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.

Avoid at all costs Avoid at all costs. It’s a scam site and they ship products that have no active ingredient. The bottle, site, labels, dosages and everything may look correct but what you actually receive is not. What you receive is basically just a little bottle of water. Now I’m scrambling because I have to find a real supplier of the thing I ordered. Save yourself the hassle and stress and just pay for a real product from a reputable site. Do not let PeptidesForSale.net deceive you.

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.

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.

Research chemicals way way way to water down with ethanol, alcohol and propyleneglycol very little active ingredient I give 2 stars because they are great with communication rate with shipping time but all in all, you have to remember that if they are not delivering on the product you were buying then why bother to be honest, I have ordered from them for going on two years now the solutions And the benzo research chemical area. I have gotten nothing but weaker more saturated them with ethanol alcohol in propyleneglycol you can hardly even taste the active ingredient in it anymore. Have to dose up to 3×25 times the amount you would normally dose
