I saw these listed on my suppliers newest price list. Apparently they are the newest GLP-1's being tested. I think the Survo is further along in testing and it may be Lilly's but I'm finding I'm getting tolerance up on Tirz so thinking I need to switch around. I do have Reta to switch. Wondering about these new ones? Plus any suggestions from those who also developed tolerance on tirz would be helpful. Thanks.
