Testosterone Booster to increase Lean Muscle Mass, Muscle Hardness, Strength, and Aggression
Hi-Tech Pharmaceuticals uses Cyclosome® Technology to formulate Sustanon 250®, a patented prohormone and testosterone booster designed to deliver anabolic compounds in a bioavailable form in one tablet. Sustanon 250® contains 150mg of four derivatives of the legal prohormone 4-androsten-3β-ol-17-one.
4-Andro is typically used as a bulking prohormone that supports muscle fullness, strength gains, and size gains. It is a precursor to 4-Androstenediol and 4-Androstenedione, which converts to testosterone through a two-step process. This prohormone is non-methylated and not toxic to the liver. It does slightly aromatize to estrogen, so an aromatase inhibitor is suggested after cycling.
Sustanon 250® also provides 100mg of 3β-hydroxy-5α-androstan-17-one, a prohormone produced in the body by the 5a-reductase enzyme. Taken orally, it converts slightly to dihydrotestosterone, which supports lean muscle mass, muscle hardness, strength, and aggression. Because this compound does not convert to estrogen, it was included to support strength and lean mass with less water retention.
Sustanon 250® is a Hi-Tech Muscle & Strength supplement with a high-dose, single-tablet prohormone profile. It contains a high dosage of 4-androsten-3β-ol-17-one to support muscle and strength, with 3β-hydroxy-5α-androstan-17-one added to cross the threshold for an anabolic response and reduce water retention.

THE SCIENCE
Cyclosome™ Delivery
Hi-Tech developed a proprietary process called Cyclosome™ Technology, which wraps hydrophobic prohormones and testosterone-boosting compounds in a water-soluble cyclodextrin complex inside liposomes. The idea works like a "Trojan Horse": the compounds pass through the liver intact instead of being broken down, reaching circulation through the intestinal lymphatic route rather than being lost to first-pass metabolism.
This matters because most oral testosterone-boosting tablets lose much of their active compound to that first-pass effect before it ever gets used.
Hi-Tech's double-loading technique increases how much prohormone each Cyclosome can carry and controls its release, which is what improves the bioavailability of compounds that otherwise absorb poorly.
What to Know About the Best Prohormones for Muscle Growth
- What a Prohormone Is: A prohormone is a compound the body converts into an active anabolic hormone. This is different from a dietary supplement like protein or creatine that supplies raw material or energy.
- Protein is Still the Base: No muscle protein synthesis happens without amino acids. Recommended daily protein intake is 1.4 to 2.0 grams per kilogram of body weight for building muscle mass and skeletal muscle from a source like whey protein.
- Where Prohormones Fit: Prohormone supplements are positioned for experienced lifters chasing specific fitness goals during a bulking cycle.Beginners, who get more from training, protein, and creatine first.
- Cycle Support Matters: Because prohormones affect hormone levels and testosterone levels, users often add liver and cycle support like Liver-Rx™.
- Know the Potential Risks: Prohormones affect hormone levels, so review the potential risks with a doctor first if you have a health condition, take medication, or are concerned about blood pressure. Also, remember that they can cause a false positive on athlete drug tests.
