Increases Size, Strength, Libido & More!


Prohormone cycles are great for a number of things -- increased size, strength, libido, and more. Essentially when on cycle, you feel like King Kong on crack. But, like all good things in life cycles must come to an end. When they do, that’s when you face a critical juncture in the road -- run a proper Post Cycle Therapy (PCT) or take a gamble with your vital organs and blow it off.

Hint hint, you’re supposed to choose option 1!

Choosing the right PCT product can be complicated (and expensive!) though, as you typically need multiple products to ensure full and complete protection and hormone restoration. Not anymore thanks to Primeval Labs!

Sanctuary is your one-bottle solution for the most complete and comprehensive PCT ever!

Here’s how it works:

Sanctuary Ingredients

Bulbine Natelensis (750mg)

A South African herb traditionally used as both a natural testosterone booster and aphrodisiac, Bulbine Natalensis helps increase testosterone levels and testicle size, Luteinizing Hormone (LH), and Follicle-Stimulating Hormone (FSH).

Even more vital to PCT, Bulbine suppresses estrogen production in the body, ensuring you don’t develop the dreaded gyno when coming off cycle!

Tribulus (750mg)

Commonly seen in natural testosterone boosters, Tribulus Terrestris is an Ayurvedic herb highly regarded for its ability to increase male virility and vitality. It’s rich in compounds known as saponins, which help to increases Testosterone and IGF-1.

Moreover, Tribulus also supports lean body mass and decreases body fat, this is especially important for you older men out there running prohormone cycles.

Atractylodes Macrocephala (500mg)

Here is one of the key ingredients why Sanctuary stands over the competition when it comes to comprehensive PCT -- Atractylodes Macrocephala.

This ancient Chinese herb has traditionally been used as a natural medicine for the treatment of a number of assorted digestive problems. Modern day scientists have uncovered that Atractylodes Macrocephala is unique in its ability to stimulate mitochondrial function and boost energy metabolism in skeletal muscle.

Atractylodes is also loaded with bioactive compounds known as atractylenolides which functions as exceptionally potent aromatase inhibitors, preserving your precious Testosterone levels.

Magnesium (450mg)

Magnesium is an essential mineral critical to a number of processes in the body including energy production, DNA construction, protein synthesis, and blood sugar regulation. It also happens to be one of the most prevalent minerals in the body, but unfortunately, most adults are deficient in it, especially high level athletes!

Primeval Labs includes 450mg 450mg of Magnesium Aspartate to restore optimal magnesium levels, which is a vital component to proper testosterone production.

Mucuna Pruriens (300mg)

Mucuna Pruriens is a plant rich in the dopamine precursor L-Dopa. This powerful compound possesses the exceptionally rare ability to cross the blood-brain barrier (BBB), where it can effectively exert its actions on hormones, specifically prolactin. 

L-Dopa significantly inhibits prolactin release, which is important, as high prolactin levels are associated with gyno or worse, liver and kidney disease! Additionally, L-Dopa also increases dopamine levels, which further suppresses prolactin as well as enhances overall mood!

As if you needed anymore reason to love L-Dopa, it’s also been shown to increase libido, testosterone, and Luteinizing Hormone (LH), all while reducing cortisol levels -- creating the ideal hormonal environment for muscle-building and your love life!

Maca Root (250mg)

Also known as Peruvian Ginseng, Maca is an adaptogen that’s traditionally been used to help cope with various stressors as well as enhance fertility and vitality. That’s not all though, as some other research indicates Maca improves endurance, learning and memory and decreases prostate size.

You can see why those Peruvian tribes were so keen on Maca!

DIM (200mg)

Diindolylmethane (DIM) is the primary bioactive constituent of indole-3-carbinol (I3C) -- an extremely powerful constituent of cruciferous vegetables such as broccoli or cauliflower. DIM is a miracle worker when it comes to suppressing “bad” estrogen production and inhibiting aromatase. Plus, supplementing with DIM even increases “good” estrogen -- yes, even the manliest of men need some estrogen from proper hormonal homeostasis.

N-Acetyl L-Cysteine (150mg)

N-Acetyl L-Cysteine (NAC) is renowned for its antioxidant and liver protecting qualities. As the primary substrate for glutathione (another potent antioxidant), NAC helps combat free radicals and oxidative stress. However, if you’re lacking in NAC, the body can’t produce enough glutathione to effective defend against these reactive oxygen species (ROS).

For this very reason, Sanctuary includes a full 150mg to provide all the essential building blocks to enhance antioxidant defense and provide additional liver protection.

5a-hydroxy-laxogenin (50mg)

Typically referred to as Laxogenin, 5a-hydroxy-laxogenin is a plant-based steroidal sapogenin derived from Smilax Sieboldii. These plant “steroids” help increase muscle protein synthesis and and decrease cortisol levels in the body, two vital factors when trying to continue building muscle when running PCT.

All in all, Laxogenin is great for improving performance, strength, and recovery, and that’s why it’s included in Sanctuary!

Zinc (30mg)

Zinc is another essential mineral required for a litany of biological and enzymatic processes in the body, none moreso important that testosterone production. High intensity training can deplete essential vitamin and mineral stores, which can adversely impact libido and testosterone production -- not good when coming off cycle.

Supplementing with Zinc counters that and not only ensures optimal testosterone production, but also increases IGF-1 release, a hormone essential for muscle recovery recovery and growth.

BioPerine (5mg)

There’s A LOT going on in Sanctuary and to ensure your body gets the most out of it, Primeval Labs includes 5mg BioPerine® for “absorption insurance.” Doing so enhances nutrient bioavailability and uptake so you get the most out of your daily PCT dose.

Vitamin D3 (1,000IU)

Commonly referred to as the “sunlight vitamin”, Vitamin D is an essential fat-soluble vitamin associated with optimal testosterone production. The problem is, most individuals are chronically deficient in it due to not spending enough time outdoors (too much TV and work).

Low Vitamin D levels not only lead to decreased free testosterone, but increased estrogen levels and body fat. On top of that, not having adequate Vitamin D has also been shown to be associated with lower fertility, increased depression, higher risk of cardiovascular disease and less lean mass. Now you understand why Vitamin D is so crucial to overall health!

To further drive the point home, Vitamin D also inhibits aromatase, which provides an indirect testosterone boost.

Sanctuary is Your PCT Solution!

Primeval Labs has included only the most effective, clinically-proven ingredients in Sanctuary, all at their full research-verified doses. This provides comprehensive support and protection for your most vital of organs as well as ensures optimal hormonal homeostasis when coming off cycle.

The search for proper PCT ends here, you’ve found your Sanctuary!
