What aids in strength? Im not looking for muscle builders, rather to aid in power lifts.
ArA
HGW
What else would help?
I just read the OP, have not seen if this has been recommended or not but here comes a little shot hehe...
Ok Personally I have seen huge increases in strength (and when I say huge, lets keep it real hehe...for a supplement it's huge) in the 5 lb ranges for upper body power lifts and 10 lb ranges for the lower body power lifts in around 6-8 weeks. It does seem like a bit, but when powerlifting...heck any pound is a blessing. While I am still in recovery from a surgery I had, before the surgery this helped a lot to help me progress my powerlifting dreams, and so did it do it for my friend/team captain.
-ArA: we used both X-Gels and X-Factor, since well haha...X-Gels hadn't dropped in when we started, and because it is also pure ArA. 1.5-2.5g pre-workout.
-COP:2g Pre-workout
-25mg Ephedrine (be it sulfate or HCL) with 200-250mg caffeine , 3x a day.
-Citrulline Malate: 6-9g a day
-Glycergrow: 2 scoops pre workout too.
-1-1.5g agmatine sulfate preworkout.
-1g LCLT + 1g ALCAR preworkout
It does sound like quite the cocktail haha but in fact it was just EC + ArA and it's ancillaries...Arachidonic Acid paired with a good periodized routine for strength building, focusing both on myofibrillar and sarcoplasmic hypertrophy proved amazing for both of us. The reason behind the EC was not only for the Stim and focus (and with alcar too...damn it was nice, sometimes we would supp the caff with Focus-XT haha, or add Stim Free Focus-XT), but because Ephedrine is a bronchodilator and it aids in Peak Power output. The reason we took Cit-Mal and also Agmatine was due to that too, more vasodilation , more power output and lastly...COP will aid in recovery in between sets, it actually helped me catch my breath faster after a heavy set , or a gruesome muscle building assistance like Good Mornings in sets of 10 or 15 haha.
That's in my experience what has helped a lot, Vasodilation , Broncodilation and muscle inflammation with ArA...but to all this: FOOD, lots of FOOD, key supplement IMO for strength, food and rest hahaha.
Other supplements I have seen personally strength rises from (albeit i did not take them for that but still felt them):
-AnaBeta (OG and Elite)
-Versa 1 (can't tell if placebo or not, but yes it was there, so heck even placebo is welcomed)
Hope that helps
