It has been a minute since I've logged something, but I'm a huge fan of Antaeus Labs. Achilles, Oneiromancer, both dynamite products!
I was planning on picking up a bottle of Thunderbolt just to give the novel pump ingredients a try to see if it is superior to the usual Citrulline, Agmatine, AAKG, GPLC, PF3 based formulas. Over the years everyone comes out with a "pump" product, so far I think the best pumps come from a great workout and a good stim-based preworkout. Arnold presses, rope handle upright rows, and pull ups to muscle failure are the best upper body pump exercises to get a great swole going. And, the best preworkout in the past 5 years is MAN sports GameDay, decent pump, phenomenal focus!
Sometimes a great pump is elusive, for me personally, the only way I can get a great leg pump is by going on a super long and brutal trail run. Forearm pumps come from rock climbing or bouldering, it all depends on what I need to be stronger at the time. Currently, I am getting ready for trail running season by dropping 10-12 lbs over the next two months, letting my upper body and calves atrophy so I'm not carrying or fighting extra muscle mass.
I'm picking up a bottle either way, but I am curious If Antaeus has some T-shirts available?
