The cost effectiveness varies for each PH. For instance, for m14AD its not all
that cost effective, while for
1-AD it becomes very cost effective in higher amounts. Also for
m4ohn it is quite effective.
On things like
1-AD I'm sure putting the daily amount in a drink or such wouldnt be a terrible idea (long as you have an accurate scale) but for something like
m4ohn or
mdien where you want a very small, very specific amount, you would want to create a solution out of something like PEG400 or even bacardi 151/everclear. This way, you could get a known concentration per milliliter. Some compounds, like
m5aa, are difficult to get into solution, while others are very easy.
For the compounds you are speaking of (taken orally I'm assuming) it would be much more cost effective to buy in bulk and create oral solutions or even just measure out a known amount and throw it into a
protein shake (or even cap it if you have access).
