Well, what it sounds like is that he wants one drug, no stacking, minimal sides, no water retention, and cheap.
So, we have...
primo: too expensive
oxandrolone: too expensive
winny: probably too expensive, but a possibility
fina: too impractical... i.e. he would have to make it himself, take it at least eod, and should really stack it with test
eq: cheap, effective, no water, minimal sides, no results for 4-5 weeks...this might be an option
test: no, too much possibility for sides, water, etc.
deca: water retention, and fairly expensive
anadrol: are you kidding me? Water water everywhere!
dbol: see above
Basically, it sounds like what he wants is what most people refer to as 'cutting drugs'. It seems to me that depending on $, he could go with either injectible or oral. Sure, oral is going to be easier on his body, but he could do a 6 week winny cycle.
Or he could do an 8-10 week eq cycle.
I would say either do winny at 50mg/day for 6 weeks or eq at 400/mg week for 8-10 weeks. The eq will be cheaper and fits all of his criteria. You could spend less than $200 for the ttokkyo eq and have enough for this cycle. And with eq, it would be one inject/week.
Do some searches and read up on eq, or tell him to. It's his body he should put some effort into finding out a little about this.
