I doubt those results would transfer to visable real world results worth the cash or headache. This is also pct which is a prime place for an accelerated rate of muscle loss. Mk677> Clen on that subject imo.
Orthopedic patients and chronic heart failure patients maybe but a person in pct? we can agree to disagree on this one.
Both sources you posted parroted and referenced the same studies and with those studies in front of my eye I'm willing to admit that Clen is not useless. However imo it is useless in pct because of either better options or the guarantee that you won't be jettisoned into losing weight.
The goal of pct should be to maintain weight the best you can, even put on 1 or 2 lbs with the intention of maintaining what you have earned on cycle. Minus the water loss and such.
I used clen on maintenance calories and was genuinely surprised in the strength and LBM gains. and for the price, far superior to MK, in my opinion. MK made me hold water and hungry all the time.
clen's been used in PCT for years, successfully.
I'm sure some people's opinion of it's effectiveness is tainted by their weight loss regimens at the time they used it.
but clinically and anecdotally, it has plenty of evidence to show that it works.
