Tried albuterol (similar effect to clen, less side effects). My reason for use was weight loss, as it raises BMR, but it also has an anabolic action. Commonly used by bodybuilders in the cutting phase of their training programme, in the immediate lead up to a competition. I didn’t see much effect, but think my dose was too low.
Also used Ipamorelin and GRF1-29, both of with increase the body’s release of endogenous growth hormone. Reason for use was healing from major spinal surgery, as GH increases rate of muscle and collagen synthesis. Major effect, even the surgeon was amazed at the amount of healing that had taken place in the short time frame between surgery and my 1st follow up.
All the above are banned substances on the WADA list. Albuterol is easy to test for, the other two are very difficult & expensive to test for, so not in your every day doping tests.
