To answer your question, I am testing it right now. First, BEWARE OF NEWSMEDIA SENSATIONALISM & MARKETING OVERHYPE (the main reason why androstenedione is banned by the IOC, NFL, NCAA, etc. is not because of it's overhyped effects (so what,big deal, caffeine & DHEA is also banned by the International Olympic Comittee, NCAA, etc.) but because it causes users to temporarily test positive for steroid use on drug tests by altering the ratio of testosterone & other hormonal metabolites (thus, any one testing positive for steroid use could claim it was because of he/she was taking androstenedione and not steriods--an excuse that's been eliminated by banning androstenedione).

Despite all the newsmedia sensationalism (McGwire) and marketing overhype of androstenedione, there have been no human (or animal studies) showing the 3 hour rise in testosterone to have a significant anabolic effect. Some users have reported a slight to moderate increase in strength during a workout, though. The East Germans used a NASAL version (and it was for increasing strength due to testosterone's/DHT's stimulating/strengthening effect on the central nervous system/contraction of muscle cells) where it was directly absorbed instead of being degraded by the digestive system. DHT (dihydroxytestosterone) is one of androstene's (undesired) metabolites which is responsible for masculinazing effects such as facial/body hair-growth, baldness, deeper voice, etc. but can also have a slight-to-moderate positive effect on strength due to more neural contraction (not necessarily more muscle growth).

Let's use science/biochemistry to analyze it's possible effects : Androstenedione's effects on healthy young adult males are overblown by the newsmedia and marketers. Normal adult men produce about 3-10 mg of testosterone a day so the temporary 3 hour increase of 50%-180%+ sounds good until you realize that an EFFECTIVE MININUM dose of real anabolic steroids/testosterone is around 30-50+ mg per day total (far above of what androstenedione can provide--only about 5% (5 mg out of a 100 mg dose) of androstenedione is actually converted to testosterone, which is far below the moderate dosage of the 50-100+ mg per day of testosterone provided by real anabolic steroids(or testosterone analogs) which have a much longer half-life (in days, not hours, in the case of injections)and are taken for weeks.

Despite the overhype by its sellers and the newsmedia, androstenedione is nowhere near effective as actual testosterone/steroids, which are 17-BETA-methylakylated compounds (they contain a beta-methylakl group that fits an anabolic receptor on your muscle cells and causes them to grow--the androstenedione molecule lacks this all-important anabolic 17-BETAmethlakhoweveruspellit molecular group (and your body can't add it :). You could say androstenedione has less than 1/20 the strength of real testosterone so why not take 20 pills at a time?

Unfortunately, there's evidence that your body is sensitive to levels of androstendione in the body and will shut down it's own natural testosterone production temporarily so you'll be back to square one and the excess androstenedione can have unwanted side effects like acne, bloating, hair loss, etc.--a preliminary study done by one of the androstene's marketers was killed off because the subjects natural testosterone levels dropped below normal baseline after 2 weeks of continous androstenedione.

With that in mind, the temporary 3 hour boost in testosterone does seem to slightly-to-moderately increase strength & "pumped-upness" during a workout (which doesn't necessarily mean you'll be putting on muscle-strength gains can come from testosterone's/DHT stimulating effects on the central nervous system). I'm experimenting/testing androstenedione now. I didn't see any results at 100-200 mg so now I'm trying 400-900+ mg (I do notice a bit more "pumped-upness" in my muscles after I lift-will post more if I notice/see more muscle (hopefully ;) Placebo or not?

I'm reserving judgement on it. By the way, the 4AD versions of andro is much superior to that of the 5AD versions of andro (which converts even more weakly to testosterone).

Taking androstendione at low dosages (which keeps testosterone levels at/near normal baseline) continuously 24/7 is not recommended as it can shut down natural testosterone production without significant anabolic effect.

So if you do want to test it out and take it, a 2 week on, 2 week off cycle may be best (or you may just blitz it for a 6-8 week on cycle and 12 week off). Expect maybe a small-to-moderate effect on workouts.

Chrysin has no human/animal studies to back it up. While nice in theory, I've received no positive responses/results from anyone using it. Too early to tell if it's a complete washout but don't hold your breath. I tried HMB too and didn't notice anything (but I have other friends who say HMB works for them-maybe they were overtraining, which is how HMB seems to help)

e/c/a- the 5on/2off is fine. Any of the 2/1, 1/1, day/off or 6-8 weeks on/12 weeks off or their variations are just cycling attempts to delay the attenuation. No interactions. Taking only 150 mg of aspirin will benefit the first 10 mg of ephedrine only but you'll still be fine/happy with the fatloss (most studies used eph/caffeine only anyways).
