Personally, I would much rather do a full cycle over a lot of what is available otc at the moment. But one of the big draws was the price. For the price of one normal cycle, you can pretty much buy 5 oral over the counter cycles. Which is why it blows my mind that some people spend upwards of 200 dollars for their orals and so many garbage supplements for PCT on on cycle support. Also, short cycles are nice. 3 to 4 weeks, you re in and you re out. Theoretically, you should be able to bring your natural test back in line much quicker than if you were shut down for 4 months. And also they are readily available. You pay less, get them much faster, and don't have to worry about customs intercepting them.
But I don't think its an either/or issue. I think having them available is simply another tool to give you a boost when gains begin to slow. You're not going to get the kind of physique altering results that you'd get from an injectable cycle, but they do offer a nice way to supplement your current program.
