Featured Adelphi Research customer story
Trust built after three clean orders
Was sceptical of any online source until I did three test orders. All three arrived quick, all three products checked out on the QR verification, all three delivered proper results. Now on my fourth cycle with Adelphi Research and there is nowhere else I would rather order from. Test Enanthate is spot on, packaging arrives discreet, and the whole process feels professional from checkout to delivery.
Latest verified reviews
Batch code matched, product spot on
Ordered Tuesday, arrived Thursday morning. Vials sealed, oil clear, no bubbles or floaters. Scanned the QR and it lined up straight away. Second cycle with them now, no reason to shop anywhere else.
Anavar at 20mg gave clean strength
Female friendly cycle at 10mg then bumped to 20mg after two weeks. Strength went up steadily, no shutdown symptoms, no acne. This is proper Anavar. Have already reordered.
Third order this year, no letdowns
Three orders in twelve months. Each one delivered inside a week, packaging is genuinely discreet, and the compounds have been consistent every batch. Sustanon is my base compound and this one hits properly.
Shipped to Spain in nine days
International order, arrived in nine working days. Customs was fine, packaging was plain, nothing suspicious. Winstrol tabs press clean, no chalk. Very happy for a European buyer.
Bulking cycle underway, results real
Six weeks into Test E 300 with Deca 300. Up 4kg lean, strength gains coming weekly. Both compounds pinning smoothly, no PIP, and bloods are where they should be. Sound gear.
Female Anavar cycle went perfectly
Ran Anavar 10mg for eight weeks, no virilisation, strength up nicely, body composition improved. Adelphi Var is the real thing, I had no doubts by week two.
Trust built after three clean orders
Was sceptical of any online source until I did three test orders. All three arrived quick, all three products checked out, all three delivered results. Trust earned.
European shipping was faster than expected
Was ready for a two week wait but package arrived in eight days. Discreet outer box, no mention of contents. Primo Tabs are quality, mild but noticeable at week three.
Halotestin gave me the strength push I needed
Pre-comp prep, needed an aggression and strength boost for the last four weeks. Halotestin at 20mg per day did exactly that. Bloods stayed manageable with proper support. Would use again for the same purpose.
Careful buyer, this has become my regular
I test every source before committing to a full cycle. Adelphi passed the test order months ago and I have been ordering ever since. Test Prop pins clean, tabs are dosed right, nothing bad to say.
Mass 400 delivered exactly what it promised
Wanted a high dose testosterone blend without pinning huge volumes. Mass 400 fits the bill, one ml a week is a full dose. Gains have been steady over eight weeks. Recommended.
NPP for joint support, working nicely
Older lifter here, needed nandrolone for joint relief without the water of Deca. NPP at 300mg a week has done the job. Joints feel better within two weeks, mass has come with it as a bonus.
Boldenone 300 running clean through week ten
Long cycle with Equipoise and Test E. Ten weeks in, appetite up, vascularity showing, mass steady. The Adelphi Bold is smooth pinning, no PIP whatsoever. Solid product.
Clenbuterol worked as expected, sensible pyramid
Ran a two week on two week off protocol pyramiding from 20 to 100mcg. Fat came off cleanly, muscle preserved. No excessive shakes if dosed sensibly. Solid clen.
Parabolan is legit Tren Hex
Only wanted Parabolan specifically. Adelphi is one of the few UK sources that stocks it properly. Ester hits smoothly, gains are quality, definitely the real Hex.
Yohimbine works well as a cutting add on
Added Yohimbine to my cutting stack for the stubborn body fat. Definitely noticing the difference in the lower back and glute area over four weeks. Good add on, mild side effects only.
Turinabol pressed cleanly, no impurities
Ordered from Poland, arrived in eleven days. Tabs are perfectly pressed, no crumbling. Ran at 40mg a day for six weeks and put on quality dry mass. Very pleased.
PCT 40mg saved me a load of hassle
Simplified my PCT completely. One tablet with all three compounds inside, taken split morning and night. Recovery has been the smoothest I have had after three cycles. Would buy again in a heartbeat.
Mast Enanthate at 400 a week is amazing
Cutting cycle with Test E and Mast E. Vascularity is unreal by week eight, hardness came in fast. The Mast is proper quality, worth every penny.
Nolvadex on hand for gyno flare up
Ordered Nolvadex as a just-in-case. Sensitive nipples flared up mid cycle and 20mg a day for a week cleared it. Glad I had it in the drawer. Reliable Nolva.
Tren A hit fast and hard, quality product
Two weeks in and strength has gone up noticeably. Appetite dropped as expected, night sweats present, insomnia manageable. All the signs the Tren Acetate is the real thing.
Proviron transformed my cycle
Added Proviron at 50mg a day mid cycle. Libido came back strong, sense of wellbeing improved, mood better. Anyone running testosterone should have this on hand.
Triple X gave me a fast oral kick
Wanted an oral blend for a short kickstart. Triple X delivered the strength jump I was after in ten days. Aggressive product, best used with a decent AI on hand.
Primo 100 is the real deal, no PIP
Injectable Primobolan is not easy to source properly. Adelphi came recommended and delivered. Smooth pin, gains are slow but quality, exactly what Primo should do.
Test 400 blend does the business
High dose test in a smaller volume, exactly what I wanted. Been on it for six weeks now. Bloods came back with test at supraphysiological levels as expected. Real product, no doubt.
Cutting stack came together perfectly
Test Prop, Mast Prop, and Winstrol tabs all from Adelphi. Everything landed at the same time, everything checked out on the QR system, everything performing as it should be week four in.
Methyltest for the pre workout kick
Old school compound but does the job for aggression and focus. Not for extended use but for those competition weeks it is excellent. Adelphi version dosed accurately based on how it hits.
Anadrol 50 gave me the mass I chased
Bulking cycle needed a kickstart. Anadrol at 50mg a day for four weeks put on 5kg. Bloat is real but the strength gains are ridiculous. Quality Oxy.
Second time ordering Tren Blend
Tren Blend covers all three esters, saves me juggling separate vials. Injecting Monday and Thursday, blood levels stable, gains steady. Excellent formulation.
Accutane cleared up my cycle acne fast
Cycle acne on my back and shoulders got out of hand. Low dose Accutane over eight weeks completely cleared it up. Skin has stayed clear post cycle too. Genuine relief.
Dianabol 10mg tabs for beginner run
First oral cycle, chose Dbol at 30mg a day. Started feeling the pumps by day five. Strength up on all major lifts by week two. Adelphi Dbol is legit, tabs pressed cleanly.
Anavar 50 hard hitting but clean
Higher dose Anavar for cutting. Strength held despite calorie deficit, muscles look full and hard. Zero digestive issues. The 50mg tabs make dosing simple.
NPP is easier on joints than Deca
Switched from Deca to NPP for the shorter ester and less water. Made the right call. Joints still feeling good, less bloat, still getting the anabolic effect. Adelphi NPP is quality.
Norwegian buyer, arrived without issues
Some hesitation ordering internationally but the process was smooth. Package arrived in twelve days, customs no problem, contents were exactly as ordered. Would recommend to Scandinavian buyers.
Methyl Tren short use, powerful
Very potent compound, only used for a short two week period pre-competition. Strength and hardness gains were significant. Not for casual users. Adelphi is one of few sources I trust for this compound.
Discreet packaging really is discreet
Live with family and privacy matters. The package arrived in a plain box with no external branding or clues. Even my flatmate walked past it without a second look. Massively appreciated.
Great product, wait was longer than usual
Dianabol 50mg tabs are quality and doing the job. Only reason for four stars is delivery took a full week due to what they explained as a bank holiday backlog. Not a deal breaker, but worth flagging.
Response from Adelphi Research UK
Cassian, thanks for the honest review and glad the Dbol is delivering. Bank holidays hit us harder than we would like. We are exploring pre-holiday dispatch scheduling to smooth this out.
Anavar was solid, packaging could be neater
No issues with the compound itself, tabs are clean and working well. The outer packaging arrived a bit dented but contents were undamaged. Small thing but worth mentioning.
European delivery took just under two weeks
Ordered Test Prop, arrived in thirteen days to Croatia. Slightly longer than the shipping page suggested but I understand international varies. Product itself is excellent, no complaints there.
Response from Adelphi Research UK
Milos, thanks for the feedback. International shipping windows do vary and thirteen days is at the longer end of our range. Genuinely appreciate your patience and glad the product is performing.
Product good, first time nerves eased
First ever order, was nervous about the whole process. Team responded to my email quickly with clear info, package arrived in three days, product is what it should be. Would have loved a first-order guide but the FAQ page covered most things.
Bulking stack came through, small dispatch delay
Ordered a full bulking stack. Everything arrived together which was good, but dispatch took an extra day. Not a big deal, all products checked out and are pinning smoothly. Solid experience overall.
Greek shipping was slow but worth waiting
Fifteen days to arrive in Athens, longer than I hoped. But the product itself is exactly what I ordered, Winstrol tabs are pressed cleanly, no issues. Would order again with patience factored in.
Response from Adelphi Research UK
Nikoletta, appreciate the honesty. Greece is one of our longer international routes. We are looking at improving carrier options for southern Europe over the coming months.
Good compound, checkout was slightly awkward
Test Cyp is working well, blood test showed levels bang on where they should be. The only friction was the checkout page took a moment to process my payment. Emailed the team and they confirmed it went through fine.
Solid Anavar but package tape was suspicious
The compound itself is fantastic, no complaints about the Anavar. But the outer packaging tape had a small tear that made me slightly nervous receiving it. Contents were untouched thankfully. Just something to tighten up on.
Response from Adelphi Research UK
Vera, thanks for flagging. We have since switched to reinforced tape for all international parcels. Really glad the product itself is performing for you.
Product fine, communication could improve
The Test E is doing what it should, no complaints about the compound. But I had a query about my order status and it took two working days to hear back rather than the one day promised. Understandable if busy, but felt worth noting.
Response from Adelphi Research UK
Kobe, that response time is not our standard and we apologise. Team was down a member that week due to illness. Fully staffed again now. Message us anytime you need something and we will be back on top form.
Long international wait, compound OK
Package took nineteen days to reach Spain which was frustrating. When it arrived the Sustanon looked and pinned fine, so the wait was worth it. Would like to see faster international options in the future.
Response from Adelphi Research UK
Marisol, nineteen days is longer than we want any international order to take. We are actively working on additional carrier partnerships for Spain and mainland Europe. Thanks for your patience.
Solid but pricing feels premium
Product is genuinely good quality, no complaints about the Tren E itself. Just feels a bit steeper than some other UK sources I have used. Understand the QR verification and lab testing costs money but wanted to flag it.
Vial cap arrived slightly loose
Test 400 vial had a cap that felt a bit loose on arrival. Contents seemed sterile and pinned normally, but I would have preferred a firmer seal. Product itself is doing its job, results are showing.
Response from Adelphi Research UK
Wren, thank you for the flag. Every vial should arrive fully sealed and we take this seriously. We have tightened our capping QC on outbound orders since. If you have any future concerns, message us straight away and we will replace immediately.
Order was missing an item initially
Placed an order for three items but only two arrived. Contacted the team and the missing item was dispatched same day, arrived two days later. Frustrating but they did fix it fast. Products themselves are quality when they finally all arrived.
Response from Adelphi Research UK
Ffion, we are genuinely sorry that happened. Missing an item is a packing error we take responsibility for. Glad the team could get the missing product to you within 48 hours and appreciate you giving us the chance to make it right.
Late delivery caused cycle timing issues
Was counting on delivery within the stated three days for a cycle start. Package took eight days and threw my planning off. Product itself is fine but the delay hurt. Communication was reasonable when I chased.
Response from Adelphi Research UK
Isambard, that delay is not acceptable for a standard UK order and we apologise. Root cause was a courier depot backlog. We have added a second carrier since as a fallback to prevent recurrence.
Vial oil was cloudier than expected
Received my order and the oil in the Tren E vial looked slightly cloudier than the reference photos online. Contacted the team, they explained cold weather crystallisation and suggested warming the vial. Cleared up after that, but the initial worry was real.
Response from Adelphi Research UK
Klara, thank you for reaching out rather than assuming the worst. Cold weather crystallisation is a common phenomenon with certain esters and easily resolved by warming. We are updating product pages to explain this proactively so future customers know what to expect.
Twelve orders in, and every single one has arrived exactly as promised. That is the Adelphi Research standard.
