The Prohormone Blueprint Part 3: 1-Andro (The Precision Striker)
If the 4-Andro base is your Franchise QB, 1-Andro (1-DHEA) is your elite WR1. It doesn’t manage the game; it scores the points. 1-Andro is engineered for one specific outcome: the surgical application of lean, dry muscle tissue without the "wet" side effects of traditional cycles.
The Surgical Logic of 1-Testosterone
1-Andro undergoes a two-step conversion into 1-Testosterone (Dihydroboldenone). This is a completely different animal than standard testosterone:
- The 2:1 Anabolic Ratio: 1-Testosterone is roughly twice as anabolic as standard testosterone. It’s designed for high-efficiency muscle protein synthesis.
- Zero Estrogen Conversion: Because 1-Andro cannot aromatize, you face zero risk of water retention or bloat. This is the "Hardener" that creates the recomposition effect, looking leaner and more vascular because you aren't holding subcutaneous fluid.
The Efficiency Math: Trial vs. Reality
The industry standard often cites a 330 mg daily dose based on famous clinical trials. But the Architect looks at the variables those trials ignored.
- The 3% "Bioavailability Tax": Most trials used raw 1-Andro powder or no ester tablets with poor delivery and zero fat pairing. At 330 mg with only 3% absorption, the body only utilized roughly 9.9 mg of active hormone.
- The Architect’s 15% Rule: By using Chosen 1 (Blackstone Labs), which utilizes a Liposomal delivery system, and pairing it with 25g of fats, we increase bioavailability to roughly 15%.
- The Result: Taking just two tablets of Chosen 1 (130 mg total) delivers approximately 15.5 mg of active hormone to your system per day.
The Ester-Weight Factor (The Hormone Yield)
When a hormone is "esterified," part of the weight of each milligram is the ester itself, not the hormone. To be surgical, we have to calculate the "Hormone Yield" for each of the three components in the Chosen 1 blend (assuming an equal distribution for the sake of logic).
- 1-Andro Base: 100% Hormone Yield.
- 1-Andro Caprylate (C8): This is a medium-long ester. Its molecular weight means it provides roughly a 70% Hormone Yield.
- 1-Andro Undecanoate (C11): This is a very long-chain ester. Its yield is lower at roughly 63% Hormone Yield.
Average Yield for 65 mg of Chosen 1:
If we average these out, each 65 mg tablet provides approximately 50.5 mg of pure 1-Andro base equivalent.

The Bioavailability War: Trial vs. The Architect
Now we apply the "15% Rule" (Advanced Delivery + 25g Fats) vs. the Trial’s likely "3% Reality" (Raw Powder).
- Clinical Trial (330 mg @ 3%): 330 mg x 0.03 = 9.9 mg per day reaching the system.
- Chosen 1 (1 Tablets @ 15%): 50.5 mg x 0.15 = 7.57 mg reaching the system.
- Chosen 1 (2 Tablets @ 15%): 101 mg x 0.15 = 15.15 mg reaching the system.
- The Result: (1 Tablets per day): = 52.99 mg reaching the system per week.
- The Result: (2 Tablets per day): = 106.05 mg reaching the system per week.
The Triple-Ester Blueprint: Chosen 1
I recommend Chosen 1 because it utilizes a three-ester matrix to ensure your "Striker" never leaves the field.
- 1-Androstene-3b-ol,17-one (Base): Immediate conversion for a quick spike.
- 1-Androstene-3b-ol,17-one Caprylate: The "Middle Distance" bridge for sustained levels.
- 1-Androstene-3b-ol,17-one Undecanoate: The "Marathon" ester with a 63% hormone yield, ensuring long-term systemic saturation.
Taking just two tablets of Chosen 1 with the 25g Fat Rule and the Liposomal delivery system actually puts 53% more active hormone into your system than the massive 330 mg dose used in the famous clinical trials.
This is why you don't need to be a "pill-popper." You need to be an Engineer.
- Base: Hits the system immediately (The Sprint).
- Caprylate: Bridges the gap (The Middle Distance).
- Undecanoate: Provides the long-term saturation (The Marathon).
By using three esters, Blackstone Labs is ensuring that your WR1 (1-Andro) is always on the field, 24/7, without the "crash" that comes from no ester tablets.
