I answered his question in the context in which he asked it. The key words being "They say."
Now the facts are this. Pharmaceutical serms, ai's, and da's come in a coated pill form, and are lab tested and made under quality control measures that make them precisely dosed as the package says the are. When you half it, quarter it, or cut it into 8ths it's still precisely dosed. No if, ands, buts, or guessing about it. It is easily adjusted up or down accurately.
Overseas ugl hard pressed tabs are not coated, but are in tab form. They can be accurately dosed or inaccurately dosed, but can be split just like pharmaceutical grade to make small adjustments up or down. Theres more likely than not that there has been zero lab test conducted to ensure accuracy.
Domestic ugl's. Until recently these are items that were rarely carried by dom ugls. I only recall one that did and it was in liquid form. This brings me to the two primary forms that you see domestic ugl's carry. Liquid and capsule. With liquid form the dosing can be very erratic. .5 ml this time could be 12.5mg, the next time 20mg, and the time after that 5mg. As you can see this could and can be very problematic. Again there's most likely no lab testing done to ensure accuracy. Capsule form is good, and can be accurately dosed, but has its own downfalls. It's easily swallowed, but could be inaccurately dosed due to the fact once again its most likely lab test for accuracy have not been done. The main downfall to caps is making small adjustments. You cannot split caps into halves or quarters to make small adjustments.
This is not a knock on overseas or domestic ugl's serms, ai's, or da's. Many of our top sources go to great lengths to ensure quality of product, and take great pride in doing so. This is just the advantages and disadvantages layed out plain as day so that people can make an educated decision based on what's best for thenselves physically and financially because pharmaceutical grade is very expensive.
As for myself I've used every form stated above with success, but being very gyno prone I now only use pharmaceutical grade ai's and da's just for my own peace of mind.
