The PHDB Breakdown:
2-cyano-17a-methyl-17b-acetoxy-5a-androst-2-ene: 20mg
Per recommended dosage: 20-40mg daily
Community consensus: 30mg daily for new users, up to 40mg daily for experienced users, 4-5 week cycle

2a,3a-epithio-17a-methyl-5aandrostan-17b-ol: 15mg
Per Recommended dosage: 15-30mg daily
Community consensus: 30-40mg daily for 4-5 week cycle

4-chloro-17a-methyl-andro-4-ene,17b-dio: 25mg
Per recommended dosage: 25-50mg daily
Community consensus: 50-75mg daily for 5-6 week cycles

So right out the gate, I think given assumed permission to run for 8 weeks is a bad idea.

As far as dosing, this one is pretty good.... if you were taking each compound by itself. But you're not. You could run any one of these independently and, provided you ate well and exercised, you'd see decent results.

The onyl if-factor is is cynostane. The community seems split. Some users report great results, some mediocre resuls, and some say it didn't work for them at all.

I'm guess as of my writing this, that Xtreme Definitions is pretty new, because I can't find any logs or review for it.
The three compounds in it are pretty well know though.

2a,3a-epithio-17a-methyl-5a-androstan-17b-ol (Havoc/Epistane)

Also written as: 2a,3a-epithio-17a-methyl-17b-hydroxy-5a-adrostan

Trade names include Havoc/Epistane
Common Dosages: 30mg to 40mg daily
Common Cycle Length: 4-5 Weeks
Methylated: Yes
Half-Life: Average (6-8 hours)

A designer steroid and legal alternative to anabolic and androgenic steroids.

Epistane is a methylated version of the controlled substance Epitiostanol (2,3-Epithio-5-androstan-17-ol), created in the 1960's and used as a treatment for breast cancer. Chemists added a methyl group to the compound to create the product known as Epistane. Epistane is a sulfur containing steroid which is known to have strong and long lasting anti-estrogenic activity as well as weak androgenic and mytropic activities.

Since it is anti-estrogenic, you can expect very dry gains from this compound. Epistane has low androgenic to anabolic activity, meaning it is much more anabolic then androgenic. Even though users will see dry gains on Epistane it does not mean that it would be any insufficient for a bulking cycle.

Side effects are typically minimal to non existent.

2-cyano-17a-methyl-17b-acetoxy-5a-androst-2-ene (Cyanostane)

Another nomenclature used for the Cynostane compound.

2-cyano-17a-methyl-17b-hydroxy-androst-3-one (Cynostane)

Has a methyl group and hydroxyl group off of the 17th carbon. A methyl group has single bonds from a carbon to 3 hydrogens leaving the 4th bond open to bond to whatever, in this case the 17th carbon.. A hydroxyl group has a oxygen single bond to a hydrogen and another single bond to whatever, which in this case is the 17th carbon. Has a 2 and 3, both connect to the 17th carbon where the R is on the pictures on the links.

2-cyano-17a-methyl-17b-acetoxy-5a-androst-2-ene (Cynostane)

Has the same methyl group at the 17th position but also has a acetoxy group. A acetoxy group has an oxygen single bond to a carbon, off of this carbon is a double bond to an oxygen and also has a methyl group off of this carbon. The oxygen with the single bond to carbon is left with one bond free, it is here that bonds to the 17th carbon. Has a 1 and 2, both connect to the 17th carbon where the R is on the pictures in the links.

Cynostane features an alteration of the superdrol compound, with a cyano bond instead of the 2a methyl superdrol bond.

Cynostane is an extremely anabolic compound with remarkably low androgenic action, making it similar to Oxandrolone or Methenolone (primobolan). It's non-aromatizing meaning it won't produce estrogen mediated side effects and its high degree of anabolic action makes it a good choice for athletes wanting to lose bodyfat while maintaining, or increasing, muscle mass.

Blood work shows Cynostane has a less detrimental effect on blood lipids, and liver values than Superdrol. The combination of low androgenic action, lack of aromatization to estrogen, and low level of general health effects, makes cynostane an intriguing compound.

Its not going to be as powerful as superdrol in the strength department but it will be great for size and some good strength to. At the same time it is also not nearly as liver or lipid toxic ether.

This compound definitely appears to have oral activity, and very potent activity at that. It has the highest Q ratio, 20. That is the same Q ratio as superdrol, except this compound appears to be twice as anabolic as superdrol. I would expect dry gains, more similar to oxandrolone (anavar).

On the FDA ban list, so get it while you can!

4-chloro-17a-methyl-androst-4-ene-3b,17b-diol (Promagnon)

Also sold as Promag, P-Mag
Common Dosage: 50 - 100mg daily
Common Cycle Length: 4-6 Weeks.
Methylated: Yes
Half-Life: 12 hours

Another methylated prohormone, this one is often compared to halodrol, though there is an important structural difference. P-mag lacks the C1-2 double bond common to boldenone derivatives like h-drol, boldione, dbol and M1,4ADD, having only a C4-5 (delta-4) double bond which makes it a closer structural relative of testosterone and methyl testosterone.

The difference becomes apparent when we look at what each one becomes in vivo: where some h-drol is metabolised via 3b-HSD to oral turinabol, p-mag becomes methylated clostebol. A 4-chloro group is common to both drugs, which will make both poor substrates for the aromatase cytochrome P-450 enzyme.

Clostebol is a synthetic anabolic androgenic steroid. Clostebol is the 4-chloro derivative of the natural hormone testosterone. It is a weak anabolic steroid used often by Germans during their Olympic glory days.

Promagnon users report size gains, with a lack of additional weight added in the last couple of weeks. Libido tends to remain positive, likely due to the more androgenic qualities of the drug.

The aforementioned positive attributes and the possibility of short cycle durations would make this an excellent choice for a first cycle, though as with any methyl it is a good idea to educate yourself about the possibilities of hepatic impairment

Promag is a versatile compound that will produce lean muscular gains and is suitable for cutting or bulking, however is typically most used when bulking Promag remains a popular due to minimal side effects and consistent dry gains that are relatively easy to maintain post cycle.
