Ready to crank up the intensity of you gains?!


Then behold, the most powerful, triple threat muscle builder stack on the market -- Primeval Labs Tri Andro!


Tri Andro has been specifically engineered to get you the most remarkable gains in muscle and strength in the shortest amount of time, bar none. It’s the most potent blend of muscle builders available created for the most intense weight lifters out there.


If you’ve tried solo Andro cycles before and really ready to ratchet up your results from a muscle builder cycle, Primeval Labs Tri Andro is your ticket to endless gains!


Why Choose Tri Andro?


Primeval Labs has formulated Tri Andro to contain three of the most powerful and effective legal muscle builders available today in 1-Andro, 4-Andro, and Epi Andro. The synergistic blend of these three Andro's aids muscle building, libido, and strength, allowing you to take charge in the gym or in the bedroom!

No lethargy, no fatigue, just pure aggression and lean mass gains!


Primeval Labs delivers superior quality muscle builders ensuring maximum absorption and nutrient uptake with the inclusion of the ground-breaking oral delivery method known as Liposomal Delivery Technology. This serves to maximize hormone levels in the body, while protecting your most vital organs from exposure to the harmful effects of other muscle builder supplements available on the market.


In other words, Tri Ando offers you all the benefits of a powerful muscle builder cycle, with none of the negative consequences!

Tri Andro Ingredients


Epiandrosterone (150mg)


Epiandrosterone (Epi Andro) is an incredibly powerful muscle-building andro that easily converts to Stanalone, a.k.a. Dihydrotestosterone (DHT). As a precursor to DHT, Epi Andro (3b-Hydroxyetioallocholan-17-one) effectively elevates DHT levels in the body, which serves to increase muscle hardness, libido, and strength.[2]

Furthermore, by increasing DHT in the body, Epi Andro helps suppress Sex Hormone-Binding Globulin (SHBG), a protein liver produces that binds to Testosterone, DHT, and estradiol. The results of this reaction resulting in less circulating estrogen and significantly more free testosterone.


Wait, isn’t DHT bad?!


In a word, no. DHT has been on the receiving end of a lot of bad press due to fear it makes your hair fall out and prostate swell, but that’s been blown out of proportion much to DHT’s detriment. In reality, DHT is critical in a number of functions in the body including erection quality, regulating estrogen / androgen balance, and heightening alertness. Some other research indicates that DHT might be even more beneficial at combatting catabolism (muscle-wasting) than even testosterone![1]

While some hair loss could be possible with Epi Andro, the more likely culprit for hair loss is estrogen.[2] One of the many benefits of Epi Andro, aside from building slabs of lean muscle, is that it combats estrogens in the diet, which explains why you don’t ever hear much in regards to hair loss from cycles of epiandrosterone.

Suffice it to say, the only thing you need to be worried about with Epi Andro is out of control muscle growth and gains!

1-Androsterone (75mg)


The most powerful single Andro you can legally get today is 1-Androstenolone, better known as 1-Andro. 1-Androsterone (3b-hydroxy-5a-androst-1-en-17-one) is an extremely powerful androgenic sex hormone, that does NOT convert to estrogen, meaning it’s 100% pure anabolic.

1-Andro undergoes a 2-phase conversion in the body that converts to the non-estrogenic 1-testosterone, a naturally occurring androgenic hormone that’s approximately 200% more anabolic than testosterone! Furthermore, 1-Andro has an anabolic-androgenic ratio of 1:2, which translates to significantly increased gains and aggression.

Additionally, since 1-Andro doesn’t convert to estrogen, it’s basically free of any nasty estrogen-related side effects and may even produce some much desired anti-estrogenic effects by manipulating the androgen : estrogen ratio. Taken all together, 1-Andro is the perfect Andro for building lean muscle, shedding fat, and increasing libido, strength and endurance!


Landmark Research!


The best part about 1-Andro is that its effects aren’t theoretical, they’re actually proven in scientific journals! The landmark 1-Andro study was performed in 2013 at Texas A&M University in College Station, TX.

Researchers enlisted 17 resistance-trained men and had them ingest 330mg 1-DHEA (1-Andro) spread across three doses each day for a period of 4 weeks. Test subjects increased their lean mass and strength in the bench, squat, and deadlift as well as lost fat mass.[4] At the conclusion of the trial, researchers declared that 1-Andro was comparable in lean mass gains and strength increases to a 300mg / week cycle of injectable testosterone enanthate![4]

Basically, this landmark study showed that 1-Andro is equally as effective as black market steroids!

Now you can begin to see why 1-Andro is included in Primeval Labs Tri Andro -- it flat out delivers results!


4-Androsterone (75mg)


The third component of Tri Andro’s muscle-building trifecta is one of the newer muscle builders on the scene, 4-Androstenolone, a.k.a. 4-Andro. 4-Androsterone is a naturally occurring DHEA metabolite whose chemical formula is 4-androstene-3b-ol,17-one. It resembles the molecular structure of DHEA but rather than having the double bond in the 5th position (as is the case with regular DHEA), 4-Andro has its double bond in the 4th position, hence the “4” in 4-Andro. This drastically alters 4-Andro’s effects in the body, which spells better results for your next cycle!

Following ingestion, 4-Andro experiences a 2-step conversion involving two enzymes, 3-hydroxysteroid dehydrogenase (3b-HSD) and 17-hydroxysteroid dehydrogenase (17b-HSD), which converts 4-Andro to Androstenedione and Androstenediol respectively, before finally converting to testosterone, the target hormone.

Since 4-Androsterone converts to 4-androstenediol, rather than 5-androstenediol (due to its different molecular structure), it possesses greater anabolic potential than normal DHEA. 4-Andro is also significantly less estrogenic than regular DHEA, which yields better results from your cycle and minimizes any risk of estrogen related side effects!


Liposomal Delivery Technology


What really separates Primeval Labs Andro's from the litany of other muscle building supplements on the market is the use of Liposomal Delivery Technology.


Like many orally ingested supplements, Andro's have poor bioavailability on their own due to degradation for all of the acids and enzymes they come across during digestion. Without the aid of delivery technology, you’d have to consume much greater amounts of Andro to get even minimal results from, which exposes your liver and other internal organs to significant stress, ultimately setting you up for trouble down the line.


However, Primeval Labs incorporates Liposomal Delivery Technology into every one of its Andro's (including Tri Andro) to improve bioavailability and absorption by as much as 1500%! That means, you can get maximum gains from the minimal effective dose, thereby ensuring that your vital organs are safe from any stress or harmful effects like other andro supplements on the market.




Consume 1 tablet 3 times daily, spaced evenly apart throughout the day.


Tri Andro is recommended in a 6-8 week cycle with at least 8 weeks off between cycles.


Your Ticket to Endless Gains!


Simply put, Tri Andro is the world’s strongest legal anabolic agent available. It’ll revolutionize your results in the gym and transform you into the ultimate Alpha male. Take charge of your gains and sex life like never before and witness the power of Tri Andro.


One you do, you’ll never be the same again!
