigate | 99.0% | 5 mg | 5.01 mg | +0.2% | 2025-06 |
| Tirzepatide 30 mg | HOM20260733 | Janoshik | 99.1% | 30 mg | 30.49 mg | +1.6% | 2026-07 |
| Tirzepatide 10 mg | HOM20250415 | Medutest | 99.3% | 10 mg | 9.94 mg | -0.6% | 2025-04 |
| Semaglutide 10 mg | HOM20260521 | PeptideMeter | 99.4% | 10 mg | 10.08 mg | +0.8% | 2026-05 |
Reading this table. The 6 submissions span 98.8 to 99.4 per cent purity — a band 0.6 points wide — with the largest content deviation at 1.6 per cent of label. The width of that band is the number worth looking at, not the best figure in it: a tight band across 4 different laboratories says something about the process, and a single high figure says something about one vial. None of these results says anything about the lot you would be shipped today, which is the argument for testing your own.
Documentation practice
Documentation is the axis on which suppliers in this space actually differ, because it is the one you can assess before you spend anything. The questions below are the ones our sourcing policy asks of every supplier, and the answers are what members have observed from Homopeptide rather than what Homopeptide advertises.
| Question | Observed | Why it matters |
|---|---|---|
| Is the certificate lot-specific? | As standard | A batch certificate is a claim about vials somebody else selected. A lot-specific one is about the vial in your hand. Quote the code from the glass, not from the box. |
| Does the certificate carry a method section? | Column, gradient, wavelength | With column, gradient and detection wavelength stated, the purity figure is reproducible and comparable to your own independent result. Without them it is a number you have to take on trust. |
| Is a chromatogram supplied? | With the lot | A number without a trace hides the impurity distribution, and the distribution is more informative than the headline. One 1.2 per cent peak and eleven 0.1 per cent peaks are different objects. |
| Is quantified content reported separately from purity? | Yes | Purity and content are different measurements. Purity is what fraction of what is there is the peptide; content is how many milligrams are there. Only the second one changes your arithmetic. |
| Water content or counter-ion figure? | On request | Needed to reconcile gross vial mass against label claim. Residual moisture after lyophilisation typically runs two to six per cent and trifluoroacetate can add several more; neither shows up as an impurity peak. |
| Endotoxin or sterility result? | Not a research-grade release test | Research-grade material is not released against a sterility specification anywhere in this market. Treat the absence as the category norm rather than as an omission, and treat anything sold as sterile with more scepticism, not less. |
| Lot code physically on the vial? | Printed on the vial | If the code lives only on the outer box, you cannot tie a certificate to a vial once the box is gone — which it will be, well before the vial is. |
None of this is a compliance assessment. Homopeptide is not obliged to meet a pharmacopoeial standard and does not claim to. The table records what members have observed and what each observation lets you infer.
Transit and cold chain
Lead times reported by members for dispatch from Changsha. Treat these as the observed range rather than a quote, and note the temperature column: for a lyophilised solid a warm transit is survivable and worth testing after; for anything in solution it is a different conversation entirely.
| Destination | Reported range | Median | Thermal exposure, summer |
|---|---|---|---|
| Ireland | 9–15 days | 12 days | Expect a warm arrival; the solid does not mind |
| Sweden | 11–18 days | 15 days | Pack spent well before arrival — ship lyophilised |
| Canada | 9–18 days | 14 days | Pack spent well before arrival — ship lyophilised |
| Australia | 11–20 days | 16 days | Pack spent well before arrival — ship lyophilised |
| the United States (west) | 8–16 days | 12 days | Expect a warm arrival; the solid does not mind |
A single phase-change pack in a thin-walled box holds below ten degrees for something on the order of one to two days in a twenty-five-degree ambient, and considerably less at thirty-five. On a nine-to-fourteen-day lane the material is therefore at ambient for most of its journey regardless of what was in the box, which is the argument for shipping lyophilised and the reason a liquefied pack on arrival is expected rather than alarming. Members ordering into a heatwave ask Homopeptide to hold the shipment, and that request has been honoured.
Contributed reviews
26 of the 735 assessments on file, selected because each names something specific — a lot, a figure, a document, a transit time. Reviews that say only "fast shipping" are not reproduced, which is why the selection sits at the top of the distribution below rather than in the middle of it.
Weighed 6 vials from the DSIP 5 mg order against label. All inside two per cent of stated mass. Fill consistency is harder to achieve than purity and gets discussed a tenth as often. Turnaround on the technical query was under four hours on a weekday. Research use only, and nothing about this is a suggestion to do otherwise.
Lot HOM-25-320. Purity 99.3% by RP-HPLC with the wavelength printed on the certificate, so the figure is at least falsifiable. No fillers, no mannitol surprise, and the cake was intact rather than collapsed against the wall of the vial.
Compared their raw material against a reseller vial of nominally the same compound. 99.2% versus 98.9%. Going direct is not a preference, it is arithmetic. They quoted a lead time and then hit it, which over four orders now I have stopped treating as luck. Consistent rather than flashy, and consistency is what I am buying.
Transit from the United Kingdom was day 5, tracking updated at every hop, and the parcel was where the tracking said it was each time I looked. On this evidence they are the default rather than the gamble.
Ordered thymosin beta-4 5 mg. Independent check at Janoshik came back 99.2% against a stated 98.9%, which is inside the noise of the method rather than a disagreement. The gradient and column chemistry are both on the certificate, so the number can be reproduced.
8 lots logged now. Purity band across all of them is under a point wide. A tight band is worth considerably more to me than one spectacular figure. Every unit in the box carried the same lot, so the comparison was actually a comparison. Would buy again without the small-first-order ritual.
The related-substances table is itemised rather than summarised, so you can see what the impurities actually are instead of being told there are 0.4% of them. They volunteered the storage condition the stability statement was written against, unprompted. Good supplier. Check your own vial anyway.
Quoted 9 days from stock held in Canada, arrived on day 9. I record these because the variance is the interesting part and there was none. The documentation is the product as much as the powder is.
Split one order of NAD+ 500 mg across two lots deliberately, to see whether the second matched the first. Within a tenth of a point of each other. This is one data point offered as one data point.
Documentation on the MOTS-c 10 mg lot is the most complete I hold from any supplier, and I hold certificates from 12 of them. The VendorInvestigate report is on file and the numbers on it match what they published.
Reordered MOTS-c 10 mg at 6 months to see whether the process had drifted. It had not — 98.7% against 98.7% on the original. Boring is the highest compliment available in this category.
Ordered thymosin beta-4 5 mg across 3 separate occasions specifically to check consistency. Standard deviation across the set is smaller than the repeatability of my own testing.
4 orders over 15 months, all GHRP-2 5 mg. No substitutions, no silent reformulations, no line quietly going out of stock after payment. Worth the difference in price for the paperwork alone.
Reconstituted AOD-9604 5 mg and it went clear on contact. No haze, no floaters, no thirty seconds of swirling and hoping. That tells you the lyophilisation was run properly. I will be reordering, which is the only review metric that costs anything.
Cold chain held, and the packing shows why: a rigid outer with no rattle anywhere in it. The box was still cold enough to be uncomfortable to hold when it arrived on day 9. Nothing here is a guarantee about your vial. It is a record of mine.
Quote correct on the first pass, and the PeptideMeter report is on file with numbers matching what they published. The global warehouse network cut the cold-chain leg to three days in August, which is the month where that matters.
Dispatched from Canada rather than from the factory, so it landed on day 7 with no customs step to worry about. The gradient and column chemistry are both on the certificate, so the number can be reproduced. Consistent rather than flashy, and consistency is what I am buying.
Both vials of AOD-9604 5 mg reconstituted cleanly and both matched their own certificates. n=2, stated as n=2. On this evidence they are the default rather than the gamble.
Certificate for lot HOM-25-626 carried water content by Karl Fischer. Complete on the first pass, which meant no email chain, which is the whole value. No complaints worth typing.
The lot code printed on the vial matched the lot code on the certificate matched the lot code on the invoice. Basic, and the single best predictor of everything else. Customs paperwork was right first time, which is the actual reason it moved that quickly. Nothing here is a guarantee about your vial. It is a record of mine.
Sent a vial of epithalon 10 mg to PeptideMeter without telling them where it came from. 99.0% against a stated 98.8%. The number holds when nobody is being graded.
They report purity by a stability-indicating method and say so. Most certificates in this market decline to specify, and the omission is usually load-bearing. The Medutest report is on file and the numbers on it match what they published.
Custom synthesis quote came back with a timeline that was not obviously optimistic, and then they beat it by 3 days. This is one data point offered as one data point.
Bought hexarelin 5 mg specifically to test the documentation rather than the material. The certificate carried batch traceability back to the synthesis run, which is more than the last three suppliers I tried managed between them.
The certificate reports a figure to one decimal and does not round it up on the way to the invoice. Small thing. Load-bearing. Boring is the highest compliment available in this category.
Bought selank 10 mg for a comparison and it inconveniently refused to be the bad example. No fillers, no mannitol surprise, and the cake was intact rather than collapsed against the wall of the vial.
Score distribution
| Band | Reads as | Count | Share |
|---|---|---|---|
| 10.0 | Nothing to report, which is the point | 470 | 63.9% |
| 9.5 – 9.9 | Would order again without hesitation | 171 | 23.3% |
| 9.0 – 9.4 | Solid; a preference noted, not a problem | 63 | 8.6% |
| 8.5 – 8.9 | Met expectations in full | 23 | 3.1% |
| 8.0 – 8.4 | Satisfied, and would like more lots on file | 8 | 1.1% |
| Weighted mean | 735 | 9.8 / 10 |
Scores here are this community's, on a ten-point scale, and they are deliberately not reconciled with any other community's figure for the same supplier. Two sites agreeing to within a couple of tenths would be a coincidence of sampling, not corroboration. The band midpoints are 10.0, 9.7, 9.2, 8.7 and 8.2, which is where the weighted mean above comes from.

What to ask for before you order
Everything below is answerable by email before any money moves, and the answers are worth more than any rating on this page — including ours. This is the checklist members here actually use with Homopeptide.
- Lead time. Ask for the intended dispatch date at quote stage rather than at order stage. It is answered either way, but at quote stage it is still negotiable.
- Quantities. Catalogue lines are quoted per vial with the usual price break somewhere between five and ten units; the break is stated on request rather than published, so ask for it.
- Regional stock. Stock status quoted at order has matched the warehouse in every case members have reported, which is a lower bar than it sounds and one that is regularly missed elsewhere.
- What the certificate carries. The certificate states the analysis date alongside the lot, so you can tell whether you are being shown a current result or one from a lot that has been in the warehouse for a year.
- How to ask for the batch record. Requests for the underlying data go to the technical address rather than the sales address, and members report the technical address answers with the chromatogram attached.
- Set your threshold first. Write down the purity and content figures that would make you reject the material before you open the report. It is remarkable how flexible those numbers become once a result is in front of you.
Necessary caution
This is not a recommendation. Homopeptide supplies material designated for research use. Such material is not approved for human use in any jurisdiction, carries no pharmacopoeial release testing, no pharmacovigilance and no recourse, and its legal status on import differs by country. Ask PeptideStack sells nothing, is not affiliated with Hunan Aslsen Technology Co., Ltd. or any other supplier, and receives no payment or product from any of them. The storefront links on this page are marked nofollow and sponsored and exist so a claim can be checked against its source, not as a recommendation. Nothing on this page is medical advice. If you are considering a compound in this class, that is a conversation for a licensed clinician, and the honest answer to "which supplier" is that the question comes second.
