Proper TestMix3 400 by Proper Labs is a high-potency testosterone blend containing 400mg/ml of three carefully selected testosterone esters, formulated for experienced bodybuilders and athletes demanding maximum muscle growth, strength, and performance enhancement.

This premium three-ester blend combines testosterone enanthate, testosterone cypionate, and testosterone decanoate to provide an optimal balance of rapid onset and sustained testosterone elevation. The high 400mg/ml concentration delivers powerful anabolic effects with reduced injection volume and frequency.

Proper TestMix3 400 represents an advanced testosterone formulation designed for those who have mastered basic testosterone cycles and are ready to take their physique to the next level. The synergistic ester combination ensures stable, elevated testosterone levels throughout the week with convenient dosing.

How Proper TestMix3 400 Works

The three-ester testosterone blend in Proper TestMix3 400 delivers:

• Dramatic increases in muscle mass and size

• Substantial strength and power gains

• Enhanced protein synthesis and nitrogen retention

• Quick onset of effects from medium-length esters

• Sustained elevated testosterone levels from long esters

• Dramatically improved recovery between training sessions

• Increased red blood cell production for superior endurance

• Elevated metabolic rate promoting fat loss

• Improved bone density and joint support

• Significantly enhanced libido and sexual function

• Increased training intensity, aggression, and motivation

• Better nutrient utilisation and muscle fullness

• Prevention of muscle catabolism during intense training

Dosage and Administration

Due to the high 400mg/ml concentration, Proper TestMix3 400 requires less frequent injections. Recommended administration:

• Intermediate users: 400mg per week (once weekly or split into two 200mg doses)
• Advanced users: 400-800mg per week
• Professional-level athletes: 800-1200mg per week (only for very experienced users)

This product is NOT suitable for beginners. Cycle length typically ranges from 10-16 weeks, with effects becoming noticeable within 1-2 weeks. Proper TestMix3 400 serves as an excellent foundation for advanced cycles and combines well with Deca-Durabolin, Trenbolone, Equipoise, Primobolan, or oral steroids such as Dianabol, Anadrol, Turinabol, or Anavar.

Potential Side Effects

Due to the high concentration and potency, side effects can be significant:

• Substantial water retention and bloating
• Elevated risk of gynecomastia (male breast tissue development)
• Increased blood pressure
• Severe acne and extremely oily skin
• Increased body and facial hair growth
• Accelerated hair loss in those genetically predisposed
• Complete suppression of natural testosterone production
• Possible mood changes, aggression, or emotional instability
• Potential injection site discomfort due to high concentration
• Increased strain on cardiovascular system and lipid profiles
• Potential liver enzyme elevation at very high doses

An aromatase inhibitor (AI) such as Arimidex or Aromasin is MANDATORY when using this product to manage oestrogen levels effectively. Regular blood work monitoring is strongly recommended to track health markers including lipids, liver enzymes, blood pressure, and haematocrit. Post-cycle therapy (PCT) should begin approximately 18-21 days after the final injection and should include Clomid, Nolvadex, and HCG for optimal recovery of natural testosterone production.

Who Should Use Proper TestMix3 400?

This product is exclusively for advanced and professional-level users with extensive experience using anabolic steroids. It should NEVER be used as a first testosterone cycle or by those unfamiliar with managing high-dose testosterone side effects.

Proper TestMix3 400 is ideal for serious competitive bodybuilders during mass-building phases, powerlifters seeking maximum strength development, or advanced athletes with specific performance goals. It requires thorough knowledge of cycle support, ancillary medications, and post-cycle recovery protocols. Those with pre-existing cardiovascular conditions, hypertension, prostate issues, liver problems, or kidney disease should not use this product.
