There hasn’t been an adverse side effect reason to stop recommending these cycles. With correct combination of steroids, and anti-aromatase use when using larger amounts of aromatizable oral anabolic steroid, side effects at the 1000 mg/week level are usually not problematic for those who are careful with what they are doing.
As for trenbolone, a very small percentage do indeed find it unsuitable for them entirely, but the great majority can use at least 37.5 mg of Trenbolone Acetate Revalor per day, and a large majority have no real problem with 50 mg/day. The most common issue is night sweats, but that’s a harmless price to pay.
When people agree with trenbolone as a suitable choice for later cycles but not the first, this makes no sense as there’s no regard in which previous experience makes a difference. If trenbolone is suitable for an individual, it will be just as suitable in a first cycle as in a later one. Anabolic steroids are not like narcotics: it’s not the case that tolerance must be or is developed.
Why have such fast gains as these higher dose cycles promote, though? Is there really a need for the beginner to make really fast gains, as occurs with such cycles and proper training and nutrition?
Well, a beginner, as with anyone but even moreso, wants to gain some amount. If he can gain an amount he’s thrilled with in a short time, then he’ll be happy with a short cycle. If he gains little in a short period of time, then he won’t be happy with that, and will seek longer cycles.
I would far rather see the beginner use short cycles, no more than 8 weeks and in some instances as little as 2 weeks, and enjoy fast recoveries rather than see him remain on steroids for 12 or 14 weeks, or even longer, trying to eke out results from marginal dosing. There are many reasons for preferring shorter cycles, including better recovery. Short cycles do not work well with marginal dosing.
