pulsing is dangerous because it gives people that idea that they can safely run a cycle of steroids with little no side effects, including no preparation for said side effects.
Pulsing is also dangerous because people are trying to pulse un-pulsable compunds, such as m1t. m1t cannot be pulsed because its supressive effect is so pronounced even 2 days of dosing can cause shutdown.
people argue that they are not "supressed or shut down" after pulsing, even though they provide no blood work to support their claims. a sub-par post cycle therapy is then run.
pulsing causes large fluctuations in hormones. although liver stress may be decreased by less dosing, the hormonal damage is in all likelihood just as bad. It is not just the hormone that is fluctuating, but estrogen, LH, FSH, activin, inhibin, SHBG, and cortisol. These hormones, especially (and most importantly) cortisol, have time to normalize(acclimatize) during a normal cycle. They DO NOT during a pulsing cycle. This is will lead to MORE side effects.
The pulsing method seems to be a partially recycled "tapering" method that was used back in the 70's and 80's. Nothing new, really. THe only evidence i have seen that the pulsing method works are claims by Dr. D that he recovered from pulsing cycles back when he was 18 years old. Again, with no bloodwork to substantiate.
anyone who runs a "pulse" is looking for a shortcut, and a one that is absolutely not safe, at that.
