Purchased a “Pam”chemical for research… Purchased a “Pam”chemical for research and received my order fast.I plan on making another purchase to compare chemical reactions,The solution isn’t the strongest so it took some trial and larger amounts then other company’s chemicals but it could have just been the batch.I only wish he offered powder substance chemicals for sale as well so it would be easier to test with the right amount. I will update review after trying other products.

These guys only pedal inactive and watered down products I received my first order and both bottles of two different items were completely inactive. They sent a replacement that had the same batch number and was from the same inactive batch. I thought maybe this was a fluke so I tried to order from them again. I spoke to customer service who said they were making a new batch that would be active. Well I received this next order and again both bottles inactive. They sent a replacement again but for a different product as I thought maybe it was just those two products that were inactive. I was wrong this bottle is completely inactive. I have talked to customer support numerous times and even let them know I would be posting reviews and they still continued to send inactive items. I am so very displeased with this company and their products. I might have just as well burned over 200 dollars in a fire because I got burnt by this company bad.

Long time customer Long time customer I have been using P4S for years. Top notch customer service and communication. Have enjoyed their variety of products over the years, have seen some come and go. For the most part quality has been highly consistent. Some batches have been 'better' than others, yes, but overall my research results have been solid. For ease of use and consistency, these guys are as good as it gets.

Was Nervous, Got Exactly What I Ordered. got exactly what i ordered. they’re closed over the weekend so id reccomend ordering on a monday-tuesday and it should arrive the same week. 10/10 communication 10/10 quality plus speedy delivery. will have my business again.

I guess I was wrong 🤷‍♂️ *update* package was received yesterday. 4 days after I ordered. Shipping time was quick. I’m giving 4 stars for the initial lack of communication. He said he doesn’t respond to messages or process orders on the weekends. A disclaimer somewhere stating that would probably be smart. All in all I would probably order again. *update* they just got back to me saying it’s being shipped today. Upon receipt of the package and trying the contents, I will update my review again. Sent my payment via Zelle as instructed and have been completely ghosted. Reached out via email and Facebook. Zero response. Stay away.
