90 mgs of an oral? I can't recommend that.
And why do people still add clen to PCT? That's so early 90's. PCT is the worst time to add clen since clen is catabolic. (Yes, catabolic, not ANTI catabolic. Whoever started that misconception really had their head up their ass, yet, the
rumor remains).
Pharmacology 2002;65:38–48 Distribution and Muscle-Sparing Effects of Clenbuterol in Hindlimb-Suspended
Rats
"Based on their anabolic properties in skeletal muscles,
ß-adrenergic agonists are of interest as potential countermeasures to microgravity-induced skeletal muscle
atrophy. The levels of clenbuterol (Cb), a ß2-adrenergic
agonist, in both plasma and skeletal muscle were higher
in hindlimb-suspended rats than in their nonsuspended
Cb-treated controls. Cb treatment was shown to help
maintain the body weight in suspended rats, while reducing
the amount of mesenteric fat. However, hindlimb
suspension attenuated Cb’s lipolytic effects. In skeletal
muscle, the magnitude of response to unloading and Cb
treatment followed a general regional pattern and was
muscle and type specific. The highest magnitude of
response to unloading was in predominantly slow-twitch
muscles, and the least responsive were the predominately
fast-twitch muscles."

YEAR-LONG CLENBUTEROL TREATMENT OF MICE INCREASES
MASS, BUT NOT SPECIFIC FORCE OR NORMALIZED POWER,
OF SKELETAL MUSCLES
"1. Clenbuterol has been proposed for the treatment of muscle
wasting disorders, but its long-term effects on skeletal muscle
function have not been tested rigorously. We tested the hypothesis
that year-long treatment of young (6 months) mice with
clenbuterol would increase skeletal muscle mass and in vitro
measurements of specific force (Po) and power output.
2. Male mice (C57BL/10ScSn) were divided into treated
(n56) or untreated (n58) groups. Treated mice received
clenbuterol (1.5–2 mg/kg per day) in their drinking water for 52
weeks, following a staggered 3 day on/3 day off schedule to
attenuate the response to clenbuterol.
3. Clenbuterol treatment increased the absolute mass of each
muscle tested: the heart by 28%, extensor digitorum longus
(EDL) by 16%, soleus by 22% and tibialis anterior by 17%. For
treated compared with untreated mice, absolute Po (mN) was
greater in soleus muscles but not different in EDL muscles.
Absolute power output (mW) of the EDL and soleus muscles was
not different and no differences were observed for the specific
Po (kN/m2 ) or normalized power output (W/kg) of EDL muscles,
soleus muscles or diaphragm muscle strips.
4. We conclude that, following year-long treatment of mice
with clenbuterol, the mass of the heart and both fast and slow
skeletal muscles is increased, but the lack of any change in
normalized Po or power output indicates that clenbuterol has
little therapeutic effect on the functional properties of skeletal muscle."
