Reta 30mg Tests at 100% purity

[nogainz]

Greetings:

I know generally there is a movement to discredit all things Finnrick with regard to testing. "They are the FDA"..."they are up to something sketchy, but we don't know what yet" etc etc. But I simply ignore their arbitrary scoring system and pay attention to what I get out of them...HPLC analysis of purity and quantity. Free testing has saved me thousands this year alone.

My latest result is here for a 30mg Reta vial (PDF also attached):

I'll take a 15% overfill and 100% purity all day. Something that is also interesting is the information in the graph about excipient contents in the vial. Seems our average peptide vial has more than equal parts excipients like mannitol. But even folks like me who do 5-6 daily injections, the aggregate mannitol content seems innocuous. Here's what GPT had to say about it:

ChatGPT - Excipients in Retatrutide vial

Has anyone encountered contradictory information about aggregate mannitol exposure over time?

How do you even know if its mannitol?
I dont see anywhere putting this.

Have you asked the lab what do they classify as excipients vs junk/contamination? There was a vendor who has disinfectant in their pep vials, i wonder how these labs would classify them.

I don't. Just going off the mention in the report: "FTIR sample spectrum confirms the presence of peptide with addition of excipient(s)/fillers such as mannitol."

I have a call into the lab to see if they can be more specific.

I will report back once I talk to them. My sense from the report is that they would bucket all non-peptide content together in that category.

HPLC doesn't care about your feelings. Assays are assays.

It not that black and white. So many factors that can effect a result. Even just improper maintenance of the equipment comes into play. Not to mention it can be just straight up fake lol.

A result being 100% sure as hell doesn’t help their case, bro.

100% looks fake atleast do 99.999

So if you send a sample of your tap water to be checked for contamination, and the lab runs it through a sterilizing grade filter that removes everything down to bacteria sized particles first, does a “100% pure” result mean it’s safe to drink?
