Hey there b dad, hopefully I can give you a hand. I am no expert but I do know a little. I had to look up omnedren and here is what i found:
This preparation is quite similar to Sustanon, and is different only in that 100 mg/mL of it (of 250 mg/mL total) is testosterone hexanoate instead of the testosterone decanoate used in Sustanon. For this reason, Omnadren has a shorter half life, and will give a faster initial increase in blood level. This accounts for the claim of increased water retention and increased side effects, since levels, at first, are higher for the same dosage.
The claim that Omnadren has a duration effect of "a good 2-3 weeks" is somewhat misleading since the half life of the longest lived component is only about 5 days. There is of course some effect 2 or 3 weeks after injection, but relatively little.
The hexanoate ester is quite similar to the well known enanthate ester, but is shorter by one carbon.
The isohexanoate ester in Omnadren is the same, only named differently, as the isocaproate ester in Sustanon. Thus, the hexanoate vs. decanoate difference is the only difference in the mixture of esters.
To sum it all up, this is a relativeley long lasting test combo. Here is some info on Sustanon:
Oxymetholone is without a doubt the strongest and most visibly active steroid to date. Not only does it act very rapidly, it causes a virtual explosion of mass.

Characteristics:
Oxymetholone is without a doubt the strongest and most visibly active steroid to date. Not only does it act very rapidly, it causes a virtual explosion of mass. Gains of up to 10 pounds in 2 weeks are not uncommon. This is largely due to a moderate to low androgenic effect combined with a high anabolic activity also mediated by non-AR mechanisms (mechanisms other than simply binding the androgen receptor). You can imagine that the gains made on oxymetholone aren't the leanest. You would note a drastic smoothing out of the muscle due to estrogen-related fat (lipolysis) and water retention. This lipolysis has been shown to be rather drastic. One study1 on long-term hemodialysis patients showed beyond a doubt the role that oxymetholone can play in causing hyperlipedemia. The fat deposition rate, post-hepatic (after processing by the liver), increased drastically in the oxymetholone group while numbers remained stable in the control group.
Now these are only a semi highlight sheet for these drugs and not all info. Just some reading material for ya

. Now on to my opinion.
I am assuming that the mention of former modeling means that you would like to look lean and muscular again. Well, Anadrol and Sust are not really the best choices. A50 will put tons of mass on you in a very short time but will also lead to fat gain and bad water retention which leads to bloating. the sust will do this too but not a s bad and you really need to worry about estrogen related sides with this combo like gynocomastia (bitxh tits). To prevent this you need to add nolvadex PCT to avoid the growth of breast tissue. some will say add clomid as well but IME and according to some very well respected guys in the industry clomid is not necessary if using nolva. Clomid will also make you feel very emotional. Furthermore, this combo will also make you feel less, not more virile because of the major suppression of the HPTA it causes. Your natural test gets shut down very quickly with this combo and I would advise using some arimidex during the cycle to help with the water retention and e-related sides.
Now on to cycle two. This is by far a better stack for what you are looking for. EQ and winny make a nice combo and are often used as a cutting stack with great success. It doesnt seem like you a competitive bb so I would recommend using 300 mg or EQ per week along with 50 mg of winny every day. You can inject the EQ once per week since the ester is so long lasting. There should be no estrogen related sides with this as neither steroid aromatizes and a much milder PCT can be used. I would recommend a 4 week nolva run of 40/40/20/20. Winny can be harsh on the liver so dont go over 6 weeks. EQ can make you very hungry, but am sure you know this.
In closing, dont use the winny/EQ cycle until you give your body some time to recover from A50 and Sust. No offense, but it doesnt seem like you have researched this combo very well and i dont want you jumping right into another cycle without giving your body enough time to recover. Give it a good 4 months after PCT untill you do this cycle. Also, take that time to read about the compunds so you can plan your PCT, diet, training, etc. And in the future, stay away from the monster mass building steroids like a50, dbol, etc. if you are not competing and just want to look and feel good these have no place in my opinion.
I hope this helps. I am by no means an expert and hopefully some of the more educated guys can jump in with anything i missed. Good luck
