Eq is good
Look at turinabol as well low doses. Look to see if there is any east German doping data in endurance athletes. There is a lot of data on the hormone because it was used in doping practices all throughott the east Germany period by the olykpic teams.

It is a good hormone.

I don't know if you do weight training but you could add in sokething like 150-200 mg a week testosterone,200-400 mg/w eq 4 IU hgh and 20 mg a day of tbol vduring a mesocycle for endurance weight training in the gym where you are doing say something like high rep squats and working on explosive strength which will have a carry over iirc.

Then when you are focusing on the endurance specific running training you could add in the EPO...pull the tbol and add in halo 3 weeks out from the race.

I wouldn't try all these hormones at once though. It's risky that you could in fact get sides and damage your performance (more isn't better). But I don't know..I only ever really did a lot of strength training got really bgood at it for a while got hurt did bbijg got a good physique for a while and now i am currently a fat 20 yr old typing this after doing 2 hrs of physio so again as previously mentioned don't take my advice as religious!

I suggest getting in contact with a coach that knows about PEDs for endurance bathletes.

Afaik the crowd around here is:
Competitive BBers who are in tip top shape ie big guys...followed by
Recreation gym rats who are likely out of shape looking for something to get in shape for holiday coming up then go off their leangain get depressed and get out of shape again
Followed by power athletes

Lol

Not the best crowd to help you here, unfortunately! And I certainly will not go into EPO use. I am not knowledgeable enough AT ALL. That stuff can and will really damage you if used improperly. I know of a guy who simply got sent 5000 iu vials not 2000 iu didn't check ended up taking 2.5x the dose he thought he was ended up with an hct of about 0.7-0.8 after being rushed to hospital after nearly dying in his sleep apparently.
