Did they move their website because I get a notice when I click the link that they did? Thanks

You are the man! So many sales!
Not sure if we have a code for Biolongevity Labs but they have a big sale on too.
@ResearchCat they have a never ending sale it seems. They just change the name. JAYC is on code

@Shifted aren't they the same company?

I'm not sure exactly how they are connected or associated with each other (along with ameanopeptides). Their peptides all share CoAs and their payment systems are similar (when they started their labor day sales they started only accepting Bitcoin as crypto payments when they accepted other crypto before the sale). They very well might be the same company.

I don't know if this list is exclusive to vendors on Randys list or not, if so, Randy can delete. Peptagon has some real nice deals, even on two vials (didn't try one), free shipping! I've bought good Cartalax from them and this one of TA-1. Check it out. peptagon.com
