Complete scam site Complete scam site. They run two sites ones a selective scam site and this site is a full blown scam site. You might get something in the mail, but with no ingredients. Thats why if you type in the domain (it’s up now but try pulling it up ina month or two it’ll be down) spectra is a complete scam. DO NOT BUY FROM THESE GUYS TRUST ME!

Another good experience Another good experience. This batch wasn't quite as good as the last batch from a week ago. It seems to go like that from batch to batch. I don't think it's the sellers fault, as I don't believe they mix their own solutions. I've never gotten anything totally bunk, but some batches are definitely better than others. Still happy with the order despite slightly underwhelming testing on GCMS dosage wise. 5 stars nonetheless for convenience and longevity. I've placed probably 50 orders and never had an issue besides some batches being more concentrated than others. The batch I got last week was amazing, this batch is OK. Still happy.

Rcs are EXTREMELY watered down nothing… Rcs are EXTREMELY watered down nothing near the CORRECT dosing labeled. Did a sample order it was pretty much a bottle ethanol alcohol and Propylene glycol with about 25-30% of actual ingredient emailed them they apologized saying there was a shortage which I never understood if there’s a shortage then sell what you have at correct dosing as labeled correct potency then put the item out of stock dont just sell your customers a bunch of bottles of binders “ethanol&PG as previously mentioned” still gave them another order not to big around 4-500$ SAME SH!T!! Highly DO NOT RECOMMEND giving them the 2 stars literally for not being complete scammers

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.

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.
