I just did the math for making my own 1-test/4 ad homebrew (not for use, for soliciting, of course ) and I came up with this:
(these are 1fast400 hormone prices, which are about the cheapest there are)
1 4oz T-Gel - $20.00
3 grams 1-Test- $12.00
4.5 grams 4 ad- $4.50
Whereas for the exact same ingredients, S1+ is $32.50.
Have I made some calculation error or overlooked some big detail?
