What is "pulse" cycling? Pulsing is a method of dosing a product designed to intentionally avoid potential long term side effects such as HPTA suppression and liver damage. This technique is usually applied as a means of toxicity control when potent corticoids are used on children requiring long term therapy. However, this method can be applied to anyone using any oral steroid with great success and significantly reduced side effects. With pulsing, the serious long term side effects of chronic oral treatment are avoided and short term side effect like acne and mineral retention are much milder that usual. This allows for higher doses to be used since the dosing is less frequent. For example, if you would normally take a product at 30 mg/day, that equals a total intake of 210 mg/week. While pulsing, you might typically take 40 mg on work out days only, 3 times per week. That only comes out to 120 mg/week total! This provides the needed benefits of the product at the most crucial times, which are just before and just after a work out, and offers a means of avoiding the suppression of endogenous steroid production one would expect on a standard, daily dosing cycle. In other words, you can often pulse a compound for 6-8 weeks before you realistically need to start thinking about a conventional post cycle therapy. After a 4 week pulsing cycle, post cycle therapy should not even be required in most cases!
Basically, if you dose every day (ED) in perfectly spaced doses, you will achieve 100% effect, 100% short term side effects, and 100% long term side effects. If you dose every other day (EOD) like the pulse protocol, you still get about 60% effect and 75% short term sides, but only about 40% of the long term sides. That's not a bad trade off and very economical on the body and as well as the wallet! Of course, if you would have gained 10 pounds on a standard 1 month cycle, you will only gain about 6 pounds per month pulsing, but it also means you can do this for twice as long as a standard cycle. That equals about 2 months of worry free dosing, so the net effect is a gain of about 12 pounds over 2 months instead of 10 pounds over 1 month. This structure offers fewer sides and a milder post cycle therapy requirement (if even needed at all) plus the slower gains tend to have a better residual that is more likely to be permanent compared to faster gains. It's a great long term strategy for vets wanting to run 12 weeks, and good for new users too looking to run fast and clean 1 month cycles with no post cycle therapy needed later.
