I'm all in on making informed choices about peptides.
My attempt at being helpful is a Quality vs Price comparison spreadsheet of US Peptide vendors.
I began compiling it when I saw the end of insured Wegovy rapidly approaching.
There is a bit of a preamble then a link to a Google Drive permalink.
Feel free to make suggestions for improvement, it's a work in progress:
-----
" When I lost my group insurance I searched for low-cost Wegovy replacements. I found huge price differences between vendors, and, QA practices that varied widely.
To be helpful I compiled my results on 20+ US GLP-1 vendors who will sell single vials. Prices are shown for research Semaglutide, Tirzepatide and Retrutatide. Color coding and QA Notes have relevant Quality Info.
The PREFERRED, MOST TRANSPARENT Quality Assurance for peptide users is a Batch Certificate of Anaysis (COA) prepared by an Independent 3rd Party laboratory that is Current, Credible AND LINKED TO EVERY VIAL (LTEV) SOLD. The linking may be by batch number on the vial label, printed QR code hyperlinked to an online COA, or by a naming convention which uniquely identifies the product as part of a unique COA'd batch. Some *** vendors do all three things.
A COA shows the IDENTITY, PURITY and QUANTITY of peptide present in the sample vial. PURITY of product must be Pharmaceutical Grade per the United States Pharmacoepeia (USP) i.e. above 99% pure. QUANTITY MUST BE SPECIFIED AS IT IS ESSENTIAL to obtaining the correct dosage when you reconstitute lypophilized peptides. Some vendors omit QUANTITY as it would reveal their under-dosed, weak and therefore more profitable product offerings - you should not purchase from these vendors.
*** VENDORS with COAs LTEV are considered Highest Quality, marked with a triple asterisk (***) and are sorted to first on this spreadsheet. Strongly consider these vendors if buying the most highly Quality Assured GLP-1 product is your goal.
GREEN = GOOD - HAS PRESENT Current Credible 3RD Party Certificate Of Analysis (COA) showing Identity, Purity and Quantity of peptide. Not necessarily LTEV but observable onsite.
YELLOW = CAUTION - LACKS Current Credible 3RD Party COA OR Has Unsatisfactory Processes OR there is notable, credible negative reporting by users. This last is my own observation and is subjective.
YELLOW/GREEN = MIXED RESULTS Check QA notes for further information before making a purchase.
FULL DISCLOSURE: Information was obtained by organic Google Searches and my own non-medical-professional observations. It is believed accurate at posted DATE on spreadsheet but not guaranteed. My wife's Semaglutide comes from Aminos Research while my own Semaglutide, Tirzepatide and Retatrutide has come partially from Aminos Research and also from other less well QA'd sources. I do not accept any form of compensation from any source, and, I prefer not to 'recommend' individual vendors. "
