    Product Description

    Kynoselen has been discontinued by the manufacturer (Vetoquinol). We have found Troy Dynajec to be the exact same product as what Kynoselen used to be.


    Why buy Dynajec?

    • Bodybuilders typically use Dynajec as a PCT
    • Uses energy in your muscle tissue to promote growth
    • Contains potassium & magnesium, which synergize for strong muscle contractions
    • Allows the enhancement of strength, endurance, and lean muscle mass
    • Promotes quick and effective muscle recovery
    • Boosts protein synthesis as well as your metabolic rate for faster fat burning!

    What is Dynajec?

    Dynajec is used as an aid in the treatment and prevention of muscular disorders due to selenium deficiency. It is a non-steroidal supplement of several vitamins, minerals, heptaminol, and adenosine monophosphate. Considered to be an anabolic, but truth is that Dynajec is not a steroid. It can increase protein synthesis, leading to leaner muscle mass. Dynajec is very similar to Kynoselen in that it is a muscular stimulant, tonic, and restorative. It works by stimulating energy transformation, fat metabolism, and metabolic oxidative processes. It is a powerful fat burner, which combats fatigue, increases endurance during training, and facilitates recovery. We have had Kynoselen for sale on our website to customers around the world since 2003 and Dynajec is the new version of it. Buy Dynajec online in the United States and get it in your hands within 2 - 3 days. For international customers, you can still buy Dynajec here and we will get it shipped to you with no customs/border issues.

    Heptaminol and adenosine monophosphate are what makes Dynajec so desirable, which are the main active ingredients. It has been shown to improve overall strength of muscle tissue and minimize fatigue. Here is a list of all of the primary ingredients:

    • Heptaminol: It enlarges blood vessels and allows more oxygen to flow through your blood. Plain and simple...it gets good, oxygenated blood flowing throughout your entire body much more effectively.
    • AMP (adenosine monophosphate): A substance the body creates on the way to making adenosine triphosphate (ATP), a source of energy used throughout the body. ATP is everywhere in the body. It fuels muscles. Perhaps a reason why users of Dynajec report a boost in energy.
    • Magnesium aspartate: Promotes crazy muscle contraction, and is why it's in such demand with folks who want to get stronger. Magnesium also engages enzymes that are required for the break down of carbs and amino acids, which as you may or may not know...leads to protein synthesis.
    • Cyanocobalamin (vitamin b-12): It increases energy and appetite stimulation like no other. A lack of vitamin B12 results in weariness so it is just another reason to make sure you are taking it. Dynajec is a great way to ensure you are getting a very healthy dosage.
    • Selenium: An anti-oxidant...'nuff said.
    • Potassium aspartate: To prevent cramps and injuries, most coaches recommend you eat bananas before your workouts. It is the potassium in the bananas that keep your muscles from cramping. Potassium also synergizes extremely well with the magnesium to assist in stronger muscle contractions.

      I have competed and I now do a lot of pre-contest prep.. dieting is always the most important.. this is amazing at giving you energy, if you have a problem eating it does increase appetite.... everyone tells me how much it increases their sex drive. I love how it really does make you feel healthier .. other than the delivery system everyone I know loves this.

      Crazy impressed with dynajec! 

      Did an 8 week challenge contest to see who could come in most changed as if we're getting ready for a physique show. Diet was on point but being a natural body builder and not consuming many calories, (basically very high protein and greens) i did not expect to be able to salvage muscle during this cut or to get as lean in such a short period of time. Was able to burn through fat stores and get some of the biggest pumps I've ever had in the gym. Was expecting to see a dramatic decrease in strength as well. Ended up setting new prs on squats and deads. Pulled 505 followed by 405 for 8. Felt GREAT!! Energy, vascularity, strength, and shedding fat. Highly recommend this product! Thanks guys!

      Have used Kynoselen in the past and was bummed when they stopped production. Started Dynajec 4 wks ago and love it, i use 1.5 cc pre workout, gets the blood flowing, veins are nasty, and energy is high!! Did have to up my carbs a little as it seemed to accelerate my metabolism. So far its a 5 star winner

      I'm a regular customer and buy Kynoselen probably once every other month. Sucks that Kynoselen was discontinued, but the new Dynajec is pretty much the exact same thing. I've been using Kynoselen for 2 years now and after the first 5 dosages, it does exactly what Kynoselen did. Thanks for scrambling to find me a replacement!

      I think Crazy Muscle is the only place where you can buy Kynoselen online in the U.S I've looked at a lot of different places and they either have knock-offs or don't have anything. It's nice to place your order and have the product arrive in a couple of days.

      Just like the title, kynoselen is like eating a huge 100 lb banana because of the potassium. I normally get cramps easily because of my running, but taking Kynoselen...I haven't gotten any cramps since I started about 3 weeks ago.

      Reviewed by on 26th Aug 2013

      I have to admit that when I first found Kynoselen on this site, I was a little skeptical because of the low price. I spoke with somebody on staff and wanted to make sure it was a legitimate company and they were professional and quick to respond. Ended up buying a bottle of Kynoselen online and it was actually the exact same batch as the empty bottle I had at home, so I was relieved. The price for Kynoselen here is $25 cheaper than other places I've looked and I've been buying Kyno online forever.

      Got a happy customer here.

    31. Useful for PCT

      Reviewed by on 31st Jul 2013

      I use Kyno + Hemo15 for PCT after cycling. It does help with vascularity IF you are already low bodyfat (12% max).

      Above that, don't bother.

      I've never had problems with the AMP in it. Besides the normal product benefits, it helps me break-away from pinning (its a lot to roll to this after a proper cycle) . Even if you're a natural bodybuilder, I'd say give it a go and watch those veins pop!

    32. Increased Fat Burning and Vascularity

      Seems to help with shedding body fat. Most noticeable effect is an increase in vascularity. Don't notice too much in the way of an energy boost but get great pumps at the gym. Makes me sweat like crazy. Will definitely buy again.
