New venders in testing
šØ Hey everyone , I just wanna let you know that we have a new vendor and testing and they are blessing us with 20 samples for me to go get tested to confirm purity and sterility. ā
This company does already have testing done from a reputable testing facility. But as you know, our goal is to always test and verify all batches that we purchase. I will keep you guys updated. As soon as testing pass, I will be adding them to our verified vendors and COA classroom page.

Yes Iām awaiting shipment. The beauty here is we are going to have multiple COAās for this vendor not just a couple of the main ones. I will provide the list of samples that are on way in my post.

Awesome glad to have you I will provide as much information as possible! Any questions suggestions for content donāt hesitate to ask! As for testing facilities there is a free one but they only test a few select peptides. Itās called finnrick.com a newer up and coming facility that Iām actually going to be using. They have good price point at $150 per sample. iLs-labs.com And we do have 2 reputable sources overseas but we have not got through the full testing process tonawuire our own CoA yet thatās why they are not posted.

11lbs weight loss!
One of my friends is on Retatrutide he just started 2 weeks ago, he lost a couple pounds first week but week 2 down 11lbs! Why did he lose so much weight so quick ? Well we all react differently to weight loss. What he did to accelerate the weight loss was he changed his diet and also committed to long fasting hours with low caloric intake. Congrats š to Rob although he isnāt part of the community I thought k would share .

@Kenneth Holbrook yes it was a pretty quick weight loss, but he did a strong fast with very low caloric intake.
