About 75% of the time, Thymus PMG works better than Spleen PMG. Thymus tends to help more with infections and supporting the part of your immune system that deals with infections (think T-cells) whereas spleen (think B-cells) tends to help more with allergies, toxicities, and also certain infections. Sometimes it can be hard to know, without testing, which one you should take. So – take Thymus PMG first and if you don’t feel much better in a day or so, then switch to Spleen PMG. You can’t overdose on PMG substances. They are like blueprints of the cell, not actually organ glandular substances that you can overdose on. They help with repair and regeneration of the organ. The PMG supplements help the organ repair by supplying the determinants for cellular repair and also directing stress away from the affected organ so it may heal faster. I have seen almost a 100% need for Thymus PMG in patients for a good two to four weeks after Covid due to the viral effect on the immune system. During Covid, it’s been the 75/25 (thymus/spleen) ratio, as well with other viruses currently circulating. Yes, you will do much better taking them often and at the doses I mention on the sheets. If you’d like (or need) only some Standard Process supplements shipped directly to you, you can order directly from the SHC Approved On-Line store here. Please don’t buy from Amazon or any non-approved Standard Process site. It’s just not cool. I think every time you do a baby seal gets killed by a narwhal. You don’t want that on your conscious. Of course, Chrissy can ship directly from the office especially if you need other products in the same package. Also, NEVER take Thymex without me testing you on it. It’s completely different than Thymus PMG.
