Peptides are defined as a compound of two or more amino acids in which a carboxyl group of one is united with an amino group of another. With the elimination of a water molecule, a peptide bond is formed. To put it more simply, peptides are just small proteins. When the number of amino acids are less than 50, these are peptides. When higher than 50, these are proteins. The peptides are therefore small chains of amino acid which are present in all cells of the body. There are several kinds of peptides: oligopeptides, polymers, proteins, neuropeptides and peptide hormones. These are synthesized naturally by the body. Peptides will therefore be used primarily to make a more abundant amount of hormones in the body. The latter will then produce new hormones such as Testosterone or corticosteroids. It is these two hormones that are considered anabolic or indirect anti-inflammatory.
Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
Another problem you may have happen will most commonly occur if you do not follow proper procedures laid out here or if you supplement with dirty or contaminated anabolic steroids; we're referring to an abscess. An abscess is an infection that will develop under the skin. Commonly the area will swell, turn red and be warm or even hot to the touch. If it is a full blown abscess, you will more than likely run a fever and the area will be unusually hot. If this occurs, you will need to go directly to the emergency room. If you do not start a fever, and it is not particularly hot, it is more than likely a sterile abscess, and you will simply need to wait out the dilemma. If it is unbearable you may still find a need to see a doctor, but a sterile abscess is not directly threatening to your safety.
