Male/Super Ginseng formulas seem very expensive

Am I reading the usage directions right? For the Male formula, it says 60 drops, 2 to 4 times a day. I read that one stopper full of liquid is 35 drops (thanks for making it easy on me, btw, two drops = 75?), so, that's two stoppers a serving (even though its 75 drops, I don't know how you are supposed to figure 60). That being the case, that means each bottle has less than 20 days worth of dosing, if you are JUST doing the minimum 2 servings a day.

The Super Ginseng is even worse. It only has 20 servings in its bottle, and requires the same amount of drops per serving. That means you get less than 10 days of dosages, again, at the very minimum.

This breaks down to the following, per month, at the MINIMUM dosage, which may or may not be enough to be effective:

Male formula, two bottles a month: $60
Ginseng formula, four bottles a month: $120
Total: $180/month, sans shipping, tax, etc

Again, this is the minimum dosage. It will cost more to do higher, more effective dosages.

From everyone's personal experience, is this consistent with what people have been paying? Have the effects truly been worth the cost? If it works as described, then I suppose $200+ a month might be worth it, but...wow. That's not cheap.
