Affordable and trusted testing companies….

Good evening! New member posting
I want to first thank Randy and his family creating this community forum! Without your information and advice most of us here would be in the dark. Much appreciated 
My question is what known and trusted companies offer affordable testing prices? What exact tests should we ask for when sending samples? Any insight and info would be grateful!

There is info here https://peptidecritic.com/peptides/testing-providers
Also, peptidetest.com offers group testing, not sure of prices.

Right now (and for the last couple years) my go to is Analytical formulations inc. John over there has been running his lab since 2008 and is a wealth of knowledge. He's the dude. Email [email protected]. He takes a week or less in most cases to get me mass/purity/sterility. Name dropping us cant hurt

Peptide test and trustpoint are basically the same thing. Soon they will split. Depending on where you source testing may or may not be necessary depending on how you like to research.
Janoshik is a disaster to deal with. They doxxed my personal information on their public test page by accident which was really great. Getting them to take it down took a week. The results on mass/purity really depend on who is in the lab that day. You will see the same sample tested 3 days apart and get a +/- 10% result.
On chromate a few vendors I know have ceased using them due to issues with accuracy or mixing up samples.
