None of this is safe. Deca is the best secondary aas for mass
true dat, but some compounds are much safer than others
deca is supposed to be one of the mildest/safest with primo being the safest of all
most injectables are fairly "safe" but test is less "safe" than others, and tren is the most dangerous/toxic as far as injects are concerned (this is what i've gathered from all the shit i've read on this
)
of course it's all dose dependent but if all injects were say at 500 mg then it goes something like this (from safest to most toxic) 1. primo, 2. mast/deca, 3. eq, 4. test, 5. tren
but then you gotta figure out the effective dose for each compound so this makes it more tricky/complicated, for example effective dose for Ace is 150-300 mg per week and for deca it's 400-600 mg per week, and for primo it's like 600-800 mg per week
