I would like to point out that the Adex raws were something like 92% pure. So not much variation. Grinding the API was crucial to get the small capsules correct and I expect my other capsules will be better now too*raises hand*
The arimidex was 13% underdosed.
Here we go again with my rant on caps... Caps are hard to consistently.
Do the initial measurements wrong and your math is off from the start.
Assuming that your initial measurements are on, then the issue is with the blending. You put the correct amount of API in the batch and one cap is 13% underdosed, the API is somewhere else in another cap. So somewhere else it could be 13% overdosed. It’s all over the place.
1 mg caps are even more difficult because of the small room for error. His Lady Var was off by 20% overdosed (6 mg instead of 5 mg). It makes a difference for these compounds too. Fluctuating doses of arimidex each week makes it difficult to dial in your estrogen levels.
And well aware it’s a UGL. But this kind of stuff separates an “average” UGL from an amazing one. There’s UGLs that can nail these doses time after time consistently. Or buy pharma.
