I've never used it, nor do I know anyone who has...but it does not contain any "secret" ingredients. It's just a bunch of supps all wrapped into one, which is typical of Animal Stack products.
Here are the ingredients:
Supplement Facts
Serving Size = 1 pack
Per Serving:
Vitamin C (as ascorbic acid) - 50mg
Vitamin B6 (as pyridoxine HCl) - 10mg
Calcium (as calcium phosphate) - 150mg
Magnesium (as oxide) - 100mg
Zinc (as picolinate) - 30mg
Natural Flavone Complex
Basically this is a typical ZMA recipe.
5-Methyl-7-Methoxyisoflavone - 100mg
7-Isopropoxyisoflavone (Ipriflavone) - 100mg
20-Hydroxyecdysone (Beta-Ecdysterone) - 100mg
Growth Hormone (hGH) Secretagogues
5-Methyl-7-Methoxyisoflavone & 7-Isopropoxyisoflavone are supposed to be "anabolic" but I have not seen any real science behind them.
L-Arginine Pyroglutamate - 2.5g
L-Ornithine Alpha-Ketoglutarate - 1.3g
Lysine (as lysine HCl) - 1.2g
Taurine (as L-taurine) - 750mg
Leucine (as L-leucine) - 100mg
Isoleucine (as L-isoleucine) - 50mg
Valine (as L-valine) - 50mg
Lutenizing Hormone (LH) Boosters
Basically just amino acids here.
Tribulus Extract (20-29% saponins) - 250mg
Acetyl-L-Carnitine - 250mg
Carnitine (as L-carnitine) - 50mg
Anti-Aromatase Inhibitors
Tribulus works if it actually contains the correct saponins and the amount they claim.
Chrysin - 100mg
Kudzu (herb) - 150mg
DHT Blockers
Saw Palmetto (fruit) - 200mg
These are estrogen blockers. Saw Palmetto is supposed to work as a treatment for a enlarged prostate.
Beta Sitosterol - 250mg
Pygeum africanum Hook.f. (bark) - 50mg
Insulin Potentiators
Not sure what the hell these are!
Alpha Lipoic Acid - 10mg
Chromium Picolinate - 100mcg
Metabolic Energy Complex
ALA is a antioxidant, Chromium is supposed to facilitates the action of insulin and be "anabolic", but I believe the claims are all unsubstantiated.
Guarana Extract (22% caffeine) - 500mg
Bitter Orange Extract (4% synephrine) - 400mg
Cordyceps Extract (7% cordyceptic acid) - 100mg
Liver Detoxyifying Complex
Lysophosphatidylcholine (as Lecithin) - 50mg
Milk Thistle - 75mg
In conclusion, I would not waste my money on it.
Instead I would by a few of the ingredients separately, such as ZMA.
