MDPiHP, chemically known as 3,4-Methylenedioxy-α-pyrrolidinohexiophenone, is a synthetic cathinone with psychoactive and stimulant properties. This compound is a derivative of pyrovalerone, sharing structural similarities with well-known substances like MDPV and α-PHP, which have been extensively studied for their effects on the central nervous system. MDPiHP’s action mechanism primarily involves the inhibition of dopamine and norepinephrine reuptake, leading to increased concentrations of these neurotransmitters in the synaptic cleft, thereby enhancing euphoria, alertness, and energy levels.
Effects and Experiences
Users have reported a range of effects from MDPiHP use, including but not limited to enhanced mood, increased energy and sociability, heightened sensory perception, and euphoria. These effects are similar to those reported for other synthetic cathinones, albeit with unique distinctions in their intensity and duration depending on dosage, individual physiology, and method of administration.
Dosage Guidelines
The appropriate dosage of MDPiHP varies significantly among individuals, and due to its relatively unknown profile, precise dosing recommendations are challenging to establish. Users have reported threshold effects with doses as low as 5 mg, with more common doses ranging between 10 to 30 mg. It is paramount to approach dosing with caution, starting with the lowest possible dose and gradually increasing to gauge individual tolerance and response.
Potential Side Effects
The use of MDPiHP is not without risks. Reported side effects include but are not limited to palpitations, anxiety, paranoia, insomnia, and in severe cases, psychotic episodes. The risk of dependency and the potential for abuse are significant concerns associated with its use. Long-term effects remain largely unknown, necessitating further research and caution.
Harm Reduction Practices
Given the potential for negative outcomes, adopting harm reduction practices is crucial. These include:
- Starting with the lowest possible dose to assess tolerance.
- Avoiding polydrug use, especially with substances that may have synergistic or unpredictable effects.
- Ensuring a safe environment and the presence of a sober companion during use.
- Staying hydrated and taking breaks to rest and recuperate.
- Seeking immediate medical attention in the event of adverse reactions or overdose.
In summary, MDPiHP is a potent research chemical with psychoactive and stimulant properties. While it offers insight into the pharmacodynamics and effects of synthetic cathinones, its use is fraught with potential risks. Caution, informed decision-making, and adherence to harm reduction practices are essential for individuals choosing to engage with this substance.

Attention
Products that are not available are offered.
I was once sent a cheap and ineffective substitute product without being asked, and with two additional orders, I was (oh how politely) offered a replacement for the product I wanted or promised delivery two months later—an impertinence and not customer service.
Furthermore, when ordering medication, only a fifth of the paid goods were sent…
Why offer things you don’t have? Is cheapness more important than creditworthiness?
Rechemco –
Thank you for your feedback.
We understand your frustration and are truly sorry for the inconvenience you’ve experienced. Our intention has never been to deceive or disappoint our customers.
Regarding the product availability: sometimes certain compounds require synthesis of a new batch, which can cause unforeseen delays. In such cases, we always offer either a replacement or a full refund to avoid keeping customers waiting indefinitely – as we did in your case. This is a standard and transparent policy we apply to ensure fairness.
We do our best to serve hundreds of customers every day, and while most are understanding, occasional delays or inventory issues can happen – especially with complex or custom products. Still, we always strive to make it right.
That said, we value constructive criticism that helps us improve. But accusations without context or understanding of the process don’t contribute meaningfully and are unfair to the efforts we put in daily.

1 Monat warte ich bereits, ein Replacement scheint ausgeschlossen, x mal vertröstet und geben an in 7 Werktagen zu liefern 🙁

Rechemco –
Sending repeated messages in large fonts, using colors, or posting negative reviews will not speed up the process — it only wastes time and creates unnecessary stress.
We are currently experiencing the same situation with other customers, which means this is a general delay and not specific to your order.
Normally, delivery takes around 10 working days, but unfortunately, this time it’s taking longer.
We sincerely apologize for the delay and appreciate your understanding.
benejichaser (verified owner) –
great compound, very pure and clean!
results of ‘in vitro’ tests indicate a strong reuptake inhibition, primarily on dopamine and norepinephrine. possibly some serotonergic activity as well but rather unsignificant.
tests were done in vitro by simulating various animal- aswell as human models.
safety protocols were implemented and followed with great care to assure total legal compliance.

I find this interesting because i ve been doing research with this chem under a long time and i ve seen the same type of reviews and same with the description but i have totaly different experiences and wonder if its only me and why? I ll explain and the difference is big. Ok:
Powerful and potent yes but i my findings no stimulating or up results it s more or very similar a extasy trip To me or for is the opposite, nothing on dopamin or noradrenalin, sorry nothing is the wrong word, enough to be clear headed but the main effects are seretongenic, i do not enjoy extasy because of the fast and all to high eufori rush and then a sudden nasty crush so on, this is exactly what happens with this compound, but i discovered another thing that suited me more than fine and the reason to which is one of the substances i ve used the longest. In low dose and added to a stimulant, especially a strong one, i don t know if i am allowed to give examples so i wont but when that? This chem creates a balance between all 3 …… i ve mentioned ok, dopamin, noradrenalin and seretonin, it balances it perfectly and the biggest reason for me at least, the effect of wichever compound it is, i only did research with stimulants and many many different types, if the effect let s say is 1 hour this is boosting that to 3 even 4 hours, so one can also image what it does to the ones with 4-8 hours initial effect. So i a strange why i first did not like it a nothing to end up in loveing it. After getting the dose ratio on the spot. So i am glad to see that it s here and i can t wait to see what!!!! Which is it gonna be, mine or everyone elses. Lol. I will post the results here for the ones that find this as interesting as i. Cause this is research at it s best. Thank you.

We received finally after almost 2 full months 🙂 shipped late december, arrived here yesterday. WOW!
Rechemco is a unit, he does right. But a slight critique i have to leave here: the MDPIHP was underweight and another chem overweight, i hope our friend dennis didnt switched things up here, could destroy our research-plans…. and my plants.
Normally id give 6 stars, but because of these 2 little things i have to stay with 4.
but i will be an backcoming customer!

Hello and thank you very much for your review and for your patience.
We truly appreciate your trust — especially during the November and December period, which was particularly unpredictable in terms of postal delays. We are sorry for the extended delivery time, and we understand how frustrating that can be. Fortunately, more and more customers are now receiving their shipments, and the backlog situation has been steadily improving.
Regarding the weight difference you mentioned: we always weigh and pack products carefully before dispatch. In some cases, slight variations can occur due to packaging differences or scale calibration sensitivity, but we do not switch substances, and every item is labeled and handled individually to avoid mix-ups. If you would like, you can contact support with details and we can look into it more closely.
Thank you again for your continued support — we look forward to assisting you with your next order.
Please remember that all products sold are Research Chemicals, not intended for human or animal consumption. Proper research safety procedures and a precise scale are required.

Hello and thank you for your review!
We appreciate your feedback and are glad to hear that your package finally arrived, even though the delivery took longer due to the Christmas period. Postal delays during that time affected many shipments, so we thank you for your patience.
Please remember that this is a very potent compound, so it’s important to conduct research carefully and handle it with proper precautions.

Firstly it took them 6 weeks to get this delivered by normal mail. Ordered in January. Secondly I asked them specifically if this was the hcl version, which they couldn’t answer.
Well it’s the hcl version, unable to smoke, vape and isn’t water soluble.
It’s also the same shitty batch as that was going around since February 2025 on most vendor websites. So save yourself some money and disappointment, just pick another better rc atm.
Rechemco –
Hello and thank you for your feedback.
First, regarding the delivery time: unfortunately, standard mail can sometimes take longer than expected due to postal delays, especially depending on the destination and seasonal workload.
About the product form: all stimulants we sell are in HCl form, which is the standard and most stable salt form for laboratory handling. If you had contacted us before the purchase, we would have clarified this for you directly.
Regarding the batch quality: this compound is one of our best-selling products, and we receive consistent positive feedback from many researchers. We also want to clarify that we have processed multiple different batches over time, so it is not possible that the material you received comes from a batch circulating since February 2025.
Different batches of the same compound can sometimes show slight variations in color, crystal structure, or texture due to synthesis and purification differences, while still being the same molecule and within expected specifications.
Thank you for sharing your opinion.

Well, I’ve been shopping at Rechemco for a while now; I’ve placed dozens of orders (Mr Dennis can confirm this) and today is the first time I’m going to take the time to leave a review for this shop because I’m reading the feedback on this product (which I find to be a wonderful stimulant – in fact, it’s the only one I take) and I’m reading some things that strike me as completely unbelievable. I’m not questioning the truth of these accounts, but reading certain cases and comparing them with my own long experience here as a customer is quite shocking to me.
I don’t want to drag this out, so I’ll try to summarise my case as concisely as possible in a few points:
1- I am an elderly European citizen who has been experimenting with RCs for fun for about 6 or 7 years.
2- I’ve placed orders with almost all the current suppliers, the ones everyone knows, and for the past couple of years, 90 per cent of the RCs I’ve bought have come from Rechemco.
3- From the very first time I placed an order here, I realised I’d found a special place. It wasn’t Dennis’s friendliness and approachability that caught my attention, nor the almost exact 10 days it usually takes for my orders to arrive, nor the extras I’ve received such as products or vouchers, nor the excellent advice this gentleman offers whenever you have a query – and you immediately realise you’re speaking to someone who really knows their stuff when it comes to our favourite subject. The fact is that after that first order and that first positive experience, it was clear to me that this chap (Dennis) – whoever you are – and I were going to build a solid, long-lasting business relationship. And that’s exactly how it turned out; I wasn’t wrong – here we are still going strong.
4- I’ve experienced some delays with my deliveries; we’ve had discussions (sometimes very serious ones) about his products and the different batches that might be available; we’ve talked about their quality. In short, over such a long period, we’ve covered it all… so I think I can put something on record… let’s list them:
a) The honesty of this laboratory and the person at its helm is beyond any doubt. To anyone who has doubts, I’d stake the life of one of my children on it, because Mr Dennis has been proving this to me WITH ACTIONS throughout this long journey since we first met.
b) Out of dozens of orders, I have NEVER, ever had to lament the loss or misplacement of any of them. ABSOLUTELY EVERYTHING I’ve paid for has arrived at my home.
c) I have had moments of doubt when an order took longer than usual, but I always followed Dennis’s advice, which was: ‘You just need to wait a little longer; your order will arrive.’ And indeed, shortly after that reassuring message, the order has ALWAYS arrived safely.
d) The only problem I’ve ever had was with an order for 5g of MDPiHP; surprisingly, the bag it was in didn’t withstand the journey, and some of the contents spilled into the inner reinforcement bag. I mentioned this to Dennis; I told him I wasn’t satisfied with the quality of the bags he was using to pack this product, and the subsequent deliveries arrived in perfect condition (with different, stronger, higher-quality bags).
e) I find Mr Dennis to be such an honest person that he knows where I live and who I am; I have even sent him photos of myself and my family so that he can get to know me, and I have offered him my home for a holiday should he ever happen to be in the area where I live (this is true; Dennis himself can confirm it).
And finally, the section:
f) This MDPiHP that he currently sells strikes me as the most comprehensive stimulant on every level that a psychonaut researcher can currently obtain (whether in the ‘Clear’ or ‘Deep’ form, whether alegal or illegal); for me, it is the best.
That’s all; warm regards, and there you have my experience and my opinions…
In my country, there’s a saying that goes: ‘Render unto Caesar what is Caesar’s’… which means that everyone should be given what is theirs, what they deserve – that is, a telling-off and punishment if they do wrong, or, conversely, recognition and gratitude if they do their job well (as is the case with this laboratory). That’s all.
Best regards.
Take care, everyone.
Rechemco –
Hello,
Wow… thank you so much for taking the time to write such a thoughtful and heartfelt review.
Reading feedback like yours truly means a lot to us. Over the years we’ve exchanged many messages, discussed products, batches, shipping delays, and many other topics. Building a relationship based on honesty, trust, and mutual respect has always been one of our main goals, so it is incredibly rewarding to know that this is exactly how you feel after all these years.
Thank you for pointing out something that many new customers may not realize: sometimes postal services are unpredictable, but in our experience, if the address is correct, the vast majority of letters eventually reach their destination. Patience is often the only solution.
We also appreciate your feedback about the packaging. Constructive criticism helps us improve, and as you noticed, we changed the packaging for MDPiHP after receiving comments like yours. We are always looking for ways to make our service better.
Most of all, thank you for your trust. The fact that you have chosen us for so many years, recommended us to others, and even shared a little part of your life with us is something we genuinely appreciate. Customers like you are the reason we continue doing what we do.
We will continue working hard to provide high-quality research materials, honest support, and the best service we can offer.
Thank you once again for being part of this journey. We wish you all the best, successful research, and many more years of collaboration.
Take care, and thank you for your incredible support! ❤️

I liked the batch from two years ago, so I decided to buy some more—but what a disappointment…
The product is really poor quality, and on top of that, it has become much more expensive…
It melts very poorly and leaves behind horrible residue…
Rechemco –
Hello, thank you for your feedback. We’re sorry to hear that you’re disappointed with this batch.
We have had several batches over time, and the current product is from the same batch that has been available since last year. Differences in research methods, temperature control, or the cleanliness of laboratory equipment may affect experimental results. However, we cannot determine the cause of the residue based on your description alone.
Please note that this is the last batch currently available on the market.
We appreciate you sharing your experience and encourage you to conduct research carefully, follow appropriate laboratory procedures, and use clean, suitable equipment.
Important: All products sold are Research Chemicals, not intended for human or animal consumption. Always handle them responsibly, use appropriate laboratory safety procedures, and never underestimate the potential risks of these compounds.
