I certainly don't regret it, but one needs to know it's nothing magical. Ostarine alone doesn't do much for most people.
When looking for my first AAS cycle (next september) I realized it's much cheaper than sarms and much better in terms of results (look at the logs).
Keep in mind that most sarms stacks will cost a sh** ton of money for just one cycle.
I started with ostarine as my first non-natty supplement and I was quite pleased with it. I took the liquid form because the bioavailability is better with liquid osta, but that thing is expensive and only provides enough of the chem for 8 weeks (any cycle longer than that will require another bottle). For relatively the same price as 1 bottle of osta I saw that I could get almost 20 weeks worth of injectable Test at 500mg/week (more than enough).
With SARMS you need a regular on-cycle supplement, good diet, no AI is needed and a complete PCT, which doesn't sound expensive, but most of the money goes into those expensive SARMS.
With an AAS you need a good diet, something to keep blood pressure in check in case your heart starts pumping too much, an AI to keep your estrogen levels on the low side, a good diet and a complete PCT, which may sound expensive but not that much since you get more for your money.
If you look at prohormones then you need a very good on-cycle supplement for your liver (a regular on-cycle supp + TUDCA is what I'd go with), a good diet, something for blood pressure, a AI is absolutely necessary because if you're taking epistane then a estro rebound is most certainly going to happen and you need a complete PCT. Prohormones are considered as the "cheap" alternative (not so cheap), but the side effects are also pretty strong so most professionals tend to stay away from those compounds.
I wont go into specifics in terms of prices, but an AAS cycle with Test, Tbol, Arimidex, Nolva and clomid would be almost half the price you'd pay for a stack of liquid SARMS without including your SERMS in the price. (PS if your liquid sarm is very-very cheap then it most likely not dosed as labeled or there's no SARM in that bottle)
Keep in mind that many online stores don't actually put SARMS in their pills and they put a mild prohormone like epistane instead. That's why you can find ostarine for under 30$ in pills form, because there's no ostarine in that thing but rather a low dosed PH. Should you choose to go with pills rather than liquid i'd suggest you do a lot of research about your source. Imagine thinking you're taking LGD and you end up taking Tren or Superdrol... that can mess you up because you're not going to be prepared for the side effects.
The logs tell you everything you need to know.
Results : AAS > PH > SARMS
Side effects : PH > AAS > SARMS
Costs : SARMS > PH >= AAS
Speedy recovery : SARMS > AAS > PH (prohormones are harsher than injectables)
