I have had 17 orders now and I keep a table, so here is the honest summary rather than a vibe. Material has been consistent. Communication has not. Shipping has varied…

Been lurking in c/tirzepatide for about 9 months and finally have something worth posting. Short version: week 15, 2.5mg, and area percent is the bit I still cannot get…
Week 10 update. 31kg down from the start, muscle cramps basically gone since about week 62. Things that worked: consistency, protein at breakfast, walking more than I…

Right, the purity question again, but with numbers this time. I have 24 data points over 10 weeks. The pattern is consistent enough that I do not think it is chance,…
