User questions & answers

Question:	Is this unit easy to use
Answer:	It is Informed Choice certified so its significantly more likely to be clean from banned substances. However, supplements are NOT regulated by the FDA so unless you send the individual batch to an independent testing lab there is no way to know 100%. But it would be "testosterone" that they put in supplements anyways, rather substances to boost testosterone production.

Question:	Does this make my pinocchio big down star overtime usages
Answer:	The only thing I can think of is the dessicant module got overcome by humidity. Or the lid wasn't on right. If you live in high humidity, that may be the reason as well. I know it's not an answer but some possibilities. If, when opened, it was like that, I'd send it back because the integrity seal had to be compromised.

User questions & answers

Question:	Keto friendly
Answer:	It’s good for a “controlled” reaction, intense enough to “feel it,” but not overwhelm you. That’s why I like this one.
Question:	should i take them on resting days i mean only the days i traing
Answer:	Most of our products are manufactured in the facilities that also process milk, egg, peanut, tree nuts, soy, wheat, fish and crustacean shellfish. C4 Ripped Sport does contain a small amount of milk because it contains L-Carnitine, which supports the transformation of fatty acids into energy.
Question:	Which is better threeatine or creatine hci
Answer:	No, 2 scoops is not 30 servings.
Question:	There are no specifications on the loading phase needed for this specific product -Is loading phase not required for this
Answer:	Hi Zach, Thank you for contacting RSP Nutrition! AminoLean works great as a morning pick-me-up or a gentle preworkout (there is only 125mg of caffeine per serving, about the same as a 10oz cup of coffee from your favorite local chain), so if you're looking for more intense energy, you can use more than one serving (we do not recommend exceeding 3 servings per day) or possibly a stronger preworkout like DyNO. To be sure, test your caffeine tolerance with one serving before adding more. Hope this helps. If there is anything else we can assist you with please do not hesitate to contact us. Thanks again, RSP Nutrition

User questions & answers

Question:	What are the mg's of the l-arginine and l-glutathione
Answer:	It’s 500 mg of nitrosigine, which is arginine and silica combined... better absorption than just arginine. 200 mg glutathione.
Question:	What is the difference between this product and L-argenine
Answer:	This product Has Inositol-Stabilized Arginine Silicate, which just boost your levels of arginine ( an essential amino acid ). So in that aspect, not much difference. However, like most Nitric Oxide boosters, this contains a good amount of L - Citrulline, another non-essential amino acid thats ends up just getting converted to L - arginine by your kidney. Long story short, this product is designed to significantly boost your nitric oxide levels and cause intense vasodialation. The product also contains some other stuff, but I hope this answers your question.
Question:	Is this all natural supplement
Answer:	Nitric oxide is naturally occurring in the body, as are the amino acids (protein building blocks) glutathione, arganine and citrulline; which can come from food like meat and eggs. Citrulline can also be converted to arganine in the body and, I believe, vice versa. As for the nitrosigine: I think that's just a trade name for a nitrate compound. That exact compound may not be strictly "natural", but nitrates certainly are. Nitrates get broken down into nitrites, which react with arganine to produce nitric oxide, a powerful antioxidant and vasodilator. It allows blood vessels to relax and widen, thereby increasing blood flow throughout the body. Exercise and food combinations like meat and eggs for arganine; and carrots, beets etc for nitrates, can also increase nitric oxide levels. I think this supplement is just a more condensed, focused approach to acheiving that goal. As with any supplement, they advise asking your doc before use.
Question:	is it kosher
Answer:	Veggie capsules typically are. Gelatin would make a tablet non kosher. But capsules don’t need binding agents like that bc it’s a powder mixture.
