deca and T3- why are they trashed so much?

[Gumaro]

a few years ago, these two drugs were among the best to use. now, most people talk against them. what changed?

ive heard t3 makes you weaker/feel weaker/whatever when youre doing lifting. im considering taking yohimburn and clen for when im off my cycle so i can shed some fat. its important to maintain strength, ya know?

Deca gives good gains but it can kill your libido and be hard to recovery from (HPTA). T3 is good for fat burning but it can wipe out your stamina and if you use too much or too long, you can damage your thyroid permanently.

I guess there are just safer alternatives to both these drugs.
