I assume the dude is some kind of fighter?
Looks like a good stack for such, although the Anavar is suprisingly high imo. Also surprised there is no GH in there, but maybe he just didn't list it?
A fighter naturally wants to avoid unnecessary water/weight and absolutely wants to avoid too much muscle pump/possible cramping.
Different anabolics have different potential benefits for an athlete, I guess it's somewhat individual, as well as which aspects he needs help with. Whether neural drive, muscle recovery, joint protection/less joint pain. On another forum there's one athlete who has meticulously logged his use of different PEDs and their effects on performance. For example, any test above 200mg was detrimental, so preferably like 150mg only. Different orals seemed to have acute effects like on number of chins performed. EQ was a good anabolic on top of the test, good for endurance. Deca may bring too much water even at 100mg and 50mg might be enough for joint benefits.
I think fighters and athletes would potentially benefit a lot from Halotestin, but I'm not talking about the blind rage. They say raging is actually detrimental for fighting. But it does have beneficial neurological effects, I'm liking the effects of it right now, really activating.
Maybe GH at a replacement dose of 2iu every other day with maybe natural GH boosters on the off days, like a shot of ipamorelin and a GHRH. Just enough for some recovery benefits without bringing too much water or causing lethargy.
Smart drugs like the racetams and Noopept and choline sources can help with learning new skills, on paper at least.
EPO I bet would be fantastic even though I have never done it myself, but Chael Sonnen was busted for it (said the big three were test + gh + EPO).
