Test/Deca Mix 500

No. Neither ClinicalTrials.gov nor the studies we checked include this exact combination. Everything here comes from studies with testosterone enanthate, with nandrolone decanoate or with steroid users.

Yes. The ChEMBL database lists testosterone enanthate with first approval in 1953 and nandrolone decanoate with first approval in 1983, both with phase 4 as the highest phase. The finished blend is not a tested combination. Both are banned in sport. Everything here is the state of research, not a recommendation.

43 healthy men received testosterone enanthate or placebo weekly for 10 weeks, with or without strength training. The dose was 600 mg per week, the highest study dose here. Without training bench-press strength rose by 9 kg, with training by 22 kg plus 6.1 kg of fat-free mass. Mood and behaviour did not change.

In dialysis patients lean mass rose by 4.5 kg over 6 months (placebo 1.9 kg) and the walking and stair test got faster. HIV-positive women with weight loss gained 4.6 kg of weight and 3.5 kg of lean mass in 12 weeks. Both used low medical doses.

Strength athletes who took several steroids at once for 8 to 14 weeks had on average only 0.43 instead of 1.08 mmol/L HDL afterwards. Six weeks after stopping it had not yet recovered. Nandrolone decanoate alone did not change lipids in a blinded study over 8 weeks.

In a study of 140 experienced weightlifters men with at least 2 years of steroid use had an ejection fraction of 52 percent versus 63 percent in non-users. Heart relaxation was also weaker. There was more coronary plaque too. The higher the lifetime amount, the more plaque.

Testosterone from outside suppresses the hormone axis: LH and FSH fell quickly after the first injection. In the WHO study a cumulative 65 percent had no sperm after 6 months. After stopping it took a median of 3.7 months until at least 20 million per ml returned.
