your cost effective thing is a non-issue. by the gram it is very cheap, and is sold by this weight in powder form. i am not opining on the quality of m-4-ad as a substance as compared to the others, but price is not an issue if you buy it in powder form. it's $5 a gram in powder form. at 200 mg a day, that would be 25 days for $5 (plus the cost of the carrier, which would probably be no more than $1-$2. is it really that hard to make your OWN oral solution/suspension? that's a rhetorical question. you pay a lot more for convenience, if you buy it already in liquid form. DS offers it in powder form, and that is the way to buy it for cost effectiveness.
i also agree with DS that (in general) esterified prohormones (1-test cyp, 4-ad prop, etc.) placed into solution or even unesterified prohormones placed into suspension for injection are going to be better/safer/more effective options, in general, than methyls. pinning is NOT illegal, contrary to popular belief. substances are, or are not illegal. converting a legal substance into an injectable form is not illegal, unless the parent substance itself is illegal. for those who have valid reasons for not pinning, that's fine. but for those who want to use solely methyls to avoid the pain or stigma of pinning, that would be silly. pinning ph's is legal, incredibly effective, and very cheap. 4-ad base, which makes a decent suspension is under $1 a gram. it doesn't get much cheaper than that.
